Recalibrating the battery
If your notebook unexpectedly goes into Sleep 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 batteries periodically to maintain the accuracy of the
battery gauges.
To recalibrate the battery:
1
Connect your notebook to AC power and let the battery
charge completely.
2
Disconnect the AC power and restart your notebook.
3
Completely discharge the battery.
4
After the battery is completely drained, reconnect your
notebook to AC power.
5
Charge the battery completely until the battery status
indicator turns blue.
Important
Do not interrupt the battery recalibration process. If recalibration is
interrupted, you must start the process over again.
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 .
