Recalibrating the battery
If your notebook unexpectedly goes into Standby mode while you are using
it but the battery charge is not low, you may need to recalibrate the battery.

To recalibrate the battery:

1Connect the AC adapter, then turn on your notebook.
2As soon as it starts and you see a startup screen, press F2. The BIOS Setup
utility opens.
3Open the Power menu.
4Highlight Battery Calibration, then select Enabled by pressing the spacebar.
5Open the Exit menu, then highlight Exit Saving Changes and press ENTER.
6Select Yes , then press ENTER.
The battery recalibration process begins and a screen opens showing you
the progress. The entire process will take several hours.
When the recalibration has finished, the message “Press [Esc] key to exit”
appears.
7Press ESC. The battery charge indicator now displays an accurate battery
charge. If the battery charge indicator does not show an accurate charge,
contact Gateway Technical Support.
Important Do not interrupt the battery recalibration process. If
recalibration is interrupted, you must start the process over
again.
