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.
1Disconnect the AC power adapter after turning off the computer.
2Restart your computer and press the F2 button when the Samsung logo appears, to start the BIOS Setup.
3Move to the Boot > Smart Battery Calibration item using the direction keys and press <Enter>.
4Highlight Yes in the Battery Calibration Confirmation window and press <Enter>.
The Battery Calibration function is activated and the battery is forcefully discharged. To stop the operation, press the (Esc) button.
This operation requires 3~5 hours depending on the battery capacity and the remaining battery charge.
