Recharging the Battery Pack
Ä
CAUTION: After calibrating the battery pack, re-enable hibernation.
Failure to re-enable hibernation may result in a complete battery drain
and potential data loss. To re-enable hibernation:
1. Select Start > Settings > Control Panel > Performance
and Maintenance > Power Options > Hibernate tab.
2. Select the Enable hibernation check box.
3. Select Apply.
To recharge the battery pack:
1. Connect the notebook to external power until the battery pack
is fully recharged. (The battery light on the notebook will
then be turned off.)
You can use the notebook while the battery pack is
recharging but the battery pack will charge faster if the
notebook is off.
2. If the notebook is off, turn it on when the battery pack is fully
charged and the battery light is turned off.
3. Select Start > Control Panel > Performance and
Maintenance > Power Options > Power Schemes tab.
4. Refer to the settings you recorded earlier. Re-enter the
settings that you recorded for the items in the Plugged In
column and the Running on Batteries column.
5. Select OK.
