Recalibrating the battery
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. You should also
recalibrate the battery periodically to maintain
the accuracy of the battery gauge.
To recalibrate the battery:
1 Connect the AC adapter, then turn on your
notebook.

screen, press F2. The BIOS Setup utility
opens.
3 Open the Advanced menu.
4 Highlight Battery Auto Learning, then
select Enabled by pressing the spacebar.
5 Open the Exit menu, then highlight Exit
Saving Changes and press E
NTER.
6 Select Ye s , 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.
7 Press ESC. The battery charge indicator
now displays an accurate battery charge. If
the battery charge indicator does not show
an accurate charge, contact Gateway
