Use 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. Turn off the computer and disconnect the AC power.
2. Turn on the computer and press <F2> to enter into System Setup.
3. Select Smart Battery Calibration in the Boot Menu,
and press <Enter> to start.
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 and the battery is completely
discharged, connect the AC power adaptor to fully recharge the battery.
Power Saving Effect
This shows the relative battery use time for each power mode. The more
effective the power saving, the longer the graph will appear.
When Running a Game or Multimedia Application
A game or multimedia application may not work smoothly in Maximum
Battery Saving Mode.Using this is recommended when the AC adapter is
connected or in Normal or higher modes.
