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.
You can make the actual battery charge and the remaining
charge display 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 the
actual product depending on the computer model and
driver version.

3

4
The Battery Calibration function is activated and the
battery is forcefully discharged. To stop the operation,
press the Esc key.
This operation requires 1-3 hours depending on the battery
capacity and the remaining battery charge.
