Notebook Battery Maintenance 8 major misunderstanding

In a notebook computer, the battery is a love-hate interwoven parts, it gives the notebook mobile use of the ability, but compared to constantly working days or even a week of cell phone and MD, notebook battery time is still a cutting, if the cell phone battery can only use 8 hours, will be reviled by thousands of people, But such achievements in the notebook computer has been the pride of the outstanding, to say that the development of the slowest laptop parts, in addition to the keyboard should be the turn of the battery, so that there is a joke:

Intel is supporting new battery technology through investment and technology involvement, "Lithium batteries have been good enough for us in the 1990 's, says Mooly Eden, director of Intel Mobile platform Marketing." The battery improves just like a teenager and a sexual relationship: everyone talks, but nobody does. " "

Battery maintenance has been a hot topic for laptop users, but in fact there are a lot of misunderstanding, in the final analysis from two aspects, one is "thinking does not keep up with Ni-MH battery to lithium battery transformation", another more funny, is from mobile phones, Because the mobile phone is actually the most users of the first access to the use of rechargeable battery equipment, it will take for granted that some of the habits of the phone to the notebook computer.

I'm not going to train most notebook users as experts, that's not necessary, I just want to clarify some of the pitfalls that are easiest to get into, and give the right ideas and practices.

Thinking can't keep up with the battery shift

Misunderstanding one: The notebook computer to buy back and charge three times in order to activate the battery.

Unless you buy a laptop that is in stock for more than a year, otherwise, you do not need to do so, because the current battery batteries in the factory has been activated, and the core in the packaging into a notebook battery after another equivalent to the activation of the test, so you take the hand of the battery, has already been activated, Another three times charge and discharge process is just unnecessary to increase the loss of the battery.

Mistake two: The first charge must be sufficient 12 hours

This is true for early Ni-MH battery models that do not have a battery control circuit. But for today's intelligent battery charging and discharging control circuit of notebook batteries is a joke, when the laptop battery full, the charging current will be automatically cut off, even if you continue to charge 120 hours, the state will not change any more, In general, even the slowest-charging machine, 6 hours is fully filled, the remaining "charge" is only a waste of their time. Instead, when you get the new machine, you should first charge the light.

Myth Three: The battery needs periodic correction, once a month thoroughly recharge.

For a nickel-hydrogen battery with a very strong memory effect, this is a must, but for lithium batteries, this cycle is too frequent, lithium battery although not completely eliminate memory effect, but has greatly reduced the memory effect, if you use the battery is very frequent, then you should discharge the battery to a relatively low (about 10~15%) recharge, But if the discharge to even the machine can not open (0~1%), it belongs to the lithium battery has a greater damage to the depth of discharge, in general, every 2 months to do this operation on it. If you rarely use a battery, you can do it once every 3 months.

Q: Battery is not long, how should be saved?

A: Charge or discharge to about 40%, and then put in the temperature 15~25摄氏度 dry place to save, too high temperature and too low are easy to speed up the battery aging.

Q: The laptop battery will not be removed every time to use power?

A: It doesn't matter, the laptop battery has a protective circuit, full of will not continue to charge

Q: My battery is only a short time now, how to do?

A: If you have been using the battery frequently, this is a battery aging phenomenon, this is unavoidable, you can only consider changing a new battery or changing the battery cell, if your battery is not long, it may cause this phenomenon, this time need to complete the discharge (until no boot), and then full of electricity, Repeat several times to activate the battery.

Q: Can the laptop's power adapter be universal?

A: No, there are three obstacles, the first is the use of different manufacturers of notebook computers, such as IBM are 16V,COMPAQ mostly 18.5v,sony part of the model is 19.5V, are not uniform. The second is that different laptops need different currents, from 2a~5.4a, small machines need less current and larger machines. The third is that each manufacturer notebook computer power adapter interface is different, it is difficult to general. As a result, there is no power adapter available for all laptop computers.

Q: How should the newly bought machine be recharged? How should the battery be maintained?

A: Lithium (ion) batteries need to maintain a certain electromotive force to maintain the activity of their internal chemical substances. So in charge of the time to do full full put, in general, the first three times can charge about six hours of time, the time is tight, the electricity charge to 100% good. Use in order to avoid the point charge, less than 10% time to charge, not to run out, so that the battery instead of injury, but also at a higher than 60% when try not to charge. Batteries that are not used for long periods of time apply to about 50% of the electricity in a dry environment at room temperature.

Q: Why does my IBM laptop always use the battery a little less brightly than when it is powered?

A: This is an IBM random power management default setting that is designed to save power: If you don't like this, you can select the LCD project in the IBM System control software ThinkPad Configuration utility, and then change the brightness from normal to high. The display options in the BIOS also have the same settings. The purpose of this is to save electricity.

Q: First use of batteries, the first three times need to charge 12 hours?

A: This is completely unnecessary, because today's notebook computers have a sound power management electricity

Road and charge management system, when the battery reaches saturation, the control circuit will automatically switch to the circuit breaker State,

So even if the time is long and no effect.

Q: In order to prevent the memory effect, to use electricity to recharge it?

A: It is not necessary to discharge the battery before each charge, and it is harmful. Practice proves that the depth of the battery

The degree of discharge will make the useful life of unnecessary reduction, it is recommended that when the battery is only about 10% can be charged

The electricity. It is best not to charge when the battery is still more than 30%, because the memory effect

exist more or less in reality.

Q: How to extend the use of your laptop as much as possible when you use it?

a:1, low screen brightness, LCD screen is a large power consumption, reduce the brightness can effectively prolong the use of time.

2, open SpeedStep and Powerplay and other power-saving functions, now the notebook processor and display chips have to reduce the operating frequency and voltage to prolong the use of time function, open the appropriate options can greatly prolong the battery use time.

3, the use of hard disk and optical drive spin down software. such as Nero Drivespeed, powerbooster and other software can reduce the optical drive, hard drives, such as the speed of the drive, can also effectively reduce the power consumption of the notebook computer.

4, the use of standby, hibernation and other functions. When you are not using your computer for a long time, you can put your laptop on standby or hibernate, which saves power and prolongs your computer's life.

Misunderstanding four: The correction can improve the battery capacity

The so-called correction, is when the actual capacity of the battery and control circuit in the record capacity is not the same, carry out a deep charge and discharge operation on the battery, let the control circuit refresh the record, make it close to the actual condition of the battery, this is a performance of the actual capacity of the battery rather than lifting capacity, where the key factor is the real capacity of the battery, If the actual capacity of the battery is higher than the recorded capacity in the control circuit, the correction can make the battery appear to increase the capacity, if the actual capacity of the battery is lower than the recorded capacity in the control circuit, then the correction will make the battery looks less capacity, which is why many people argue about the effect Keep in mind that the correction is the actual capacity of the battery present, eliminate the deviation between the battery and the control circuit, as to whether the displayed capacity will increase or decrease, which is the state of the battery itself, not your correction. It is possible that the battery is significantly reduced due to deep discharge damage during correction.
