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 your battery.
You should also recalibrate the battery periodically to maintain the accuracy
of the battery gauge.
To recalibrate the battery:
1
Disconnect the AC adapter
2
Turn on your notebook.
3
As soon as it starts and you see a startup screen, press F2 . The BIOS Setup
utility opens.
4
Open the
Power
menu.
5
Highlight
Smart Battery Calibration
, then press E
NTER
. When prompted, start
the recalibration program.
6
After the battery has been fully discharged and your notebook has turned
itself off, re-connect the AC adapter and fully recharge your battery.
Recharging may take several hours. After the battery finishes recharging,
the battery meter displays the accurate battery charge. If the battery meter
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.
