The most common situation is that the laptop is running at full speed when using battery, the current is too large to result in automatic protection. For example, to capture the contents of DVD discs from the drive into the mobile hard disk, both host and peripheral are consuming power, it is likely to make current beyond the battery standards of protection, in this case do not panic, as long as to disconnect peripherals to wait about 10 minutes and then reboot.

There is also a common situation that using laptop computer in a hot environment and high-load operation using the battery, so that the ambient temperature plus the heat generated by the battery self-discharge may exceed the battery protection circuitpreset temperature. Encountered such a situation should remove the battery and placed in a cooler place (remember not to put into the refrigerator for frozen!), After half an hour should be back to normal. The damage of high temperature is relatively large to the lithium battery, less than a last resort should be avoided to high-load use the laptop in high-temperature environment.

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

Many models also have Windows discharge functions. This can save time, emendation while working. Battery Calibration should not be too often, the frequently deep discharge can shorten the battery life, it is recommended two to three months to do it once.
