Recalibrating the battery(ies)
Important
Do not interrupt the battery recalibration process. If recalibration is interrupted, you must start the process over again.
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 your battery(ies). You should also recalibrate the battery(ies) periodically to maintain the accuracy of the battery gauges.
To recalibrate the battery(ies):
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 Advanced menu.
4Highlight Battery Auto Learning, then select Enabled by pressing the spacebar.
5Open the Exit menu, highlight Exit Saving Changes, then press ENTER.
6Select Yes, then press ENTER.
The battery recalibration process begins and a screen opens showing you the progress. The entire process takes 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.
Important
If, after completing this procedure, the battery charge indicator still does not show an accurate charge, contact Gateway Customer Care at the location shown on the Customer Care label. For more information, see “Gateway contact information” on page 3.
