Battery Calibration

If you charge/discharge the battery repeatedly for only a short time, the battery use
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 same by discharging the battery completely using the Battery
Calibration function, and then recharging it again.
1. Disconnect the AC power adapter after turning off the system.
2. Restart your computer and press <F2> to enter BIOS setup.
3. Using the arrow keys, highlight Smart Battery Calibration in the Boot menu. The
Battery Calibration function is activated and the battery is discharged forcibly.
This operation requires 3~5 hours depending on the battery capacity and the
remaining battery charge.
4. When the calibration process is complete, recharge the battery fully.
