common Laptop Battery-related issues summary

Q: the laptop battery a long-term need, it should be how to preserve?
A: Charge or discharge to about 40%, and then placed in temperature of 15 to 25 degrees Celsius dry preservation, the temperature is too high and too low are easy to accelerate cell aging.

Q: The battery does not remove the books to each power supply will you?
A: It does not matter, the laptop battery(inspiron 1520 battery) protection circuit again, full of will not continue to charge.

Q: My battery is now only a very short period of time, how should I do?
A: If you've been in the frequent use of the battery, then it belongs to cell aging, which can not be avoided, you can only consider the change a new battery or if the replacement batteries batteries; If you do not have battery long-term, may also lead to this phenomenon, this time need to completely discharge (up to fail to boot up) and then full power, repeated several times to activate the inspiron 1520 battery.

Q: laptop universal power adapter can do?
A: No, there are three obstacles, the first is the notebook computer manufacturers use various different voltage, such as IBM are 16V, COMPAQ mostly 18.5V, SONY part of the model is 19.5V, are inconsistent. The second is different from the needs of current laptop is different from the 2A ~ 5.4A have a small machine needs a smaller current, big machine in the latter case. The third is the various manufacturers notebook power adapter interfaces are different, it is difficult general. Therefore, at present do not yet common to all the notebook power adapter .

Q: How should the new machine bought charging it? How do I maintain the battery?
A: Lithium (ion) battery vostro 1500 battery is the need to maintain a certain electromotive force to maintain its internal chemical activity. Therefore, to achieve full charge when the full release, in general, the first three can be a period of about six hours of charge time will be tight, like electric charge to 100%. To avoid the use of point charge, less than 10% of the time to charge a timely manner and not to be exhausted, so that the battery but there is injury; also higher than 60%, also try not to charge. A long time without battery applied to about 50% of electricity at room temperature and dry environment preservation.

Q: Why does my IBM laptop is always in use when the vostro 1500 battery power than with the low brightness when a file?
A: This is the IBM default settings for random power management is aimed at energy-saving:), if you do not like it, you can control software in IBM's ThinkPad Configuration Utility, select LCD project, then changed to High brightness from Normal.
