Now appearing on the market penetration is highest in the lithium-ion BN-V507 (Li-ion) As a result, this article will focus on lithium-ion battery. Know your notebook battery you need to clarify the following parameters: battery capacity, rated voltage, the normal temperature and so on.

From the size of the capacity of the main battery to determine mAh marked by its Chinese name is milliamperes. Milliamperes have a direct bearing on the size of notebook NP-F960 , NP-F970 by the use of the time, but it can not be generalized. Is not to say that the notebook battery supply capacity of the greater use of more durable in actual use in the process of life were closely related to the ability of notebook power consumption. We can imagine a notebook configuration, the higher the greater energy consumption, the greater the amount of running the operation of the passage of electricity will be the faster speed. Is the normal operating temperature of the BN-V514 can work in normal temperature range, in the use of non-normal temperatures likely to be dangerous (explosive), as well as unnecessary trouble (leakage, all of a sudden power). Date of production, which in some older models of notebook NP-FS21 , NP-QM71 will be in it directly in your piece of the NP-QM91D , Sony can use the length of time, this is a decision of the normal use of battery time for the important parameters. That is why we buy a notebook's battery when it is necessary to pay attention to the production date, even if the new batteries placed on the longer time of his life will be reduced accordingly. Expect to buy second-hand books for the users should pay attention to the aspects of the parameters. In this paper, the source notebook battery maintenance

How to tell what the parameters of this NP-FP50 , NP-FP70 , NP-FP90 ? From the picture we can see the type of battery used for Li-ion, lithium-ion battery that is. Rated output voltage 10.8V, for electricity 4800mAh. Of course, there are manufacturers, production, the normal operating temperature (0 degrees -60 degrees Celsius), and so on, the battery is currently used such a logo, you can enlarge the picture to the top of their notebook batteries some basic information.

The books of the external NP-QM71D , NP-QM91 structure, we can only look at some of the above parameters, the internal structure of many people believe that "dare" to understand. After all, the price of notebook batteries, or be called expensive. In fact, the essence of notebook BN-V607 , BN-V615 and rechargeable batteries common no-like, but the major vendors have models for their appearance for the battery case processing, so that if ripping out shell of the notebook battery, its internal structure and Ordinary batteries do not have the distinction of any kind, that is the major mutual constraint brand notebook batteries commonly used is the biggest obstacle to major notebook PC brand among independent design.

A closer look at the internal battery, which is a few cells of the group series and parallel circuits, in general, by a single battery capacity and voltage requirements of notebook batteries bound notebook batteries generally used after the first series of parallel approach to ensure its Voltage and battery capacity, an analogy, if a nominal 12.5V, 4000MAh notebook NP-F330 , NP-F550 , NP-F750, is generally composed of: 3 by the single voltage 4.2V, 2000MAh the BN-VF707 in series to achieve its The nominal voltage 12.5V, and then through a group of the same cell re-composition of the parallel circuit, the overall battery capacity to 4000MAh, this battery is generally said to 6CELL the battery pack. For notebook computer CGR-D28S , CGR-D320 , panasonic, as well as internal and external power supply are some of the principles of understanding, we will be able to work better in the day-to-day life batteries used in notebook. Then I talk about in their own laptop batteries for use in some of the experiences and suggestions.

First of all, get a piece of new batteries, a lot of users is in accordance with the practice of business tips in the lithium batteries used in the previous three charging even more than 12 hours. In this debate there are many on-line, but I found that in actual use, in fact, the majority of the notebook battery is not necessary. Why? Merchant said that in order to fully activate the cell's activity is entirely new wake-up battery. For this reason it sounds very full and credible, but we have not thought about this issue. If, notebook battery manufacturers have not yet been fully activated on the play, so the product can be said that only a semi-finished products. Can not require each user to master the skills to activate the battery, it is impossible in reality. As a result, the NP-FM50 , NP-FM70 factory has been a manufacturer of a fully activated. How are users to charge the BN-VF714 , BN-VF733 , JVC for 12 hours in favor of the use of it? Here the author gives a negative answer, the current notebook batteries have improved power management circuits and charging management system, when the battery reached saturation, the control circuit automatically switch to short-circuit, it is only after time in a waste of time Only. How can activate the battery of this activity? In fact, the manufacturer of the battery is activated in the absence of overload protection of the battery will discharge and recharge for a long time. Therefore, charging three times before the 12 hours is not necessary.

At times, a lot of users in the use of batteries in the very confused as to whether or not to wait until the battery run out completely before charging. In fact, this question should be answered like this, if you can do is certainly a good thing, but the premise is your problem too. Of course, I am talking about here is not referring to the excessive discharge, excessive discharge Practice has proved that the SB-L110 , SB-L160 is absolutely harmful, it will shorten the battery life. Therefore, when the notebook prompted a time of low power consumption will be able to charge the appropriate time. Some business has repeatedly stated that its lithium battery memory effect did not, this is very irresponsible. So when you have more CGR-D08S , CGR-D16S power when it is better not to charge for the good, because the memory effect is real.

Thirdly, the need for long-term battery should be how to do, into the proposed 40-50% of the electricity, placed in the shade of the low-temperature, the following parameters will be able to note the problem.

Storage temperature of 40% of the state-of-charge 100% state of charge
0 degrees 98% (after one year) 94% (after one year)
25 degrees 96% (after one year) 80% (after one year)
40 degrees 85% (after one year) 65% (after one year)
60 degrees 75% (after one year) 60% (3 months)

(Percentage of saturation at the time of the initial value of the relative percentage), of course, should be the best month to come up with a SB-L220, the battery can ensure a good state of preservation, and not let the loss of full electricity and cell damage.

Fourth, in notebook computers for use in "a month after the charge should be full-time release" if necessary. Notebook computer lithium-ion batteries used in general management with a chip and charge control chips. One-chip management in a series of registers, there is capacity, temperature, ID, state-of-charge, discharge, such as the number of values. These values are in use will gradually change. Personally, I think, in notebook computers for use in "a month after the full charge should take a" leading role of these amendments is to be improper, the value of the register, making the SB-L320 , SB-L480 , SB-LSM160 charge control and battery with a nominal capacity of the line The actual situation. This is why the work could not be omitted, after all, the high-priced notebook or effemination the aristocracy. Notebook battery maintenance

The use of the last turn on, how to make the book more batteries for a long time. Since you bought a laptop is to use it, the battery is one of consumables, as is bound to use the time to renew and scrapped. What books to allow a longer SB-LSM80 , Samsung life? Power-saving technology? Sleep? Hard to let hang? Reduce the brightness of the screen so? All these methods seem to be able to increase the so-called extension of the time. But you have never thought that such a meaningful extension of the time it? I do not run any open book process, do not open display CGA-DU07 , CGA-DU14 , CGA-DU21, not to hard, I can not reach a longer period of time. This would be absurd, is used to use the notebook, rather than high-sounding setting. I therefore propose that we make good use of the notebook, rather than about how to use the notebook. Perhaps, two years after the notebook market is another world, your books have reached the ranks of the retired. As long as we pay attention to day-to-day use of batteries used to, the normal cells can be used, there is no need to be timid.



Battery maintenance and the proper use of the techniques

05:01, 2008-Nov-28 .. 0 comments .. Link

Notebook battery can be said that the notebook is the most important source of power. No batteries to provide energy, will not be able to complete the special requirements of mobile office. Then our hands up to the notebook can only be a mobile PC only. The notebook's battery maintenance and use of the technique has become a headache for most consumers. Now in the notebook battery use and maintenance of this issue has always been different, I now combine their experience and advice of a Taiwan notebook brands Customer Service Center engineers after the BN-V416 to the use and maintenance of the situation to do a simple, And in-depth discussions will be friends in the notebook's Nikon in the day-to-day maintenance as well as the use of existing in a number of errors to do something to correct the hope that it can be helpful to our friends. However, the level of limited, if any omission article also hope our friends generosity of spirit!
A. purchased in the notebook batteries in a row after more than three consecutive 12-hour charge, to prevent "memory effect"

First ask a very dumb question: my friends have cell phones, right? In many of my friends use the phone very often, consciously or unconsciously in accordance with the business or remind others to do one thing, the phone is bought after the first three to the battery charge is 12 hours of electricity, and so on and then run out of power after the re - Charge. The reason is because my friends to worry about their cell phone BLM1 , Li-10B , Li-12B have "memory effect" memory effect refers to a specific cell for a long time subjected to the work of the cycle, automatically keep this particular trend. So every time someone said that if the battery is only 50 % Of the time started, then after the battery memory effect would be that the next time the charge can only charge 50% of the time, "do not get the necessary and sufficient." In fact, this "memory effect" is the nickel-cadmium and nickel metal hydride batteries for notebook computer lithium-ion BN-V408, memory effect is almost negligible.

With the gradual improvement of the manufacturing process, the current lithium-ion battery charging, and other characteristics of its deep-time charge at 4 hours, there is no need to charge the phone battery to get the law of notebook BN-V25U , BN-V306 , BN-V312 up, the laptop battery is dead on the charge , Put every two weeks or a month, will carry out a notebook Li-40B depth of discharge, the term sounds a bit scary, in fact, that is battery operated, and then not be used directly on the computer automatically shut down power on it. However, the number of times the depth of discharge should not be too frequent.

B, using the AC adapter when the battery should be discharged, the battery in order to avoid the "explosive charge"

Currently used in notebook on the market lithium-ion battery can be completed at 300-600 (some data may be more) of the charge-discharge process, we can calculate, now on the market to sell Centrino models of BN-V428 life in general Official data for more than 5-6 hours, the Pentium 4 models battery life of 3 hours, so as to lithium-ion battery can charge and discharge standards for the 600, its notebook batteries can calculate how long it will be able to come out. Some of my friends use the AC adapter when the battery down and take the worry is that if your battery is left inside more power, the results of the AC adapter plug on the results of the beginning of charge, resulting in their own waste batteries once the so-called " The number of charge. " In fact, this concern is uncalled for, because the notebook Li-42B ,Olympus power can not be 100 percent sure of the state, so using the AC adapter is certainly the time to complete the charge. However, many manufacturers of notebook computers are designed to have a battery protection measures, such as IBM's notebook power only less than 95% of the time will be charged, but not absolute, with no ability to design and fully rely on OEM notebook makers In this context, may have some weaknesses. If you really hurts your DB-L20 , NP-20 , NP-30, it may come off!

Battery explosion happened in a very small probability. But not absolute no, there are lithium-ion battery lithium batteries, among them a control circuit board and management to complete the charge and discharge, if the control circuit to lose some of the features of the original sensitivity of the direct or failure, can not be effective Current control, internal batteries temperature led to the explosion. The internal battery or batteries will short-circuit the explosion occurred. But the good thing is now available in the market of notebook products are based on the quality of foreign direct batteries or buy other people's NP-40 , Casio, relatively better quality. The domestic part of the lithium-ion battery manufacturers also import more from abroad and then proceed to manufacture batteries. So is an old phrase, in the selection of notebooks, as many as possible to prepare the budget to consider a number of major products of the right.

C, battery life did not meet official standards, sure the battery problems

All the friends to buy notebooks are concerned by this issue. Indeed, with the birth of the Centrino technology allows notebook battery standby time was longer possible. There are even notebook manufacturers is the mark of 10 hours, "a standard battery." In fact, this is only an ad to attract consumer attention only. At present, most of the laptop BN-V12U , BN-V22U can not reach the so-called "official standard", friends may recall the ASUS patented power-saving technology Power 4 Gear Technology (also upgraded version of the Power 4 Gear +), known as the M6 series of books using the NP-30 , NP-40 , NP-60 Time to 5.5 hours, but the ASUS sales of the book's author told the battery life time is about 3 hours. On the other hand, of course, the battery life of the manufacturing process there is not a problem we can solve the consumer. So battery life when there is no "official use of the standard battery," when my friends do not surprising, because not so long time is normal (if your notebook battery life to meet official standards do not Paizhuan, I am talking about most of the books).

If the friends of battery standby time not reached "the official use of the standard battery," then we can extend to a number of ways:

1,25 ℃ ~ 40 ℃ using standard external environment, the use of lithium-ion NP-80 , NP-120 , FUJIFILM can be best achieved if the temperature is too high, not only its own laptops or even slow down the speed of Death, and the battery in such an environment are also under Will affect the efficiency of its use. So as far as possible in the indoor environment using the notebook.

2, is not commonly used to disable the device. Peacetime use of battery-powered best time for the time being does not need to disable all out of the interface, such as wireless network card, printer port, infrared port, FireWire 1394 interface, and so on, will not waste a lot of battery power, specifically in the way " Control Panel "-" system "-" hardware "-" Device Manager "to find banned equipment, and then click on the" out "you can, BP-2L12 , BP-522 , BP-930when need be" opened ", is simple. After disabling the use of the results have been very clear, you can save a lot of power.

3, in-house equipment to reduce power consumption. Increasing the CPU frequency, high-speed hard disk will bring a lot of energy consumption and increased heat dissipation. Therefore, no special requirements, or the best use of the system or third-party software to control the speed of the hard disk, do not open too many windows and procedures of the CPU in order to avoid overload of work, it will not only reduce battery power consumption, and can also reduce powder Hot, "Qiu Laohu" there are still season, or do a little of the benefits.

D, start charging for notebook batteries are very harmful

Start charging in the end there is no harm? I once saw a buddy, my phone is charging-boot, and then from that sentence: wow! You dare to even start charging, the battery explosion you are not afraid! ? Although it is a joke, but they reflect a lot of friends in the use of misunderstanding. In the notebook, before some models if the design is the use of BP-945-powered, so even if the AC adapter plug, or the use of BN-V107 , BN-V114 -powered notebook, which is "not sufficient account of" the phenomenon of today's notebook computers are not so In the design of the danger, when the AC adapter plug, to immediately start to the external power supply and battery charging. So now there is no need to shut down the rechargeable.

E, long-term do not have to be placed on the side of the battery

The problem is often overlooked users. However, the problem may be small, and I talk to the engineers to tell my notebook, many notebook manufacturers on the proposed users will be in control of battery power more than 5%, such an approach is to remove the electrode passivation, as in the notebook battery factory The time has begun to slow self-discharge (activate the battery in the workshop on the matter has been completed, we do not need to worry about), a laptop is likely to be in the factory six months after the purchase of the consumer, and the battery discharge has also been half a year A. Here again my friends recommended that the long-term if the BP-911 , BP-406 do not have to use AC power adapter, the best notebook batteries to stay there for at least 40% - 50% more than the power to self-discharge, in the absence of electricity, then released from Let battery Can easily go wrong or even scrapped. You want to, ah, self-discharge must be put to, but not inside the power you put it, what ah, not strange if the question!

There is also a need to pay attention to the problem: If no long-term power supply and battery with the AC power adapter (such as students), put the battery in a cool dry place such as cabinets. This is to avoid humid environment, and if not whole, it is best to book and the battery separated, we do not believe cell phones to buy books and pay attention to when to see, business is not the battery and put the machine to separate?

F, but the death is no way to pull the BP-535 , BP-412 , BP-422

I met some friends some time ago that the machine does not shut down and even shut down illegal is not effective, to the great Guaijiu Guai "fainted dead" system it! The last big brother to direct one-to three-foot eyes closed, the second to pull the battery is only heard on the books Yishengcanjiao closed. In fact, this is very harmful, because in the standby mode, memory is the power of work and, if hastily taken directly from the Canon, data loss is inevitable, not to plug in the AC adapter when the battery check Such a practice is only do more harm than good.



Raiders wide notebook battery maintenance

Notebook from the birth of the day, the BP-511 on the controversy has never stopped, because the use of persistent notebook is a very important technical indicator, and battery capacity of the notebook's decision this important indicator. Because of technical reasons, the battery capacity will be affected by the use of the frequency-to-earth habits and the use of the storage environment and other factors to reduce or loss. In the end how can we maximize the use of the battery to play the effect of extending the battery life of it?

Many users of laptop batteries for use just to stay in the primary stage, how to protect theNB-1L , NB-1LH as well as the rational use of all batteries do not know. Whenever these big customers to complain about battery life is too short or long battery life is not at the same time is first of all carefully from the normal use of their own look for the reasons for this? Of course, these two problems caused by the battery does not rule out the reasons for their quality, but the vast majority of the current situation, improper use of man-made is a very common phenomenon.

Here are a few common errors in the future when the battery should pay attention to it! (Without all that for now the most commonly used lithium-ionEN-EL1 , EN-EL3)

For the first time the use ofEN-EL5 , EN-EL9, three times before the need to charge 12 hours?
This is totally unnecessary. Because the laptop has improved power management circuits and charging management system, when the battery reached saturation, the control circuit will automatically switch to the open state, so even if the charge is a long time to no avail.

In order to prevent the memory effect, should it run out of electric charge it?
Every time charge ofNB-2L , NB-2LH , NB-4Ldischarge before it is not necessary, but also harmful, as they had proved the depth of discharge the battery life will reduce unnecessary, when the proposal to use about 10% of the battery can be recharged when the. When the battery, of course, there are still more than 30% of electricity when it would be better not to charge, because the memory effect is real.

Insert AC, the battery should be to win in order to prevent repeated charge and discharge it?
I suggest that is: do not have to. You might get lithium-ion battery discharge natural to refute me, saying that if the natural discharge after the battery if there is access to power will be reduced by repeatedly charging and discharging of the battery life. I give you a "no" answer to the following reasons:
1. Notebooks now have the power control circuit design of the features: When theNB-3L , NB-5H is 90% (as most of the HP models) or 95% of the charge will be, and to achieve this through the natural discharge capacity of 2 hours a week , I would say when the batteries do not have to idle for about a month to complete in order to maintain the battery charge and discharge capacity at this time you should be concerned about the battery should be about training the body and not be left idle after the re-charge;
2. Even if the battery "unfortunate" was once again charge, the loss will not be brought about by the long period of time than theNB-5L ,Canon consumption caused by the large decline in the number.
3. Your data than you or your notebook batteries are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.

Long-term need to preserve battery power is full of it?
Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage)
Storage temperature of 40% of the state-of-charge 100% state of charge
0 degrees 98% (after one year) 94% (after one year)
25 degrees 96% (after one year) 80% (after one year)
40 degrees 85% (after one year) 65% (after one year)
60 degrees 75% (after one year) 60% (3 months)
It is clear that if the long-term preservation of theNP-FC10 , NP-FC11 , NP-FE1, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the ideal, of course, should be the best month to come up with a battery that can ensure a good save battery , Also would not let the loss of full electricity and cell damage.

As far as possible in how to use the notebook to extend the use of time?
1. To reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be used to extend the time;
2. PowerPlay and open SpeedStep power-saving features, and so on. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend theNP-FR1 , NP-FT1life;
3. The use of hard disk drive and the deceleration of the software. If NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the power consumption of notebook;
4. Make the best use of standby, sleep and other functions. When a longer period of time do not have a computer that allows notebook standby or hibernation, both to save power and extend the service life of the computer.
Notebook battery maintenance
1, the new battery would like to activate your notebook battery life, there must be a good start, which was purchased from the notebook when talking about. The new notebooks for the first time in the boot with a battery should be 3% of the electricity (which is generic manufacturers. If you are buying for the first time to open the notebook and found that the battery is full already, is sure to be used by others), this time, you Should not use an external power supply, the battery's power than is used up, until the shutdown, and then charge an external power supply. After returning home, but also to the NP-FS11 charge after the exhaustion of power, charging time must be more than 12 hours, repeated three times to do in order to activate the battery in order for future use to lay a good foundation.
2, to minimize the number of batteries used this method seems to give people the feeling that some small, but it is also the most effective. To know that the number of battery charging and discharging a direct bearing on the life of each of the first charge, battery on a step forward to retirement. We proposed to make full use of external power supply, the use of an external battery power will be removed. Some friends convenience, often several times a day in Plug Power, and notebook computers equipped with aEN-EL2 , EN-EL8, to do so, the greater the damage to the battery. Because each access to external power supply is equivalent to charging a battery,NP-FS21 , Sony??on the nature of the Zheshou.
3, after the exhaustion of power charge and avoid charging too much time regardless of your notebook to use nickel-metal hydride or lithium-electric power, it must be exhausted before sufficient power (electricity consumption of less than 1%), it is best to avoid the memory effect Methods. Lithium is no power on the memory effect, I have been in front of the business that is the error irresponsible guide. Li-electric memory will have the same effect, but its memory effect than Ni-MH small number of them. Cell phones with the same charge, when you charge the battery to the notebook, as far as possible to avoid too much time, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent the erosion of liquid chemicals, batteries to avoid contact with metal objects, such as access to note here is a little mention.

1. When no external power supply, if at the time the work situation for the time being less than the PCMCIA card slot, first proposed in order to remove the card to extend BATCL50L , TravelMate 290 life.

2. At room temperature (20-30 degrees) for the best of battery temperature, the temperature is too high or too low operating environment will reduce battery life.

3. Can provide a stable power supply in an environment where the use of laptop computers, will remove the battery can be extended by the battery life is simply not true. ASUS notebook computer on, when the full power rechargeable batteries, rechargeable batteries in the circuit will automatically shut down, so will not have been sufficient.

4. Proposed a three-month average of battery power correction action.

5. To minimize the use of the number of TravelMate 4000

The number of battery charging and discharging a direct bearing on the life of each charge a battery to retire a step forward. We proposed to make full use of external power supply,

6. The use of an external battery power will be removed.

Some users often several times a day in Plug Power, and notebook computers equipped with a battery, to do so, the greater the damage to the battery. Because each access to external power supply is equivalent to charging a battery, battery on the nature of the Zheshou.
7. Exhausted after the electricity charge and avoid charging time is too long

No matter your notebook to use nickel-metal hydride or lithium-electric power, it must be exhausted before sufficient power (electricity consumption of less than 1%), which is to avoid the best way to the memory effect. Li-electric memory will have the same effect, but its memory effect than Ni-MH small number of them.

8. Note the use of normal

Normally used to prevent exposure to prevent damp to prevent the erosion of liquid chemicals, TravelMate 2300 , Aspire 1680 Series , Aspire 1410 to avoid contact with metal objects, such as access to happen.

Laptop battery purchase Notes

The laptop battery life - as no more than 3-4 years, it may be in the process of users are most likely to be replaced. Two years later the use of laptop computers, battery consumption will find more and more rapidly. If possible, can replace the old batteries for new batteries to ensure the stability of the computer work.

When the need to replace notebook batteries, preferably with a selection of models to replace the battery. However, if the old computer is to use nickel-metal hydride batteries, in order for longer battery-powered, of course, can also be specified by the computer user's manual or manufacturer's recommended selection of models of lithium batteries. Although the nickel-metal hydride batteries because of cheap, but there is memory effect, but also in the same capacity next-to-weight ratio of lithium batteries, lithium batteries and have no memory effect, light and power for a long time, and other advantages, has become a laptop TravelMate 4500 standard . At this stage to use the notebook computer manufacturers of lithium BTP-ARJ1 ,A42-A3
due to the different power supply in time there are certain gaps and friends in the process of selection should be noted that different brands of batteries in the difference between the best of several brands compare.
In addition to the performance of the battery manufacturers supply a statement of the time, but also pay attention to the needs of its capacity. Battery capacity is usually AH (ampere-hour, ampere hour) calculation of the current notebook computer equipped with the most common is about 4000AH, and ordinary cell can be sustained for more than 2 hours. In addition to the battery power supply by the time the whole Computer power and heat dissipation, and other factors, the screen size (the bigger the more power), screen brightness, as well as the implementation of the work of all time will affect the power supply .

Now the prices of notebook batteries in 1000 up and down the ocean, accounting for about notebooks to 10% of the total price - about some of the ultra-thin models and even higher. The battery warranty, security of 3 months, half a year of security, but also the longest for 1 year; The reason why the battery warranty period is short because the notebook battery supplies belonging to the vulnerable, the frequency of recharging is a constant, A small one. Moreover, the notebook LCBTP03003 ,Aspire 1300 and other hardware, there is no room for repairs can only be replaced. For such a long period of warranty products (OZ), were invisible on the increased burden on manufacturers, so the purchase of laptop before the battery must ask the warranty period and conditions.

In addition, the purchase of second-hand laptop when not forget to try its built-in battery can be sustained for a long time and more work. Under normal circumstances, used in 2012 after sufficient power in notebook computers, Ni-MH battery can be some support for the work of the computer about 1 hour, lithium-ion battery can support nearly 3 hours, but relative to the terms of this new battery The request is already very low, less than the battery indicator shows a view from near the end of life.
Notebook Battery of the causes of damage
Laptop BTP-APJ1 , BTP-AQJ1 life is longer, often dissatisfied with the necessary and sufficient electricity, and even shows the battery has been damaged, the specific performance of the resistance is bigger in charge at both ends when the voltage rise faster. This charge was easy to control the line has been judged to be filled, the capacity of natural decline. As the larger battery internal resistance, discharge when the voltage drop, fast, so the system can easily mistaken for lack of voltage, less power consumption. Batteries found in the relatively short-time working hours, should take corresponding measures.



Notebook computer batteries on maintenance

Notebook computers are specifically designed for mobile computer, it goes without saying that the importance of the battery. The battery is a delicate consumables, as it has a memory effect, the effect of discharge, and only a limited number of rechargeable (Li-ion Acer laptop battery
for about 400 or so), plus the notebook dedicated high-capacity lithium batteries is very expensive, so Peacetime use, in particular, should pay attention to maintenance. Not pay attention to the maintenance of the barbaric use, make your laptop battery life of the rapid decline. I see a lot of second-hand laptop battery can only insist on less than 20 minutes is a long-term consequences of not pay attention to the proper use of the! The following on my own experience, we should talk about how to defend our beloved books ... ... the battery. First of all types of batteries, we should be aware that the laptop's battery at present there are mainly two: lithium batteries and nickel-metal hydride batteries. a, Ni-MH battery Ni-MH battery is a product of the relatively backward, are being eliminated, commonly found in second-hand laptop and a number of "million" China-made models. Ni-MH battery with the shortcomings of memory effect, battery capacity is relatively small, the time required to charge longer. The advantage of the number of rechargeable more generally up to 800 times more than some of the technology to improve the product can be as high as 1,200 times or so. What is memory effect? Regular use of rechargeable batteries you will be aware that Ni-MH battery should be completely exhausted after the electricity in charge, or because of the incomplete chemical reaction and reduce the chemical activity, that is, if your BTP-43D1 power not useful End, on the charge of battery to carry out, the battery's total capacity will reduce the rechargeable, battery life will be shortened. Memory effect to a certain extent, is reversible, in other words, we can be of some ways to eliminate the memory effect, bring it to reduce the power loss. However, these methods are very limited, in the event of a memory effect is not completely eliminated. Therefore, the use of nickel-metal hydride batteries friends must note that the battery used up as much as possible, conduct charge. b, lithium battery compared with the nickel-metal hydride batteries, lithium batteries to a number of advanced. Lithium batteries also have a memory effect (some magazines that lithium batteries do not have the memory effect, it is wrong), but the lithium battery memory effect much smaller than the nickel-metal hydride batteries, and to eliminate more than good. Lithium batteries are characterized by: do not have a clear memory effect, TravelMate 220 capacity is far greater than Ni-MH BTP-73E1, charging a relatively short time, but it was also shortcomings is clear that lithium batteries can only charge about 400 to 700. Most notebook computers used lithium batteries, lithium batteries and is keep the technical progress, and therefore I can buy laptops, as far as possible to consider lithium batteries. Note the clear cell type, let's take a look at how to use the Prevention of Cruelty to our battery: 1, the minimum use of battery. When you use the battery? Desk? Bedside? Car? The hotel? The author believes that unless it is a power not found, for example, in the car on the train, field and other places can not use the BTP-58A1 , BTP-60A1, but the use of AC power. Keep in mind that the battery is a consumable items, charge a small one, if you use the battery every day, then your batteries in about a year and you have to say goodbye (to count such ah, a day, 365 days once or twice a charge , Is almost 400 times a year or so, the lithium battery life will come to 400). You can look at your laptop warranty card: no matter what the brand is used, the battery warranty is up to a year (the cunning businessmen!), I recognize, of course, if you are in bed, with your ultra-thin notebook A novel look at the computer in a trailer behind the long line of AC power is a really nasty things, but taking into account the price of a new battery in 1000 to 3,000 yuan, I think I'll wait for the poor or you forget to put up with: ) 2, the use of AC power, battery to get down to avoid frequent battery charge and discharge. And you think different, even if you do not use the battery, which will own some of the electricity consumption, which is called discharge effect. General lithium batteries per day to release its own 0.2 percent of the electricity, and the Ni-MH battery will go from 2 to 4% of the electricity. Effects of discharge is every minute of every hour going. The laptop charging circuit, once detected the battery power has not filled, it will immediately charge, so you can imagine, the use of AC power, due to the effects brought about by the discharge process and the power consumption of notebook aspire 3000 battery , BTP-42C1 charging circuits The charging process has been carried out alternately, may be an hour battery charge and discharge scores, so that the battery on the considerable damage. Many famous international brands such as IBM, hp, Sony, Toshiba and so on in the design of computer time to consider this issue very well, such as IBM laptop battery will discharge monitoring until the discharge of more than 3% of the total electricity consumption when Will be a one-time charge. However, some domestic brands - I will not name here, and poor design make this issue a number of models on a very serious, which is why some friends bought a new machine, a few months down the TravelMate 240 Series has not been used on how Almost can not charge it! Therefore, if your laptop is not a very famous brand, in order to better security in the battery when not to take it down for good. 3, a new notebook computer for the first time start, the battery should be a 1% -2% of the electricity (which is the international practice, if you buy a notebook computer battery is already full of open, please note: it is absolutely Is not only the opening of the new machine! Sure it was used!), Then you should not external AC power, let the machine run out of battery power and shutdown. Then once the battery is full of electricity, and electricity and then shine again filled. This cell was active on the complete inspired. If you yield to the temptation of easy and skip this step, the battery will total electricity consumption to a certain extent. Although this will not affect the very serious, but I believe that at their own expense to buy the laptops for every fellow battery performance and on this point of time. 4, due to the long-term care not to use so that battery life substantially reduced, that is, with serious memory effect, we can take to the laptop battery discharge sufficient way to a certain extent this problem. The discharge method is as follows: remove the AC power, use battery-powered, and then open the computer, and many brands of notebook computers are low-voltage protection, that is, if the battery power is too low to force the closure of the computer. This feature is good, but we will not fully discharge the battery. Therefore, before entering the Bios (different brand of notebook computer into the Bios of different ways, be aware that when they look at the boot prompt), the closure of the power management, preservation from the post. Restart, restart Windows before the start screen that appears, press the pause button, making the computer to stay in the boot screen. Then do nothing until the computer's battery run out of electricity so far off. This process lasted about 1 to 3 hours, so that the battery power shine on the full. The BTP-550P is full again, take a look at the use of the time is not longer? (Note: This is a significant memory effect of the old BTP-52EW , BTP-63D1, if you are using a new laptop battery, it is no good!) 5, if carried out on the battery discharge, still to no avail , Or to the battery discharge method is too complicated, you do not, how do? Oh, I let you teach a trick to the ultimate nirvana - the battery discharge software! IBM's software, which discharge very easy to use, it can be said of it is something rotten into something wonderful. I have had a P166mmx notebook computers, cell only 15 minutes, after the IBM software discharge after discharge, it can even insist on watching a VCD! So that battery life has decreased substantially friends may wish to try the software may give you a big surprise Oh! The IBM software can be downloaded from the ftp site above. The address is ftp://ftp.pc.ibm.com/pub/pccbbs/mobiles/isbr01ww.exe. The download is an executable file isbr01ww.exe, it will automatically generate the implementation of a startup floppy disk. It starts with the system, we can achieve the automatic discharge. Concrete steps are as follows: (1) the implementation of this document isbr01ww.exe: Insert a floppy disk as required, according to the carriage return, followed by self-extracting process will generate a startup floppy disk and. (2) floppy disk with this guide to restart the computer, the screen appears Starting pc-dos ... ... (Note: The above operation by the AC power provided.) (3), and then unplug the AC power supply by tips, procedures for automatic discharge the BTP-44A3 until the machine Self-closing, said the discharge has been completed. (Note: When you see zero percent do not shut down the machine, it is necessary to wait for the closure of its own) (4) AC power plug, and then guide the computer floppy disk, the autoexec.bat automatically refresh operation procedures, ask you if you , Selected "yes", according to the carriage return, the process will soon return to the dos prompt A:>, that have been completed. (5) to turn off the computer, but it is not pulling AC power, to charge the battery until the green light so far. (6) more than repeat the process 3 times to get the best results. 6, if the above methods do not line ... ... 5 minutes of silence, please, your battery has not saved ... ... Wait! Do not rush to buy new batteries, many second-hand computer business to provide all notebook batteries for the "core" services. That is, through the shell to replace the battery inside the batteries, the batteries so that you rejuvenated. Usually for core prices, according to the battery, 200 to 700 yuan between this than to buy a new battery is much cheaper, and the result was not to buy a new battery and almost. But you have to be careful if you js-for-one old batteries, it would be a big loss. The notebook's greatest strength lies in its mobile performance. Have maintained a good, durable power of the laptop batteries, you can make anytime, anywhere, to work instantly and easily enjoy the high-brings you the convenience and freedom. I hope that the experience can bring you some real help and convenience.

Nickel-cadmium batteries
Traditional rechargeable battery is a nickel-cadmium batteries. They are relatively rough, easy to recharge (there are slow-fast). If the charging process is not handled properly, that is, memory effect, will cause the Apple laptop battery
to reduce the capacity of the original. The so-called memory effect in the battery is charging, the battery power has not been fully release, which will cause the loss of battery capacity. You can re-regulate the use of battery, which is fully discharged and then fully charged to improve the memory effect. It must be emphasized, "full" is. In addition, nickel-cadmium A1175 , A1185 also have an impact on the ecological environment. Because it is toxic cadmium. Even if the battery recycling has become very common, these batteries are also due to natural selection may have been thrown away.

Ni-MH battery
The laptop technology is a nickel-metal hydride batteries, its production has a number of years. Ni-MH battery is no longer the use of toxic cadmium and nickel-cadmium batteries than the storage capacity by 20%. In addition, the fact there is no memory effect. Attention to the frequent over-charge will reduce the A1078 life, so to very good control of the charging time. Ni-MH battery for about the price of nickel-cadmium M9324 twice.

Lithium batteries
The latest laptop batteries are used in lithium batteries, which can be used in notebook computers and mobile phones. And nickel-cadmium batteries, lithium batteries provide about twice the energy. There is a substantial improvement in performance, its price more than three times that of nickel-cadmium batteries.

Most of the laptop is fully charged takes eight hours, but generally speaking, in the first four hours, they will be able to charge a good 75% of the electricity, while the remaining 25% will take more time to go. The important point is that the M8403 must be recharged before the release of electricity End. The majority of users to use their laptop computers will use the power socket on the wall, they rarely use the battery-powered laptop. So that your laptop has been flying there is nothing wrong power supply in most new notebook ,M8244 , A1079, a sleep mode, which only consumes very little power. As long as you re-open the screen, will soon return to the last time you left the state. If you plug in an external power supply notebook computer, you should from time to time about the release of M6091 power. If you want to prepare for the use of laptop computers 23 hours, a good idea to unplug the plug, use battery power until the dry battery power, and then, and then planted it. On the other hand, if you do not use your laptop computer, they open it, the batteries run out and then re-plug in the power socket. This month, at least one or two

Notebook batteries by battery material nickel-cadmium, nickel hydrogen, lithium ion, and so on a few, lithium-ion M7318 charging and discharging of the need for precision circuit protection, industrial production and more complicated, so lithium-ion battery production costs higher.

Repair Methods:
First battery shell with a special tool called, and then investigate the reasons for failure after the election will be a good test batteries welded together, it is best to control the board of the relevant parameters, accurate debugging will be a good case letters , This battery can be used to normal.
In battery production, we U.S. imports of used PowerBook G3 , PowerBook G4 characteristics of the battery analyzer screen analysis. Asked the same group of cells tolerance of not more than 1% of the requirements of each battery charge and discharge characteristic curves exactly the same, the most important steps, if done well, give rise to a variety of issues, such as the standby time is short, do not charge full Can not charge the normal stand-by, life is very short, out of battery charge when the liquid corrosion notebook, or even cause an explosion or burning of the entire battery of computers and other accidents.

So when the A1148 core, dedicated to the use of welding equipment, generally in 0.02 seconds or less to connect with the film battery welding in prison. Do not use iron hand to carry out welding, or cause batteries attenuation performance or shorten the life span of the PowerBook G4 15inch can cause serious leakage or explosion.

It should be noted that different manufacturers can not be the same or different manufacturers batch of batteries with a battery in place, otherwise it will lead to a variety of possible failure.

Restored:
Aspects of the appearance of most of the models have almost no traces of a small number of models will be left open a slight traces. Internal consumption, for the past two years, the production model, after the restoration of the general performance will be worse than the battery when not better when used batteries are now out of the quality parameters, such as production in 1998 The lithium A1012 , M8511 power-saving single-core capacity for the general 1600mAH, and now the products of the same type of production capacity in 1800mAh, for the models in the near future, after the restoration of the original battery capacity of the basic, original battery life with the basic The same.



How notebook battery explosion-proof

05:16, 2008-Nov-26 .. 0 comments .. Link

Thin, large-capacity, long service life, these are the outstanding characteristics of lithium batteries. For this reason, lithium-ion FRU 92P1121
was quickly replaced by nickel-metal hydride and nickel cadmium 40Y6799 role as notebook computers, portable products, the preferred range of equipment. Near Period, discovered in a row of notebook battery explosion, the notebook battery time and again to the air waves, lingering fear that end users, lithium batteries in the end is the source of power or time bomb?

The study found the battery on fire mystery

In general, the current notebook lithium battery pack itself with better protection.

It not only by the series / parallel multiple batteries, also contains its own circuit substrates two modules: the protection of Circuit substrate (Protection PCB) module and the Smart Battery Gauge Board module, a set of FRU 92P1139 to protect its design, including the first-class Protection of the IC (to prevent the battery charge-off, let-off, short-circuit), the second-level protection IC (for the second time to prevent over-voltage), fuses, LED direction, temperature regulation, and other components.

In the multi-level protection, even in the power charger, notebook unusual, notebook battery can only be changed automatically to protect the state if the situation is not serious, often re-plug in after normal work can not Will be an explosion. Notebook battery exploded in the face of serious facts, ask the reporter of Xinhua professionals as well as a well-known manufacturers of design engineers.

According to the analysis of lithium 40Y6793 , FRU 92P1125 from Wu Waihu explosion or short circuit had caused sufficient, the biggest is the possibility of a lithium FRU 92P1141 at the time of manufacture, because the manufacturing process itself flawed, because the product can occur at any time there is a potential safety problems, such as should be The insulation between the metal poles of dust or copper foil and aluminum foil pierced the glitch is a lack of short circuits caused by micro. The former is the most serious, as a direct result of a large number of short-circuit and heat production, resulting in vaporization of some of the electrolyte, the battery case Stretch.

In addition, there is a rather exceptional power charger or laptop computers due to special reasons, lithium batteries to provide instant high-voltage / current strong lead over the serious charge, such as the charging voltage 12.6V by the sudden rise to 12.9V Or more, this time there will be a charge of high-flow generation, in-house circuit the battery charge current should be cut off action, but some of the lithium FRU 92P1137 over-voltage, over-current protection design is very weak, which may result in damage to the ThinkPad Z61t protection IC, So that the notebook battery to make the protection and the damage after a charge-off around the needle-chip lithium metal crystallization of the piercing point resulted in a number of micro-short-circuit, causing the battery temperature gradually increased until the final battery explosion, the fire occurred, This is a lot of notebook battery "hot" the main reason.

Add a layer of protective cover

At present, the mechanisms for the protection of the battery from the point of view, rechargeable 02K6651 pack in front of some of the traditional chip makers are mostly provided by the program play a precise control of charge voltage and charge current role in the over-voltage and over-current control does not provide corresponding Solutions. In this way, for the protection of the battery pack is entirely dependent on the battery itself, such as the charge-off protection, over-discharge protection, charge-off protection, have put current protection, over-temperature protection and so on.

Protection in place as a result of the need to prevent first-class IC protection MOSFET failure or short-circuit caused by over-voltage fault, so the second-level protection IC will generally be considered is the protection of the 02K6928 , 02K6620 , 02K7039 pack in the last line of defense. In this connection, e-convex (O2 Micro) Hong Shi Zhen product manager, said the different views, in his view, for the protection of the battery pack can be moved forward through additional controls on the charger to realize the detection and control of battery charging action, which will no doubt further enhance the level of protection, The use of lithium batteries on the protection of security.

To this end, O2 Micro in power management for portable devices developed by Cool Charge solutions, the integration of a project called Cool Battery Technology battery protection technology, which is the main feature of a traditional general Chargers do not have OVP (over Voltage Protection) and OCP (Over Current Protection) function to protect the two batteries, the technology has been Cool Charge IC chip embedded in them.

Cool Charge IC chip used, the power charger to a large extent, take on the responsibility to protect the battery. Cool Charge IC subject to the control of the charger in comparison with the traditional design (see Figure 1), needed to significantly reduce the external device And eliminate the need for Q3 and Q4 part of the design, reducing the failure rate. Preserved in the Q1 and Q2 (to improve the original design of components) between, Cool Charge IC set up a detection point, the factory settings, the Detection of point voltage and current settings are slightly smaller than the ThinkPad X60 , FRU 92P1167 manufacturers to set safety requirements. In this way, in charge voltage or current beyond the Cool Charge IC set up security after the voltage or current value, IC control Q2 off, the first battery Protective effect before the cut off charge; from the frequency of detection, protection, detection of ThinkPad Z60t time for the millisecond level, and through the chip to detect, you can easily achieve the level of seconds per million, can be very high The frequency of detection in a row, thus realizing the first step in the protection of the battery pack.



Notebook battery life skills

1. Activating a new ThinkPad R40

Generic manufacturers is a new notebook for the first time in the boot with a battery should be 3% of electricity consumption at this time, should not use an external power supply, but the battery's power than is used up, until the shutdown, and then add Power charge. And then also to the battery charge after the exhaustion of power, charging time must be more than 12 hours, repeated three times to do in order to activate the ThinkPad R32 , 02K6928.

2. As far as possible to reduce the use of the number of batteries

The number of battery charging and discharging a direct bearing on the life of each charge a battery to retire a step forward. We proposed to make full use of external power supply, the use of an external battery power will be removed. If you often several times a day in Plug Power, and notebook computers equipped with a battery, battery on the greater damage. Because each access to external power supply is equivalent to charging a 02K7054, battery on the nature of the Zheshou.

3. Exhausted after the electricity charge and avoid charging time is too long

Whether the use of notebook lithium or Ni-MH electric power, it must be exhausted before sufficient power (electricity consumption of less than 1%), which is to avoid the best way to the memory effect. Li-electric memory will have the same effect, but its memory effect than Ni-MH only a small number, only to the full power of the battery / use it only after the charge. Part of the charge, could lead to discharge the battery inside the batteries of different chemical properties, so the 40Y6797 performance will back down. Recommendations on the battery every few months to carry out a deep discharge the ThinkPad A20 , in order to optimize performance. This is accomplished through use of battery-powered, the battery capacity has been used to 0% (this time the system will automatically enter standby or hibernation state, according to the BIOS settings in different). And then connected to the AC charger has been full of up to 100%. After a long period of storage batteries, and battery discharge has a natural process, natural discharge has been finished, it does not affect the capacity of the battery.

The first charge, you should continuously charge the battery to 12 hours, and to completely Circulating charge, discharge three times (see the maintenance of a battery) in order to fully awaken to the new battery, this battery has not been stored for several months Use, it also recommended three complete charge and discharge. If a ThinkPad A20M in a row after 12 hours, after three or charge-discharge cycle still can not charge, this battery will not be able to use the need to be replaced.

At present, notebook computers are used in lithium-ion battery as its power source, for they were not equipped with a battery of the notebook, the notebook has been totally lost their sense of self, and a mobile PC-like no, so that the notebook computer The battery for notebook computers as a very important part.

In the high-temperature environment to avoid the use of lithium ThinkPad A21M , expert research, a state of high-temperature lithium batteries will accelerate the aging process, and not to the same extreme low-temperature environments. Low temperatures will reduce the activity of lithium batteries to reduce the notebook's battery life. Lithium batteries on a regular basis to activate processing, is fully charged and discharged, to allow the resumption of the largest-capacity lithium batteries. Practice is to close all the power management so that the notebook slowly discharge until they have no electricity, and then fully charged, can be repeated two or three times. The hot weather, as much as possible to maintain their own notebook batteries, notebook computers can better play its role. I hope your laptop battery will not be a worry for the maintenance of parts.

Because the lithium-ion batteries have a small size, high-energy density, no memory effect, high cycle life, high-voltage battery and low self-discharge rate, the vast majority of notebooks now use the batteries; are allocated to BenQ joybook5000 Battery as an example for everyone on the composition of the battery. We have seen JOYBOOK5000 battery package is actually a good group of batteries, a battery designed by the shell, ThinkPad R60 , ThinkPad T60 and protection circuit group consists of three parts. Niche here for details on batteries and circuits to protect an important part of the two, so that we can all work on the principle of the battery has a basic understanding in order to be able to use the correct maintenance of your notebook battery so that it Better for you.



Notebook Battery test the software and how to use Notes

05:14, 2008-Nov-26 .. 0 comments .. Link

In addition to the notebook processing power by the people's attention, there is an indicator of considerable concern to users, and that is battery life. In addition to Chinese consumers for carrying a notebook, more importantly, it does not need to be limited by the power, do not have to need a long "tail", in the absence of an external power supply can also be occasions to use as usual, so the battery for users It is a very sensitive thing, if put in a notebook around, but no battery power, and that scales with a weight belt is no different. Therefore, to understand their own laptop battery life is the time users on the occasion of the imminent and urgent need to avoid the use of the IBM laptop battery ThinkPad T40 , ThinkPad T41 when it "strikes". In this regard, what should we be more "authority" to detect the use of battery time? Nanbu Cheng us with a stopwatch to time? In fact, there is special software on the battery life for more objective assessment, for example, Battery Mark, Battery Eater, MobileMark2002 and so on. To introduce a more authoritative, but also the application of a relatively large number of software testing battery Battery Mark and the use of attention should be paid.

First of all, let us together find out the Battery Mark principle of it. In fact, Battery Mark use the built-in Graphics engine, Processor engine, Disk engine, Think engine, 4 engines to simulate the actual operation of the battery power consumption. 4 passage of the engine cycle between the non-stop operation of the simulation environment for users to a comprehensive ThinkPad T42 Series of tests to the specific situation. Every 2 to 3 minutes to test the software will automatically save the data to a specific directory below. When the battery will run out to complete, automatic shutdown before the last save as a result of the test will be the end result.

(Small knowledge: Graphics engine simulation multimedia notebook during the course of the operation. Processor engine is simulated in the notebook ThinkPad T43 in high-load environment. Disk engine simulation of actual use of them working hard. Think engine in practice simulation in a notebook idle state Environment.)

Usage

Some of the software to understand the basic situation, then let us take a look at how to operate the set.

Run the premise is that we have to charge the notebook's ThinkPad R50 to full power, then the system shut down a number of related management systems, which shut down the specific needs, see below.

First of all, should close the screen saver, if the screen open procedure, the test process, there may be a matter of time and activate the screen saver. Right-click on the desktop, choose "Properties" and "Screen Saver" page to screen selected as the program "(no)", then "application."

Click on the next page in the lower right corner of the "Power" button, be able to enter the power management, power scheme will be following all the items are changed to "never."

Switch to the "warning" page will be "less ThinkPad R51 Series alarm" and "a serious shortage of battery alarm" two Duigou are removed.

Switch to the "dormancy" of the page to see the "start dormant" in front of check whether there are (now the vast majority of notebooks will be able to activate dormant features of the system) and, if so, will remove the hook. Then click "OK", this has been shut down power management.

Battery Mark because of the Graphics engine needs to show some full-screen graphics, and some sub-standard screen resolution of 1024X768 resolution, the first adjustment will be mandatory for 1024X768, if more than 1024X768 resolution would not have had. Also due to FRU 08K8193 , 92P1060 Mark in full-screen display and in the middle between the switch and the task bar will have a negative impact, it is best to the task bar at the top of the total removal of the option.

All of the above are Windows power management bring their own set of procedures, some of the larger manufacturers will have its own dedicated power management procedures, the basic substance of the same, as long as the above, in accordance with the principles of setting it. (Of course, the above is set for the media for the evaluation, as individuals in the test of time, manufacturers can use its own allocation of special procedures, the test of time the 08K8214 , 08K8195 will be a little bit long)

After a series of settings above, basically there is no need to set up the other, then we can run the Battery Mark (the beginning of the procedure → → Ziff Davis Media BenchMarks → Ziff Davis Media Battery Mark 4.0.1), but we do not have to be anxious Disconnect the power supply, because there are behind the "long" things to look at it.

First of all we see is the screen License. At this point the page on the "Proceed" for the gray can not click, we simply rolled on the right side of the scroll bar at the bottom, "Proceed" button will automatically become available 08K8193.

Then the software will be prompted to fill in with the names of organizations, here we can not fill, do not care.

Following the confirmation page, click "OK" on it.

After "a lot of hard work", has finally seen the "truth." That just spent a long time ago and have only a little more than the beginning. Here are a few options:

1.Run (test)

2.Save results (save the test results)

3.Compare results (results of the comparison)

4.Help (help)

Click Run, software, hardware platform will be tested to see if it meets the requirements, if not you can not continue to run 08K8192 Mark. (Black mark in line with the machines that test the minimum requirements; yellow X machines, although that did not meet the minimum requirements, but also can finish the whole test; red X machines were unable to finish the whole test.)

According to the "next step" will show that the so-called Battery Mark minimum configuration requirements.

"The next step," there is a full page of English here, Battery Mark will once again stressed the resolution as well as the adjustment of the taskbar to hide the problem. At the bottom of the test is needed to install the font what the requirements are generally No missing fonts (not the lack of fonts).

You Dianfan feel, is an interface in the top of our concern is not specified. In order to avoid the testing process by the impact of other procedures, 92P1101 , 92P1089 Mark will automatically detect the program is running, side by side, if the yellow X, will not have an impact.

Then this page has suggested that if the software runs on Windows Me system, the first ME "system restore" feature off, or will affect the test.

Zhongyu Ao under this end, than the feeling of the Long March was also hard at this point "to complete" could be the beginning of the test (if it happened in front of a red X, will complete the button is gray.).

Fainted, was to deceive the feelings of the software. This is a test page92P1087 , 08K8194 Mark and machine power management procedures compatible Continue at the beginning of testing. (As the old models for the power management compatibility, Battery Mark for a dedicated power management compatibility less)

If the point of no big changes (only the bottom), 60 seconds after the emergence of Retry with the Cancel option at this time we should be bold by Cancel, will not fall into the cycle of death.

At this point a warning will pop up, suggesting Battery Mark will be no power management of the operation, according to the F3 to continue, according to exit Esc.

F3 test by entering the selection window, where we can choose Conditioning Run and Life Test of two test mode. Conditioning Run full load model, which is called 3 engine: Graphics engine, Processor engine, Disk engine, simulation notebook in a large workload of the state for a long time 08K8196 , 92P1102 . Conditioning Run compared with the model, Life Test model with a multi-engine Think engine, the main simulation in the practical application of these notebooks. Under normal circumstances, Life Test mode than Conditioning Run mode for a long time 30% -40%.

Choose to test the project, according to the F3, there will be a warning (Does not have the power management of the test). At this point the power adapter disconnected, and then press F3 to start.

If the wrong selection of test items, the need to withdraw from the case by F3, and then again by confirmation from the F3. Choosing the right to re-test to test (to remember the first first full power).

As for the test of time, depending on the specific model. As measured by the author before the Sony TX, C mode, running a total of more than 4 hours, while the L model run, a night to sleep, wake up the next morning, not run, a full 7 hours. However, under normal circumstances, even if another big-power (or small-capacity 92P1077 , 92P1073), have generally come to an hour, so we can go red cup of coffee, look at Bianhe Bian-series, read again, it is estimated that almost nine.

Notes:

1. Life Test in the test, the general is to adjust the screen brightness to 50 (some models in the use of batteries, will automatically reduce the brightness of the screen, this time to go without their adjustment), if the laptop's own Special software can be transferred to the best 08K8199 performance mode. And Conditioning Run mode, then the best would be transferred to a maximum brightness of the screen, the software settings for optimal performance mode.

1.Battery Mark memory of a certain request, if the memory of the relatively low death may occur, the proposed system, Win98, at least 64MB RAM or more, Win2k more than 128MB system, WinXP 256MB or more in order to avoid the crash occurred.

2. Attention to the settings should be revised, such as the power to use the program, warning, status bar, the screen saver, hibernation, we should double-check if there are any omissions, affect the accuracy of test results.

3. Battery Mark sometimes run the wrong time, the user need not worry as long as a good restart, but also in front and then continued to interrupt the test.

4. Lithium 08K8198 , 08K8197 , 92P1075 because of the limited number of charge and discharge, and occasionally you will not run on life have much effect, but if too frequent use of the Battery Mark test, will affect battery life.



On the notebook's battery-related knowledge

06:09, 2008-Nov-25 .. 0 comments .. Link

We buy a notebook, is the value of its mobility. Today's laptop computers, are all built of Health have a good, so we are all generally small size of the view that mobility is better. In fact, not necessarily to decide whether the notebook mobility of qualified, but also an important factor - PA3384U-1BRS. Why? We can imagine that if you buy a smaller size laptop, but battery life is not ideal, but not the kind of depressed mood to vent. Today, on Xiaobian to tell you is that, on the notebook's battery-related knowledge.

First of all, we have to find out the type of notebook batteries. At present, the use of the laptop batteries were divided into three types: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium batteries. They said that on the side: Ni-Cd NI-CD, Ni-MH NI-MH, Li-electric LI.

Nickel-cadmium (niege) Battery: It is the end of the 19th century by the Swedish inventor of such batteries have the so-called memory effect, what is the specific memory effect, we just give an example, you: When a battery is fully charged, It can be a continuous electrical discharge 60 minutes. Now we have to use this section of the batteries for electric discharge, discharge to 30 minutes to stop, and then this section for charging the PA3285U-1BRS , PA3191U-1BRS, good and sufficient power to continue to discharge after 30 minutes, each time for not fully discharged, after repeated operations N This section will have a battery memory effect, after the use of the process, when the battery discharge after 30 minutes, it is no longer the output current, that is to say, this section of the battery capacity has been cut in half. Ni-Cd memory effect is very serious.

Ni-MH battery: Ni-Cr early battery alternatives, greatly reduces the nickel-cadmium batteries in the existence of a "memory effect", which makes nickel-metal hydride Tecra 9100 , Satellite 1900 , Satellite A60-662 can be more convenient to use. Nickel-metal hydride batteries and nickel-cadmium PA3166U-1BRS , PA3331U-1BRS are basically the same as the cathode, are for the positive electrode nickel hydroxide. The main difference is the nickel-cadmium batteries used in the cathode active material is cadmium, nickel metal hydride batteries and high-energy based hydrogen storage alloy for the negative electrode, the nickel-metal hydride batteries have more energy.

Nickel-metal hydride batteries are the main characteristics of 5:00:

1, the energy density than nickel-cadmium PA3098U-1BRS twice as large.

2, round after round of 500 to complete the cycle of charge and discharge.

3, with the door side of the charger can be recharged in one hour fast charge.

4, self-discharge characteristics than the nickel-cadmium batteries, rechargeable can be retained for a longer time.

5, up to 3 times more efficient discharge in a row.

Lithium battery: lithium battery is from a class of lithium metal or lithium alloy anode materials for the use of non-aqueous electrolyte solution of the battery. 20 of these batteries is the actual success of the development of a new type of high-energy PA3084U-1BRS , PA3399U-1BRS , PA3395U-1BRS, has a high-energy, high-voltage battery, operating temperature range, long storage life, and other advantages.

Lithium batteries have a home page features 7:00:

1, high-energy high-density. Lithium-ion batteries are the same weight capacity of Ni-Cd or Ni-MH battery half of the volume is 40-50% of the nickel-cadmium, nickel hydrogen 20-30%.

2, high-voltage, a single lithium battery's voltage to the work of 3.7V (average), the equivalent of three series of nickel-cadmium or nickel-metal hydride Tecra 8000 , Tecra 8100 , Tecra 9000.

3, pollution-free, lithium-ion Satellite A65 Series , Satellite 2100 do not contain such as cadmium, lead, mercury and such harmful metals.

4, does not contain lithium and lithium-ion battery does not contain lithium, which is not on the Prohibition of the transport plane carrying aircraft in the lithium battery, and other provisions.

5, high cycle life, under normal conditions, lithium-ion PA3250U-1BRS charge and discharge cycles can be more than 500 times.

6, no memory effect, the memory effect is the nickel-cadmium batteries in the charge-discharge cycle, reducing the capacity of the battery. Lithium-ion batteries that effect does not exist.

7, the use of rated voltage of 4.2V voltage constant current charger can make lithium-ion battery in 1-2 hours to be in full charge.

Well, to find out about the battery type and characteristics, we come to find out the battery power of the issue.

There are a lot of people buy a laptop when the battery is about to start, and configure their business only on a single reading of the battery capacity of xxxxmAh not write battery voltage, in fact, the true reprint battery energy is not the size of the unit mAh but Wh. Battery power is based on a formula: battery power (Wh) = battery voltage (V) x battery capacity (Ah). Please note that here is the battery capacity Ah, not mAh, 1Ah = 1000mAh. For example, touch the PA3356U-1BRS ,PA3291U-1BRS block is the nominal 10.8V/2200mAh, it is the power of 10.8Vx2200mAh/1000 = 23.76Wh. The battery voltage and capacity in general will be marked on the battery, their calculations on the know. Some manufacturers will not be marked on the battery specifications, so we can only use the software to be tested.

Battery power in this respect we need to note that the replacement of the battery problems. And the battery charger is inseparable, that is, we are talking about normal power supply. If you want to replace the battery, you may choose the same model to use the same power, we can be assured that the replacement of business when you have to be clear. At the same time, the Chargers also need the attention. All notebook models of voltage and current, and even interfaces are different, common to a variety of models with "compatible charger", more expensive than the original. Even the interface is like, different voltage and current notebook is not working. If the voltage lower than the current standard of value, then the laptop at full speed in the work will lead to shortage of power supply, so that the battery is a lot of harm. If the voltage higher than the current standard of value, notebook and even the roots will not be able to boot or not to start charging, the board may eventually lead to burning. So choose a good charger, the notebook's PA3506U-1BRS , PA3591U-1BRS , Portege 4000 maintenance is very important.

There are many of my friends are concerned about this problem because there is no knowledge that it dares not reckless action. On the one hand, is a charger, if the batteries die, you can replace the batteries.

In fact, there is also a battery inside the batteries, long way from our usual battery used almost only to be larger. Many of the batteries are designed with a self-locking function, in other words, once the Satellite A10 Series , Satellite A100 out of control circuit, it will enter the self-locking state. Into the self-locking state battery, will not be able to work on the battery become obsolete, only certain way in order to unlock, which only professional engineers can. Therefore, we can only choose to replace the battery core. Battery replacement batteries can not be so arbitrary, and we hope to find more professional personnel to replace. If his replacement, an end-of-life battery is small, but that effort did not succeed in the fight against what is the most depressing.

Most people should be worried about is that the bombing of the notebook, in fact, we may very puzzled why the battery and then the explosion? The main reason is that manufacturers should be poor-quality work, resulting in the use of short-circuit in an explosion injuries. However, there are also a part of the reason is because the user caused by improper use. Many users may encounter such problems, only when the battery charge to 99% charge is less than 100%. In fact, this is only a problem if the charge to 99% can not continue to charge the battery, Satellite A70 , Satellite A75 that has been filled. If we or always sufficient, the last on the battery is likely to lead to an explosion.

On the notebook's battery maintenance, Xiao Bian here with you no more, I believe there are many on-line article on battery maintenance. With knowledge of the battery Xiaobian only know so much, we can provide help so much, and I hope you can help



Notebook battery maintenance of the five major errors

06:08, 2008-Nov-25 .. 0 comments .. Link

From the notebook of the birth of the day, the Fujitsu laptop battery on the controversy has never stopped, because of persistent use of laptops is a very important indicator of technology, and the capacity of the battery determines that laptop's important indicator. In the end how can we maximize the use of the battery to play the effect of extending the battery life of it? Now, we all set out for a few people often vulnerable to the misunderstanding: (without all that for now the most commonly used lithium-ion battery)
I, for the first time the use of batteries, three times before the need to charge 12 hours?
This is totally unnecessary. Because the laptop has improved power management circuits and charging management system, when the FPCBP80 reached saturation, the control circuit will automatically switch to the open state, so long as the line is full, does not mean that you will be able to charge more for a long time with longer The.
Second, in order to prevent the memory effect, should it run out of electric charge it?
Every time charge of battery discharge before it is not necessary, but also harmful. Practice has proved that as: the depth of the battery will discharge unnecessary to shorten battery life, when the proposal to use about 10% of the FPCBP77 can be recharged when the. When the battery, of course, there are still more than 30% of electricity when it would be better not to charge, because the memory effect is real.
Third, insert AC, the battery should be to win in order to prevent repeated charge and discharge it?
I suggest that is: do not have to! Of course, you can get lithium-ion FPCBP68 discharge natural to refute me, saying that in the natural discharge the battery, if there is access to power will be repeated charge-discharge, reduced battery life. I give you a "no" answer to the following reasons:
1. Notebooks now have the power control circuit design of the features: When the battery is 90% (as most of the HP models) or 95% of the charge will be, and to achieve this through the natural discharge capacity of 2 hours a week , When the batteries do not have to idle for about a month to complete in order to maintain the FPCBP63 charge and discharge capacity at this time you should be concerned about the battery should be about training the body and not be left idle after the re-charging.
2. Even if the battery "unfortunate" was once again charge, the loss will not be brought about by the long period of time than the battery consumption caused by the large decline in the number.
3. Your data than you or your notebook FPCBP95 are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.
Fourth, long-term need to preserve battery power is full of it?
Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage)
Storage temperature of 40% of the state-of-charge 100% state of charge
0 degrees 98% (after one year) 94% (after one year)
25 degrees 96% (after one year) 80% (after one year)
40 degrees 85% (after one year) 65 percent (a year later)
60 degrees 75% (after one year) 60% (3 months)
It is clear that if the long-term preservation of the battery, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the best. Of course, the best month we should come out with a battery, the PA2487U , PA3107U-1BRS can ensure a good state of preservation, and not let the loss of full electricity and cell damage.
Fifth, as far as possible in how to use the notebook to extend the use of time?
1. To reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be used to extend the time.
2. PowerPlay and open SpeedStep power-saving features, and so on. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend the PA3383U-1BRS life.
3. The use of hard disk drive and the deceleration of the software: NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the notebook.



Laptop battery maintenance and optimization

06:07, 2008-Nov-25 .. 0 comments .. Link

"Mobility" is different from the notebook computer desktop is an important characteristic. It is also because of the characteristics, so that the laptop battery inadvertently take on the responsibility of safeguarding the image. A lack of long Sony laptop battery
life of notebook capacity, it is impossible to take the needs of mobile office for a long time. And a lack of battery power to help the laptop, and its "Anytime, Anywhere" The advantage is that it is even more out of the question of.

At present, many users of laptop batteries for use just to stay in the primary stage, how to protect the battery as well as the rational use of all batteries do not know. Whenever these big customers to complain about battery life is too short or long battery life is not at the same time is first of all carefully from the normal use of their own look for the reasons for this? Of course, these two problems caused by the Sony PCGA-BP1N battery does not rule out the reasons for their quality, but the vast majority of the current situation, improper use of man-made is a very common phenomenon.

Many people think that the laptop's battery life is calculated in accordance with the use of life but actually it is not really play a decisive factor should be the number of full charge and discharge. This is not a special case of notebook computers, where all the rechargeable battery is so. Under normal circumstances, it is now generally used in notebook computer lithium-ion battery for the 400 or so take charge of life; Ni-MH battery life a lot longer to reach a thousand times take the necessary and sufficient, but has a strong Electrical memory effect, so although life expectancy than the previous lithium-ion batteries, but its day-to-day use of state, Ni-MH Sony PCGA-BP2NX battery performance is far behind lithium-ion battery.

We have the same human sickness and death, the battery is gradually after the aging and eventually death. As a result, proper use and maintenance of battery is particularly important.

General machinery of the new batteries will be in charge in advance to a certain degree of power for use in the test machine, so you will have to go home after the first machine to this part of the electricity charge for exhausted after work. And the future of every charge must ensure that the remaining Sony PCGA-BP2NY battery power consumption by as much as possible and then to carry out clean.

If the battery needs to be shelved for a long time to save, then left in the battery to ensure a certain degree of power, all manufacturers of whether the stay of the remaining number of different power, but I suggest all of us still full of power after a good save; other long-term non-use of the In the battery at least once a month depth charge and discharge must also work to be done, it is aimed at preventing the long-ion batteries have not been used in case of loss of electricity caused by the activity no longer be able to charge again.

In the computer environment, the use of power supply stability, we proposed to remove the battery, and using a separate power adapter power supply. The aim is simple to avoid frequent battery is not fully discharged in the case was charging. Our environment is absolutely impossible for insulation, so even if the battery is not used will be the same natural power, so that when connected to power again, will be carried out on the Sony PCGA-BP2R battery charge. This is a strong power of the memory effect of Ni-MH battery injury is a very large, although the lithium-ion batteries power the memory effect is almost negligible, but not a long period of charging and discharging will to a certain extent, reduce the Sony PCGA-BP2S battery Life. Of course, if you use the computer's power supply situation is very bad environment, do not do this, and the price of tens of thousands of laptop comparison, a cell is still relatively cheap, the baby lost his melon on a cost-effective .

Battery maintenance, no matter how, if the method shall not be treated in use, will never be able to give full play to its effectiveness. The same specifications as the battery, why in the day-to-day use and promotion by manufacturers of the difference in time, the use of so many subjects? This is a lot of customers after the purchase is a matter of doubt. Of course, this information does exist a number of misleading, as advocated by the number of manufacturers are in the extreme power of the test results, and our day-to-day use is not possible to reach such an environment. Even so, the difference would not have a lot of time, Sony PCGA-BP2T battery usually about 10-25 minutes (only writing word-processing, web browsing, and so simple to operate). In addition there may be a user of the power of some operations, such as watch video, play games and so on.

On the rational use of batteries and optimize methods, we have all the hardware from the laptop's own characteristics in terms of categories. Before talking about, let us come to the notebook computer in all hardware power of the smallest case for a simple sort, then followed by "LCD, optical drive, hard drive, memory and central processing unit, the other (interfaces, peripherals and so on ). "

1.LCD LCD

While the liquid crystal display LCD than CRT monitors have a lot of power, but in many laptop hardware, it is a big power. Among them, and the power consumption is directly related to the factors is the screen brightness and display refresh rate.

A. display brightness

LCD brightness of the full board from the rear of the screen placed in the back of the tube, it can be imagined, lamp brightness caused by the high and low power consumption is never the same. Therefore, if the use of Sony PCGA-BP2V battery -powered, visually to the extent permitted by as much as possible to reduce the display's brightness can save some electricity. In other words it had broken down in the middle of the user's screen will be on the all-black background can be adjusted to reduce the power consumption of this LCD is wrong. The use of all-black background as opposed to those who fancy background can indeed reduce the consumption of the system, which to some extent played the role of energy-saving, but to do so by saving energy is minimal, but LCD is not brought about by Because no matter what kind of background, on the LCD's brightness is no change.

Moreover, many users prefer to use the laptop screen saver, which may CRT display also has a protective effect, but the use of Sony PCGA-BP4V battery-powered laptop, it can be said is not useful . But now the screen saver can be said to be doing more and more fancy, running the screen saver when the system load it more, then naturally increased power consumption. It is therefore recommended that you leave the computer in time will have the option to close LCD, or the use of sleep function, or even shut down your computer. IBM users more fortunate, can be used directly FN + F3 to close the screen:).

B. display refresh rate

It is well known, LCD's refresh rate is a parameter in name only, because there is no LCD display is flashing, the general notebook refresh rate is fixed re-60Hz, reduce the increase is of no use. But when we refresh the screen a number of very fast operation, also will increase the power consumption. This explains why, as well as playing video games, Sony PCGA-BP71 battery consumption will be very soon, apart from the CPU, video card, and other hardware to increase the load, constantly repeated the action Shuabing is also a crucial factor in power consumption.

Unfortunately, however, the problem is basically not a good solution, we can only suggest that the use of battery-powered as much as possible when the video to see less and less to play the game ... ...: (

For IBM notebook computer, its unique power management software can be adjusted Battery MaxMiser laptop screen refresh rate, see figure, IBM's exclusive features:

2. CD-ROM

Many users believe that the drive was mainly due to the power of the laser head of the transmitting power. In fact, the first laser transmitter power consumption will necessarily despite electricity, but compared with the motor rotation, it is not a what.

In fact, the notebook has been in energy-saving drive up and down a lot of effort, we can feel the drive belt when the disk is idle, the motor will be in a very short period of time from the high-speed down to the last stop low-speed rotation. But read the CD-ROM, will be rotating motor, motor rotation must be consumed electricity. And the laptop Sony VGP-BPL2 battery has a CD-ROM problems, and that is when, or insert boot disk with CD-ROM will first turn on a few of the buzz, which is to consume electricity.

In fact, this problem can be solved. In addition to the use of batteries in less time as far as possible the use of CD-ROM, also known as the use of a Nero Driver Speed CD-ROM software to reduce the speed.

This is a very good green software, no need to be installed to run in the Nero Driver Speed Options can click on "Detect" button to detect the current drive supported by the speed of file, and can choose the language interface Sony VGP-BPS3 battery. Language from the menu, we can see that this software can show support for Simplified Chinese.

In the interface, the drive can read the speed and load to stop the rotation after the time for the definition and can run the software on the way to conduct a detailed definition.

In addition, if your CD-ROM support for the DMA transfer mode, then certainly keep in mind that in the Device Manager will open the function, and do not use PIO mode. This will effectively reduce the share of the CPU, so as to achieve energy efficiency.

3. Hard

With a similar drive, turning the motor power is also a factor in one of the other heads of the hard disk seek time will also have a corresponding movement of power.

A laptop computer hard drive energy-saving design is a certain period of time when the hard disk for users to put an end to read and write operations, will head to the auto, motor idling into the state, but the weakness lies in the design of hard disk heads will be ready to re - Since the hard disk seek testing the use of state. Each head of the mechanical movement will bring a certain degree of power consumption, the power management in the process of "free hard disk closing time" is Sony VGP-BPS5 battery set very necessary.

If your notebook computer using the IBM TravelStar hard drive, then you can use a software PowerBooster hard to achieve energy-saving operation, the software's interface is very simple, you just need to move on the "minimum energy consumption" and "the greatest performance" Between the blocks can be designated.

Another possible choice of models to update the hard drive because they can support a higher rate of transmission standards, but it also needs the support of the motherboard chipset. At present, the general might be able to see the hard disk are DMA/66 support and DMA/100 standard Sony VGP-BPS8 battery , although generally only for the speed to 4200 / notebook computer hard drive is concerned, DMA/100 in the transfer rate on the role of performance is not Out because of the internal hard disk transfer rate impossible to achieve the goal. But effectively reduce the share of the CPU, it does have a large role.

4. CPU and memory

Will be part of the reason why these two together is that they contain between the hardware is more obvious. When the computer's CPU speed is relatively high, compared with an hour of memory, the CPU is actually waiting for the memory; and when the CPU speed is relatively low, the memory is very large, there have been waiting for the CPU memory. In either case, the system will increase its operating capacity, at the same time is not conducive to energy conservation.

A. CPU

First of all, as far as possible choose to use mobile notebook computer CPU, as the mobile CPU for notebook computers has made energy-saving design. We were well-known features of the Intel SpeedStep is one of the great characteristics from the P3-600Mhz processor after, Intel mobile CPU in the official added this feature Sony VGP-BPS9 battery, which allows the CPU to use battery-powered clock automatically reduce the frequency of operation, In order to play the role of energy conservation. (Mobile Celeron processors do not have the features)

Intel SpeedStep:

If you are using Windows 98/Me/2000 operating system can go to the Intel Web site to download and install the program SpeedStep, in the process of the interface can be the CPU clock frequency definition, the user may need to use their own CPU running the designated frequency level. Such as IBM, SONY, and other brand of notebook computer power management program also offers a similar feature, although the same is also based on Intel SpeedStep, but much more detailed, provided a wealth of energy-saving models to suit the theme of the use of demand. Although Windows XP already embedded in the process Sony VGP-BPS10 battery, but regrets that it did not provide the definition of the procedures manual, the system will automatically install after the end of the default power management program will be adjusted to energy-saving notebook computer program, which is why a lot of Users feel that Windows XP installed on the computer system after a slow one of the reasons why.

If you choose this, your processor at full speed in any situation Pao Bule:

This can only choose:

OSHIBA laptop power management program

If the choice is another Pentium 3 processor notebook computer, as far as possible to opt for the Tualatin .13 micron core Pentium 3-M processor, as compared to the old .18 micron copper core of the Pentium 3, new Generation of processors in the power saving and performance have a lot of good.

B. Memory

Many people think that the DDR memory than ordinary power SDRAM memory, in fact, this is wrong because they overlook the

The use of DDR memory notebook computer with Pentium 4 is more and Nvida Geforce (ATI Radeon) graphics card such a big power, in power naturally is not possible to be small. But the memory on its own terms, DDR rather than power SDRAM, DDR memory because the voltage is 2.5v, and ordinary SDRAM memory for 3.3v.
Of course, it is not possible voltage changes, and we can change only the amount of memory. Under the system needs to choose the right size of the memory is Sony PCG-R505 batteryvery important, otherwise there will be because the memory is too small, causing the system to read a large number of hard disk space as virtual memory, it is natural to increase the power consumption.

The following is a different operating system memory proposals:

Windows 98> = 64M

Windows Me> = 128M

Windows 2K> = 192M

Windows XP> = 256M

5. Other (interfaces, peripherals, etc.)

We used USB, PCMCIA interface are charged, the power consumption is inevitable. Moreover, according to an external device used by different power consumption has also brought about by the will, for example, mobile hard drive power consumption than external mouse is great.

There is only one solution, which is in the process of using the Sony PCG-V505 battery as much as possible of those who spend less interface, unless forced to use. After the used equipment must remember to remove, because although the device to stop working, but the interface in order to maintain communications equipment and computers, must also consume electricity.

For some, we almost do not have to interface, you can consider it a temporary closure of the attention is not in the hardware manager of the property in equipment to disable the device, but the CMOS settings to Disable. For example, we are familiar with the infrared interface, it's time to time and then automatically open around the existence of infrared scanning equipment, this is the will power.

Finally, we made available to a proposal that is in the hardware configuration to allow as much as possible on the premise of the selection of the latest operating system, as in the energy-saving design, compared to their pre-generation operating system to improve many. In addition, a reasonable combination of Windows power management procedure or notebook computer manufacturers of specially designed power management procedures of the power savings are helpful.

Optimization of these operations can not play the role of the extended Sony PCG-Z505 battery life, but can really feasible as far as possible within the scope of the extension of battery life, so as to maximize battery performance. After more than one operation, battery life can be extended by about 10-15 minutes, the sounds seem to think that optimize the role of the less obvious, but it can not Xiao Qiao such a short span of ten minutes, it may be the most critical Computer has become an important moment in the life-saving information on the straw. Battery protection is not the same everywhere, or do not have to worry about batteries, a reasonable operating under the premise of rest assured that you use bold, it's better for our effectiveness is the key.



Notebook battery maintenance guide

Who does not want to be more laptop HP 338794-001 battery , HP PP2182L battery , HP 345027-001 battery for a long time, longer? Unfortunately, the Armada E500 is a consumable, has a limited life span. In the notebook of all the important parts, battery life almost as soon as possible accessories, but the right to use the appropriate charge and discharge, the correct storage, will be able to significantly extend the battery life of notebook computers.

A good habit to develop.
Want to live longer notebook EVO N410c, it has to be a good start, the new notebook for the first time in the boot when the battery in general with about 3% of the electricity, the first time do not use an external power supply, the battery's power than is used up, until the shutdown And then charge an external power supply. But also to the HP 342661-001 battery charge after the exhaustion of power, charge time to 14 hours, repeated three times to do in order to fully activate the battery in order for future use to lay a good foundation.

Second, the attention of a number of batteries used in point.

1. Have to use an external power supply when the HP Pavilion dv8000 battery , HP HSTNN-DB20 battery need to take it?

Notebook computer batteries will be placed in the long computer, customers need not worry that lead to shortened battery life. When the battery charge to 100% charge control chips (FET) will stop charging the battery. Subsequently, the battery power will be used to reduce the natural process. When the power down to 95% of the time, FET will be carried out to the drip-rechargeable batteries until the electricity back to 100%. This product is designed to extend battery life of the natural, so keep notebook HP 395789-001 battery placed in the computer will not affect the natural life of the battery.

Of course, if the use of an external power supply, you can check the battery down, will not be affected. However, if the shutdown in the following states, not connected to external power or batteries fitted, then the notebook computer's BIOS on the motherboard battery-powered electricity will not be added, which can lead to the maintenance of the system clock to run and maintain the BIOS information. Computer system itself should have an external power supply (including DC transformer or laptop Evo N600C , Evo N610C ), in order to continue to work; irrespective of whether the computer is open or closed, if the laptop HP 396008-001 battery is not installed, even if the computer is not being used, the computer should be With the external direct current transformer (external power supply) connected. In addition, your data than you or your notebook batteries are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.

2. Notebooks do not have long-term, how to save the battery?
We will face a period of time not to use the notebook, how to save the battery. Is full of power save, or save electricity put END? All along, there are diverse views.

Whether it is full or shine, in fact, are not true, let a long-term preservation of photoelectric batteries will lose their activity and even lead to the control Presario 900 , Presario 1700 circuit protection and self-locking no longer be able to use the full power will bring long-term preservation of the security problems, the most The ideal of preserve is about 40% of discharge to the preservation and then, afraid of lithium HP Pavilion dv9000 battery , HP EV087AA battery and high-temperature and humid, it should be placed in a cool dry place to preserve, but the temperature not too low, or capacity will be greatly reduced, about 20 degrees or so is ideal Preservation temperature.

Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage)
Storage temperature of 40% of the state-of-charge 100% state of charge
0 degrees 98% (after one year) 94% (after one year)

25 degrees 96% (after one year) 80% (after one year)

40 degrees 85% (after one year) 65% (after one year)

60 degrees 75% (after one year) 60% (3 months)

It is clear that if the long-term preservation of the battery, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the ideal, of course, should be the best month to come up with a HP EX942AA battery that can ensure a good save battery , Also would not let the loss of full electricity and cell damage.

3. As far as possible in how to use the notebook to extend the use of time?

(1) reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be effective to extend battery life; how to adjust the brightness of the notebook, please refer to the specific:
http://support1.ap.dell.com/cn/zh/forum/thread.asp?fid=25&tid=45151
(2) to open and SpeedStep power-saving features such as the PowerPlay. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend the Evo N620C ,Presario 1200 life;
(3) notebook hard disk, it is one of the components of the power consumption compared with that as long as power will be in a state of reading and writing, the process of the hard drive, the more the number of visits, the more power will be hard, so under normal circumstances do not In the large-scale software running on your hard disk, do not use the HP Pavilion ZT3000 battery in a separate case for Disk Defragmenter. The notebook is also a notebook drive in big power, full-speed work under the hard drive more than the cost of electricity, but also have a greater heat, so when we are in a long time ago not to use the CD-ROM will be the best time to CD-ROM From out in the drive. For frequent users of CD-ROM, the best way is to use virtual CD-ROM software to its virtual Presario 1800, this is the most power.
Can try to install through NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the power consumption of notebook;
(4) peripherals. As pcmcia card, as long as peripherals such as printers connected to the notebook HP 337607-001 battery , HP 337607-003 battery, even if it does not work in the notebook would consume power, so when we do not need to use these peripherals best when they get down from the notebook. If you do not often use the port facilities such as modem, com port, infrared, wireless LAN and so on, preferably in the BIOS to disable it.
(5) software. Suggested that the use of Armada M700 , EVO N400c , do not use some of the functions of the system, but demanding software. Regular customers have mentioned that the play of the game, or watch movies online, 6-cell battery can only be about 1 hour and many, in fact, this is a normal phenomenon, as well as the battery is too high expectations.
(6) heat. On the surface of the notebook and laptop cooling power of no contact, in fact, the relationship between the two are very close. As the notebooks are smaller and require its own cooling system to regulate the heat. When the temperature reaches a certain temperature when the program started fan, the notebooks will increase power consumption, so long as we can to help heat the notebook Presario 700, laptop temperature control, temperature control can reduce the time to start the fan, so it can be Extend notebook 398876-001 . PB992A life. On how to make a better notebook cooling, the specific reference to:
http://support1.ap.dell.com/cn/zh/forum/thread.asp?fid=5&tid=46556
(7) make the best use of standby, sleep and other functions. When a longer period of time do not have a computer that allows notebook standby or hibernation, both to save power and extend the service life of the computer. WINDOWS in the process of power management settings, we generally can be set to "Portable / laptop." At the same time, you can display the proposed properties screen saver is set to direct "black" and the wait time is set to 5 minutes PB994A , PB991A, so that when we do not operate for a period of time notebook, it will direct black, than this Other screen saver to run more power.
Battery on the controversy continues, if we have any objection to the Forum http://bbs.dell.com.cn question, let us discuss this topic in the debate.



Re-notebook lithium battery maintenance

06:24, 2008-Nov-24 .. 0 comments .. Link

For notebook computers, batteries can be said to be a more important component, and its performance is directly related to the lack of power in the notebook computer in an environment of the ability to work. The notebook computer HP PM579A battery , HP Pavilion DV4000 battery in many of the components is also an out-of consumables, it involves the laptop HP Pavilion ZD7000 battery maintenance and reasonable use of the forum is often discussed. On the notebook's battery kept on hold at the time exactly how much more than that to stay in power and whether or not the use of AC when the battery is removed, are not always what a unified answer. I watch a lot of foreign players in the experience, they will sum up the general point of view, for your reference. After reading this article, you will find many of their claims and generally we have received the recommendation of how many there are some differences.


Li-ion battery in a life cycle in general can be 300-500 times take the necessary and sufficient. Therefore, many people believe that as long as the use of batteries so that it can to a certain extent, played a role in extending the battery life. But they overlooked the battery is indeed the physical nature of the original, when the battery went down the end of the assembly line, its internal clock of life began to move about. Therefore, even if you do not have to set aside the HP Pavilion ZE2000 battery, lithium battery life of only two to three years will be able to come to an end of. Battery capacity caused by the reasons for the decline is due to oxidation caused by the increase in battery internal resistance. When the cell resistance reaches a certain point, this time even though the battery still be full of electricity, but the battery has been unable to release the stored electricity.

Caused by lithium HP PP2182D battery that the rate of aging by the temperature and time set aside to preserve the state of charge and the decision. I will give a table to illustrate two different factors on the battery capacity.

 

Forms can be seen by the high state of charge and high temperature accelerated the decline of the battery capacity. Therefore, if possible, try to charge the battery to 40% placed in a cool place to preserve. This will in the long term preservation so that the battery protection circuitry themselves in a state of the work. If the battery is fully charged will be placed under high temperature, so that the battery will cause great damage, the table has seen a 100% charge in 60 ° C to preserve the environment, 3 months after the battery capacity dropped by 40% . Thus, in addressing how to preserve the HP Presario M2000 battery , HP Presario V2000 battery
on this issue, at the same time we have been led to the focus of another controversy, and that is when we fixed the use of power, whether it is necessary to remove the battery? Until this question is answered in the Let's first look at the use of fixed-power battery when placed in the computer environment ... ... at this time due to the laptop charging circuit protection, so that the battery remained at 100% of full capacity, and this When the battery's temperature at least between 25-30 ° C, if the hot weather, the temperature will be higher, then from the table, you should be very natural to come to a conclusion that is so In fact would do damage to cells, which led to a decline in capacity.


However, despite the use of laptop computers, high temperatures will bring damage to the battery. However, the battery removed, only the use of fixed power, there will still be some danger that dust and moisture will cause some damage to the HP CGR-B1870AE battery, and laptop computers in order to avoid the use of the environment for all of a sudden power notebook computers may be caused by injury, so In general, manufacturers are warning users not to remove the battery. Of course, such a result can imagine the natural, often because of your HP Pavilion dv2000 battery in such a relatively poor business environment, it will not be long over, then you need to repair the new center to replace the battery, then the benefit The manufacturer is a natural.

Finally, an eye-catching is the focal point of lithium batteries how reasonable charge and discharge the problem. The lithium battery is carried out for the best part of the discharge, rather than fully discharged, and as much as possible to avoid the often complete discharge. Often the battery too low discharge of the HP HSTNN-LB31 battery so that the results can only be scrapped in advance, because if the battery on each unit below 2.5 volts, the battery's internal safety circuit will be switched on, this time of the battery would be some bad spent. Therefore, in order to avoid the occurrence of such cases, not to save battery power before it's too completely, but should be stored until a number of electric charge, and again before the first full use of electricity.

All in all, in order not to make your battery's too early to lose, so in normal use, you should try to abide by the following principles:

A. avoid full discharge, and often for lithium HP EV088AA battery , HP 417066-001 battery. The repeated and arbitrary charging of the lithium battery damage is very small, almost negligible.
B. will need to be set aside to preserve the lithium batteries under the shade, remember not to put the refrigerator. Avoid high temperature on the car, such as long preservation, the battery will charge to 40% after the placement.
C. If you do most of the time in the use of fixed power, remove the batteries placed in the shade.
D. no need to purchase spare lithium batteries for storage, so this is actually a waste of battery.

The HP F4486B battery is used to use, as long as attention to the reasonable use and custody of the way, there is no need for excessive care, it's as much as possible for it to contribute more masters of the performance is what matters.



Notebook battery maintenance of several errors

06:23, 2008-Nov-24 .. 0 comments .. Link

From the notebook of the birth of the day, the HP 346970-001 battery on the controversy has never stopped, because of persistent use of laptops is a very important indicator of technology, and the capacity of the battery determines that laptop's important indicator. In the end how can we maximize the use of the battery to play the effect of extending the battery life of it? Now, we all set out for a few people often vulnerable to the misunderstanding: (without all that for now the most commonly used lithium-ion battery)

I, for the first time the use of batteries, three times before the need to charge 12 hours?

This is totally unnecessary. Because the laptop has improved power management circuits and charging management system, when the HP HSTNN-DB02 battery , HP HSTNN-UB02 battery reached saturation, the control circuit will automatically switch to the open state, so long as the line is full, does not mean that you will be able to charge more for a long time with longer The.

Second, in order to prevent the memory effect, should it run out of electric charge it?

Every time charge of battery discharge before it is not necessary, but also harmful. Practice has proved that as: the depth of the battery will discharge unnecessary to shorten battery life, when the proposal to use about 10% of the HP DP390A battery can be recharged when the. When the battery, of course, there are still more than 30% of electricity when it would be better not to charge, because the memory effect is real.

Third, insert AC, the battery should be to win in order to prevent repeated charge and discharge it?

I suggest that is: do not have to! Of course, you can get lithium-ion HP PP2100 battery discharge natural to refute me, saying that in the natural discharge the battery, if there is access to power will be repeated charge-discharge, reduced battery life. I give you a "no" answer to the following reasons:

1. Notebooks now have the power control circuit design of the features: When the battery is 90% (as most of the HP models) or 95% of the charge will be, and to achieve this through the natural discharge capacity of 2 hours a week , When the Compaq Presario R3000 battery , Compaq Presario X6000 battery do not have to idle for about a month to complete in order to maintain the battery charge and discharge capacity at this time you should be concerned about the battery should be about training the body and not be left idle after the re-charging.

2. Even if the battery "unfortunate" was once again charge, the loss will not be brought about by the long period of time than the battery consumption caused by the large decline in the number.

3. Your data than you or your notebook batteries are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.
Fourth, long-term need to preserve battery power is full of it?

Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage)

Storage temperature of 40% of the state-of-charge 100% state of charge

0 degrees 98% (after one year) 94% (after one year)
25 degrees 96% (after one year) 80% (after one year)
40 degrees 85% (after one year) 65% (after one year)
60 degrees 75% (after one year) 60% (3 months)

It is clear that if the long-term preservation of the HP Pavilion ZV5000 battery, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the best. Of course, the best month we should come out with a battery, the battery can ensure a good state of preservation, and not let the loss of full electricity and cell damage.

Fifth, as far as possible in how to use the notebook to extend the use of time?

1. To reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be used to extend the time.

2. PowerPlay and open SpeedStep power-saving features, and so on. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend the HP Pavilion ZV6000 battery life.

3. The use of hard disk drive and the deceleration of the software: NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the power consumption of the notebook.

4. Make the best use of standby, sleep and other functions. When a longer period of time do not have a computer that allows notebook standby or hibernation, both to save power and extend the service life of the computer.

Sixth, final:

Of course, talking about more than just five regular user experience, as well as the general situation compared to confuse users. For the maintenance of notebook HP Pavilion DV1000 battery , HP PF723A battery , HP 367759-001 battery subject, I believe that as you use the more you will find, however, the same as the continuous development of the notebook computer, you may find problems in the future notebook computers may no longer Become a problem



Should Batteries Be Tossed or Recycled?

07:09, 2008-Nov-23 .. 0 comments .. Link

Today’s common household batteries—those ubiquitous AAs, AAAs, Cs, Ds and 9-volts from Duracell, Energizer and others—are not thought to pose as great a threat to properly equipped modern landfills as they used to because they contain much less mercury than their predecessors. As a result, most municipalities now recommend simply throwing such HP F2019A battery , HP F2019B battery away with your trash.

Battery Disposal or Recycling?
Nevertheless, environmentally concerned consumers might feel better recycling such batteries anyway, as they still do contain trace amounts of mercury and other potentially toxic stuff. Some municipalities will accept these HP OmniBook 6000 battery (as well as older, more toxic ones) at household hazardous waste facilities, from which they will most likely be sent elsewhere to be processed and recycled as components in new batteries.

How to Recycle Batteries
Other options abound, such as the mail-order service, Battery Solutions, which will recycle your spent batteries at a cost of 85 cents per pound. To find a company near you where you can drop off your old batteries for recycling, check out the comprehensive national database at the Earth911.org website. Meanwhile, the national chain, HP F1739A battery Plus, is happy to take back disposable batteries for recycling at any of its 255 retail stores coast-to-coast.

Older Batteries Should Always Be Recycled
Consumers should note that any old HP Omnibook XE battery they may find buried in their closets that were made before 1997—when Congress mandated a widespread mercury phase-out in batteries of all types—should most surely be recycled and not discarded with the trash, as they may contain as much as 10 times the mercury of newer versions.

The Problem of Rechargeable Batteries
Perhaps of greater concern nowadays is what’s happening to spent rechargeable batteries from cell phones, MP3 players and laptops. Such items contain potentially toxic heavy metals sealed up inside, and if thrown out with the regular garbage can jeopardize the environmental integrity of both landfills and incinerator emissions. Luckily, the HP F2024B battery industry sponsors the operations of the Rechargeable Battery Recycling Corporation (RBRC), which facilitates the collection of used rechargeable batteries collected in an industry-wide “take back” program for recycling.

Additional Battery Recycling Options
Consumers can help by limiting their electronics purchases to items that carry the RBRC logo on their packaging. Furthermore, they can find out where to drop off old rechargeable batteries (and even old cell phones) by calling RBRC’s hotline at 1-800-8BATTERY or by visiting the online drop location finder at RBRC.org. Also, most Radio Shack stores will take back rechargeable HP F2024A battery , HP Omnibook XE3 battery and deliver them to RBRC free-of-charge. RBRC then processes the batteries via a thermal recovery technology that reclaims metals such as nickel, iron, cadmium, lead and cobalt, repurposing them for use in new batteries.

 



Battery History

07:08, 2008-Nov-23 .. 0 comments .. Link

A battery, which is actually an electric cell, is a device that produces electricity from a chemical reaction. Strictly speaking, a HP F3172A battery consists of two or more cells connected in series or parallel, but the term is generally used for a single cell. A cell consists of a negative electrode; an electrolyte, which conducts ions; a separator, also an ion conductor; and a positive electrode. Continue with How Batteries Work/Battery Types
Timeline of Battery History

1748 - Benjamin Franklin first coined the term "battery" to describe an array of charged glass plates.
1780 to 1786 - Luigi Galvani demonstrated what we now understand to be the electrical basis of nerve impulses and provided the cornerstone of research for later inventors like Volta.
1800 - Alessandro Volta invented the voltaic pile and discovered the first practical method of generating electricity. Constructed of alternating discs of zinc and copper with pieces of cardboard soaked in brine between the metals, the voltic pile produced electrical current. The metallic conducting arc was used to carry the electricity over a greater distance. Alessandro Volta's voltaic pile was the first "wet cell HP Pavilion ZT1000 battery , HP Pavilion XZ200 battery" that produced a reliable, steady current of electricity.
1836 - Englishman, John F. Daniel invented the Daniel Cell that used two electrolytes: copper sulfate and zinc sulfate. The Daniel Cell was somewhat safer and less corrosive then the Volta cell.
1839 - William Robert Grove developed the first fuel cell, which produced electrical by combining hydrogen and oxygen.
1839 to 1842 - Inventors created improvements to batteries that used liquid electrodes to produce electricity. Bunsen (1842) and Grove (1839) invented the most successful.
1859 - French inventor, Gaston Plante developed the first practical storage lead-acid battery that could be recharged (secondary battery). This type of HP Omnibook XT1500 battery is primarily used in cars today.
1866 - French engineer, Georges Leclanche patented the carbon-zinc wet cell battery called the Leclanche cell. According to The History of Batteries: "George Leclanche's original cell was assembled in a porous pot. The positive electrode consisted of crushed manganese dioxide with a little carbon mixed in. The negative pole was a zinc rod. The cathode was packed into the pot, and a carbon rod was inserted to act as a currency collector. The anode or zinc rod and the pot were then immersed in an ammonium chloride solution. The liquid acted as the electrolyte, readily seeping through the porous cup and making contact with the cathode material. The liquid acted as the electrolyte, readily seeping through the porous cup and making contact with the cathode material."
1868 - Twenty thousand of Georges Leclanche's cells were now being used with telegraph equipment.
1881 - J.A. Thiebaut patented the first HP F2019 battery with both the negative electrode and porous pot placed in a zinc cup.
1881 - Carl Gassner invented the first commercially successful dry cell battery (zinc-carbon cell).
1899 - Waldmar Jungner invented the first nickel-cadmium rechargeable battery.
1901 - Thomas Alva Edison invented the alkaline storage HP Pavilion ZT1100 battery.
1949 - Lew Urry invented the small alkaline battery.
1954 - Gerald Pearson, Calvin Fuller and Daryl Chapin invented the first solar battery.
Alessandro Volta
Biography of Alessandro Volta the inventor of the first practical battery in 1880.

Alkaline Battery
Lew Urry developed the small alkaline battery in 1949. The inventor was working for the Eveready Battery Co. at their research laboratory in Parma, Ohio. Alkaline batteries last five to eight times as long as zinc-carbon cells, their predecessors. This was not a patentable invention, since Volta and others long ago created the principles of batteries.

Solar Battery
A solar battery converts the sun's energy to electricity. In 1954, Gerald Pearson, Calvin Fuller and Daryl Chapin invented the first solar battery. The inventors created an array of several strips of silicon (each about the size of a razorblade), placed them in sunlight, captured the free electrons and turned them into electrical current. Bell Laboratories in New York announced the prototype manufacture of a new solar HP Omnibook XT1000 battery. Bell had funded the research. The first public service trial of the Bell Solar Battery began with a telephone carrier system (Americus, Georgia) on October 4 1955.

The history of photovoltaics includes the discovery of the solar battery. PV is the technological basis for solar power.

On the notebook's battery to maintain a small number of common sense

07:02, 2008-Nov-20 .. 0 comments .. Link

Bought a new battery should be three complete charge and discharge, in order to activate the internal battery of chemicals, so that the battery into the best condition. Usually do not frequently open and close the laptop, or else they will consume a large amount of battery power. If the computer is not a short period of time, it can be in a state of sleep or hang. The use of the Windows power management features, Dell 312-0393 battery power consumption can be reduced to a minimum. Can also download a power management software used to manage power of books, recommended Le Power Center is a free service designed for notebook power management software!
First, the battery charge
In order to improve efficiency and ease of use, in the notebook battery charge is generally used when the fast charge mode, a charge time in the 1.5 to 3 hours. Ni-MH battery current approach to the general charge, and temperature control (that is, to a certain time interval check the battery's temperature rise) or law-ΔV (Ni-MH battery capacity reached 100% before the Dell Latitude D800 battery voltage was gradually increased However, 100% charge capacity, because of its heat through the Dell BAT3151L8 battery cell voltage drop, and so have a drop-ΔV) measured as a result of control of charging on the basis of whether or not to terminate, together with the TCO of control (with temperature Based on the charge to cut off, cut off the temperature of 60 ℃), to ensure the safety rechargeable nickel-metal hydride batteries. Lithium-ion battery chemistry in its decision to charge, first with the constant current charging mode, constant current charge to 4.2V when the (single-core or a few energy-saving power when the parallel core voltage) into the charging voltage, Pressure dropped to 100mA charge current around, stop charging.
Although many notebook computer batteries using the wisdom of the battery technology can be accurately measured and the state of charge of battery life, allow users to use many of the worry, but the Dell Inspiron 8500 battery charge when we should pay attention to the following:
1. Rechargeable batteries should be for the ambient temperature 0 ℃ ~ 45 ℃ temperature scale. The process of charging the battery temperature will affect the charging efficiency and service life, so when conditions permit, the best lithium-ion batteries in 10 ℃ ~ 30 ℃ temperature range for battery charging, so as to achieve the best efficiency of the charge . Ni-MH battery temperature control is the use of the law or law-ΔV to detect whether the battery is full, the experiment showed that: charging the higher the temperature, the more it is not easy to judge whether the battery is full. Therefore, Ni-MH battery charge when the desired temperature in the 10 ℃ ~ 20 ℃ between.
2. If the laptop's AC power adapter is not a great power, rechargeable Dell 8N544 battery , Dell Inspiron 8600 battery, if conditions permit so that the machine should be shut down or in standby mode without any operation. Because the notebook computer power adapter can provide a certain degree of power is, the system load large (such as the use of hard disk drive or load time, and so on) the time allocated to the battery power on the small, it decreases the charge current, the current AC power adapter from the power margin decision. If the battery is less than the current requirements of the charge current, so if things continue this way will affect the battery's working life. Some notebook computers on the statement called for the laptop battery will not operate this is the reason. We can power adapter and notebook computers rated voltage and current power adapter to calculate the margin of power, which decided to charge the battery when the need for shutdown. The method is simpler: To compare the shutdown and shut down both cases, rechargeable batteries used in time, if the difference more, this laptop's battery charge in the best when it shut down.
3. To ensure that the use of your laptop's power adapter match. Inappropriate power adapter may not be fully charged battery, or battery meter can not correctly display the battery power.
Second, the Dell Latitude X300 battery , Dell W0465 battery discharge
1. Can discharge the battery in -20 ℃ ~ 60 ℃ temperature range, preferably at -10 ℃ ~ 45 ℃, because the temperature is below -10 ℃ or 45 ℃ higher than when the battery discharge capacity Will be less than the rated capacity, leading to lower battery performance (with the exception of special applications, the vast majority of laptop users, the ambient temperature is generally not lower than -10 ℃ or higher than 45 ℃).
2. Whether or Ni-MH battery lithium-ion Dell INSPIRON 2650 battery , Dell 1G222 battery, once the battery to the laptop power supply, and so that the best discharge the battery completely before recharging, which will help extend battery life. The so-called "full discharge" the battery is not fully put the power to do, but according to different types of batteries used to power batteries to allow the value of the minimum values to the battery voltage as a basis, such as nickel cadmium, nickel metal hydride batteries single Discharge Dell Inspiron 6400 battery , Dell Inspiron E1505 battery should not be lower than 1.0V, lithium-ion battery power-saving single-core discharge should be an end to 3.0V (should not be less than the minimum 2.7V), otherwise they will damage the battery. Because the notebook computer (or battery) has an internal control to monitor the discharge circuit (it will be based on the battery discharge condition and the work of the current machines to determine whether the battery can continue to work to maintain the machines), so in actual use, we only need to battery The power to put 1% to 5% charge to start worrying about the battery discharge would be excessive. If the practice can not fully discharge each time, then at least every other month to conduct a full battery discharge, as the notebook computer on a regular basis to the full discharge can increase the storage capacity of the battery, extending the battery life of service.
Battery Maintenance
The battery is a kind of material consumption, and its performance over time will gradually reduce. But as long as the proper use, or it could be as much as possible the extension of the life of. So in actual use, to master the maintenance of a number of laptop Dell 2834T battery , Dell 4834T battery and maintenance approach is also very positive. Actual use, we must pay attention to the following:
1. A new Dell GD761 battery put into use, there should be 3 to 5 times the full charge and discharge, in order to activate the battery chemicals, so that the Dell Inspiron 2000 battery 's rated capacity to meet the design for the future lay a solid foundation for normal service. After long-term storage battery re-use, should also be carried out several full charge and discharge, in order to restore the original capacity. Specifically: in the BIOS, turn off the power saving options, then enter the "Control Panel" in the "power management" and "the use of power" in "battery" at the bottom of the 3 options are set to "never . "

And then select the "alert" category, for "lack of battery alarm" and "a serious shortage of battery alarm" two options before the "√" removed, and then close the screen saver, and then to the battery-powered laptops, Prompted battery to 3% to 5%, the screen brightness to a minimum (or close the screen), power up to 0%, and then connected to AC power adapter for charging the Dell KD476 battery, has been sufficient to 100%.

2. Machines do not use without a battery charge state, the machine should be pulled out of the power plug.
3. Do not put batteries to direct sunlight, the battery should not be stored in high-temperature environments, such as the summer's car, and so on, otherwise it would lead to reduced battery performance. According to the nickel-metal hydride batteries and lithium-ion Dell TD347 battery should be kept at low temperature storage properties, they kept in a temperature of -20 ℃ ~ +20 ℃ environment is the best, easiest way is to compare the battery on the refrigerator cold Interior, so as to effectively prevent the deterioration of the characteristics of the battery.
4. When we remove the laptop battery intended to be stored for a long time, Ni-MH battery to full power; lithium-ion battery and storage, according to official data, should ensure that the battery is full of state and a half (that is, about 50% in electricity ), In order to reduce the wear and tear of the battery. If a long period full of power, or fully discharged, the battery will have a negative impact on life expectancy.
5. In order to give notebook computer batteries to extend the duration of power supply, we should also conduct a number of energy-saving settings. The energy-saving notebook computer set up. Have been able to reduce power consumption, mainly because of a computer into the state of energy-saving, closed in a timely manner, that do not require the use of the equipment.
The energy-saving BIOS settings Dell Latitude LS battery: in the BIOS settings, enter the "Power" option in "Power Mode for Battery" select "Maximum Battery Life" (the largest Dell Inspiron 1000 battery mode, that is, energy-saving mode). In addition, some do not have to manually shut down the equipment in order to save energy, such as the closure of the serial, parallel, infrared, and so on. Some BIOS settings can also idle machine shut down automatically after a certain period of time displays, hard disk or standby mode, which can be based on actual need for a corresponding set of (different types of BIOS settings may vary).
Windows in the energy-saving settings: general users, in the Windows system for the management of energy-saving operation may have a better understanding of some simple. "Control Panel", select the "power management" option, "Power Management properties" dialog box, should "use of power" set to "Portable / Laptop" reasonable arrangement "Dell Inspiron 2200 battery , Dell 312-0292 battery" at the bottom "Turn off monitors" and "shut down hard" and "System standby" option 3.

If the battery has been significantly shortened the Dell INSPIRON 2600 battery, then try to use 3 to 5 times the full charge and discharge the battery to restore some capacity. If you are using a Ni-MH battery, you can try IBM's software-specific discharge isbr01ww.exe (This is IBM's software for use nickel-metal hydride battery of the ThinkPad 390 series notebook computers designed by the trial found that a certain general ), This software can be downloaded http://epocn.chouge.com/nbsoft/sbr01ww.exe or ftp://ftp.pc.ibm.com/pub/pccbbs/mobiles/isbr01ww.exe. It should be noted that these methods not only because of frequent discharge as a result of the decline in battery capacity and effective, the service life of the battery-effectiveness of the latter is highly unlikely. Of course, still some way to save, and that is invited to the master cells for batteries.



Common sense notebook batteries

07:01, 2008-Nov-20 .. 0 comments .. Link

With the popularity of notebook computers, notebook battery problems will be more and more books are attention to the family, so often asked that question, I now put my own experience and some of the company's technical staff's experience, take Share out.

First, whether there is a lithium battery memory effect?

Lithium Dell Inspiron 640m battery memory effect is very small, almost to 0.

Second, if the battery trying to put together do not have to, because of how the deal?

Should be filled up to 90% of the electricity, put plastic wrap in the shade.

Third, for the first time must be sufficient enough to charge you 12 hours?

For those who do not have this early battery control circuit of the Ni-MH battery model is applicable, but now has a smart charge-discharge control circuit for the notebook battery is a joke, when a notebook computer Dell Y9943 battery , Dell RC107 battery, the charge current will be automatically cut off , Even if you continue to charge 120 hours, there will not be any change in the state, generally speaking, even if the charge of the slowest machines, 6 hours completely filled, the rest of the "charge" is just a waste of their time. It is time to get the new machines should first get a rechargeable power shine.

Fourth, we know what we have sufficient number of such power?

To give an example, IBM's AC CESS IBM can see there are a number of battery life, we can clearly know the time and battery charge for the first time the state of health. The other books should also have similar features, we look.

Fifth, it is not so direct batteries do not have to do with AC power?

不. The reason is that lithium-ion Dell Latitude D620 battery inside a relatively long period of time if the rest (the so-called relatively static, that is, without electricity or a small amount of battery power. For a long time generally refers to 6 months or so), will be completely lost the function of electrical energy storage (no matter what you use What methods, such as the so-called big charge big release, and even charge more than 12 hours is not good).

Sixth, the battery life in the end is how much?

To tell you, there is no concept of time constraints, the general life of lithium batteries (Remember, life is) is a charge of around 400-500 times lower than the figure of battery quality definitely a problem.

Seven of the new battery is to be activated

In fact, the battery-activated in the factory should have been completed, the notebook battery factory brought a little of the power is natural in order to avoid wear and tear caused damage to the battery. The battery should be activated in the absence of the protection circuit of manner, with a lithium battery protection circuit itself, the design of the circuit block in order to avoid over-charging and discharging of the battery, battery in a general power, charging indicator light Out of the moment, the battery is not in charge of the state, so this time you then plug the charger plugged into the above is no charge for any significance. We can see that the situation of the battery cell is in charge, there is a simple way to determine whether the battery charge in the state, in charge when the Dell 312-0386 battery , Dell PC764 battery , Dell TD175 battery will be emitting a certain amount of heat, when the battery is full after an hour (charger Plug Power is not being pulled down), then you touch the battery, this time you will find that the battery is at room temperature in the state, which is at this time because the battery is no longer a state-of-charge, of course, no heat generated.

Eight, the use of an external power supply when the need to unplug the battery

In fact, you have to look forward to using an external power supply is not the time needed to recharge the batteries, rechargeable batteries have a direct bearing on the number of life, under normal circumstances, the number of lithium battery charging and discharging is fixed, the number of general charging only about 500, most No more than 800. All of us to charge a battery electricity, accordingly, there can be a charge to reduce the number of times. But now many notebook manufacturers have to take into account the vulnerability of the battery, battery on an increase in protection technology, not satisfied with certain conditions will not be charged. Even so, for a long time when you use an external power supply when the computer is recommended that you unplug the battery because the Dell Latitude D820 battery temperature is also one of the enemy, when used in notebook computers would produce a certain temperature, which is very harmful to the battery. Of course, if you own the battery is not sure if I suggest that you put your battery and then pull down the use of an external power supply, because not all batteries have the protection of the circuit. The other is if you have a computer that can control the power to set the charge of the software (for example, when less than 20% of the electricity or other parameters, you can own the battery charge, but the existence of the software and I have not yet determined whether it), then of course you can not unplug the battery.

Nine, can be calibrated to enhance the capacity of the battery it?

The so-called correction, when the actual capacity of the battery and control circuit record is not the same capacity, on a battery charge and discharge depth of the operation, so that the control circuit record, so that the battery close to the actual situation, this is a true performance of the battery capacity The operation rather than enhance the capacity of the key factors here is the actual capacity of the battery if the battery's actual capacity than the control circuit in the capacity to a record high, correction can be made to increase the capacity of the battery looks, if the battery's actual capacity than the control circuits The capacity to a record low, the correction will reduce the capacity of the battery looks, which is many people over the effect of correction of the reasons, keep in mind is correct Dell Latitude D830 battery , Dell MM165 battery to show the true capacity, the elimination of battery and control circuit between the Bias, as demonstrated by the capacity will increase or decrease, this is the battery itself, rather than the state of your correction by the decision. Correction is likely because the battery discharge when the depth of injury, but capacity has been falling.

10, the need for regular battery of correction, once a month put the total charge?

The memory effect of a strong Ni-MH battery, which is an essential task, but lithium batteries, the cycle is too frequent, and lithium batteries did not completely eliminate memory effect, but has been greatly reduced memory effect, if you use the battery is Frequently, you should discharge the Dell YD626 battery to the relatively low (about 10 ~ 15%) rechargeable, but that even if the discharge machines are not open (0 to 1%), belonging to the Li-ion battery for a greater depth of the injury discharge Generally speaking every 2 months to do so once the operation of it. If you use very little battery, so long as every three months the first time this operation can be had.
