You can view the battery charge status by completing the 

following procedures.
If you move the mouse pointer over the battery icon in the 

system tray of the Desktop, the remaining battery charge is 

displayed.

A battery is an expendable supply, so when using it over a long 

time, the capacity/battery life is shortened. If the battery life is 

reduced to under half of its initial time, we recommend purchasing 

a new battery.
When not using the battery for a long time, store the battery after 

charging it to 30-40% of its capacity. This extends the battery life 

time.

Press the 

 + 

 keys on the keyboard to decrease the LCD 

brightness to extend the battery usage time.

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.
