Calibrate Your Samsung Laptop Battery

The importance of calibrating batteries

   The battery life may be reduced when the battery is repeatedly charged and discharged within a short period of time. To restore the actual battery level and remaining battery display, you need to fully discharge the battery using the Smart Battery Calibration feature and then charge it again.

IMPORTANT: If your laptop will only turn on when it is plugged in, then your battery is damaged and you need to replace it.

When do you need to calibrate your laptop?

Step 1:

First save and close all applications/software you are currently using.

Disconnect the AC adapter.

NOTE: You will not be able to run Smart Battery Calibration if the AC adapter is connected.

Step 3:

Restart the laptop and press the F2 key when the SAMSUNG logo appears to start the system setup program.

Using the left or right arrow key, select Startup.
