What if laptop battery has a problem

Most models have a battery protection circuit, when the battery temperature is too high or when the discharge current is too large, probably because it beyond the battery protection circuit standard that occur the problem of power failure automatically.

The most common situation is that the use of laptop battery when running at full speed causing excessive current automatic protection. For example, remove the content from the DVD in CD-ROM into the hard disk, then the host and peripherals are consuming a lot of power, it is possible that the current exceed the battery standard of protection, in which case do not panic, as long as disconnect peripherals to wait for about 10 minutes and then re-boot.

Another common situation is the laptop in a hot environment, high-load operation using the battery, so that the ambient temperature plus the heat generated by the battery self-discharge battery protection circuit may exceed the preset temperature, this situation may occur especially in high frequency P4 machine after high speed operation at high temperatures. Encountered such a situation you should remove the battery and place it in a cooler place (remember not placed in the refrigerator to frozen!), after half an hour it would be back to normal. For high temperature can damage lithium battery a lot, less than not you should avoid use the laptop in a hot environment and work high load.

In order to maintain the BIOS state, there are many laptop battery with calibration option, in simple terms, this functionality would charge laptop battery fully and then discharged completely , then recharge, so not completely discharged for long-term, cumulative errors caused some corrective action. However, please note that the BIOS correction takes a long time, you’d best do that before go to bed.

Many models also have discharge functions in Windows. This can save time, you can do that while working. Battery calibration should not be too frequent, frequent deep discharge will shorten battery life, we recommend two to three months once.

If all the ways do not work, you need a new laptop battery.
