Samsung NP455R4JE 사용자 설명서

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.

The screen images and terms may differ from actual product 

depending on the computer model and driver version. 

  Disconnect the AC power adapter after turning off the 

computer.

  Turn the computer back on, and press the F2 key to enter the 

Setup screen.

  Select Advanced > Smart Battery Calibration.
