Using the Battery Calibration Function
When charging/discharging the battery repeatedly for a short time
only, the battery usage time may be reduced by the difference
between the actual battery charge and the remaining charge
display.
In this case, the actual battery charge and the remaining charge
display will be the same by discharging the battery completely
using the Battery Calibration function, and then recharging it
again.
The screen images and terms may differ from actual product
depending on the computer model and driver version.
