Extending the Battery Usage Time

Decreasing the LCD Brightness

Press the Fn + keys on the keyboard to decrease

the LCD brightness to extend the battery usage time.

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.

Disconnect the AC power adapter after turning off

the computer.

Restart your computer and press the F2 button when

the Samsung logo appears, to start the BIOS Setup.

Move to the Boot > Smart Battery Calibration item

using the direction keys and press <Enter>.

Highlight Yes in the Battery Calibration

Conrmation 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.
