Laptop battery problems with how to do? Teach you two strokes

Most machines are all kinds of battery protection circuit, when the battery IBM ThinkPad A20 Battery temperature is too high or when the discharge current is too large, probably because the battery protection circuit moves beyond the standard, and thus causing the battery power automatically force the issue.

The most common situation is that the use of laptop computer battery is running at full speed when the current is too large to result in automatic protection. For example, from the drive to capture the contents of DVD discs into the mobile hard disk, when a large number of both host and peripheral power consumption, is likely to make current standards of protection beyond the battery IBM ThinkPad A20M Battery, in which case do not panic, as long as the Disconnect peripherals to wait about 10 minutes, you can reboot.

There is also a common situation is that laptop computers 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, which is particularly high frequency P4 machines in high-temperature environment may occur after high-speed operation. Encountered such a situation should remove the batteries placed in a cooler place IBM ThinkPad A21M Battery (remember not to put refrigerator frozen!), After half an hour should be back to normal. High temperature for the lithium battery damage is relatively large, less than a last resort and should be avoided in high-temperature environment, the use of high-load laptop.

In order to maintain the BIOS state, a lot of notebook computers that have the battery calibration option, simply speaking, this function will be the notebook's battery is full and complete discharge to no electricity, and then re-filled, so for a long time not completely discharge the accumulated error caused by the role of a certain correction. However, please note the correction in the BIOS spent rather IBM ThinkPad R60 Battery a long time, if you do this, preferably before going to sleep.

Many models also have Windows, discharge functions. This can save time, while working will be corrected. Battery Calibration will not be too frequent, often the depth of discharge is to bring the battery life shortened, it is recommended two to three months to do it once.
