What should I do if my laptop battery suddenly loses power?

Most notebook batteries are protected circuits, when the notebook battery temperature is too high or the discharge current is too large, may be due to exceed the laptop battery protection circuit action standards, and the battery automatically forced to power off the problem.

The most common scenario is that the laptop runs at full speed when using the battery, causing the current to be too large to be automatically protected. For example, from the CD-ROM drive to capture the contents of the DVD disk into the mobile hard drive, when the host and peripherals are in a large amount of power consumption, it is possible to make the current exceeds the protection of the battery standards, this situation does not need to panic, as long as the disconnect peripheral waiting for 10 minutes

It is also common for laptops to operate at high battery load in a hot environment, so that the ambient temperature plus the heat generated by the battery's own discharge may exceed the preset temperature of the battery protection circuit, especially when the high frequency P4 machine is running at high temperature. This situation should be taken out of the battery placed in the lower temperature (remember not to put the refrigerator frozen!), should be able to return to normal after half an hour. High temperature damage to lithium batteries is relatively large, less than the last resort should try to avoid the high temperature in the environment to use laptop computers.
