The Battery Calibration function is activated and the battery
is forcefully discharged. To stop the operation, press the <Esc>

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.
