Discharging the Battery Pack
Before you begin a full discharge, disable Hibernation. To disable
Hibernation:
1. Open the Power Options window:
In Windows XP, select Start > Control Panel >
Performance and Maintenance > Power Options >
Hibernate tab.
In Windows 2000, select Start > Settings > Control
Panel > Performance and Maintenance > Power
Options > Hibernate tab.
2. Clear the Enable Hibernation check box.
The notebook must remain on while the battery pack is being
discharged. The battery pack can discharge whether or not you
are using the notebook, but it will discharge faster while the
notebook is in use.
If you plan to leave the notebook unattended during the
discharge, save your work before beginning the discharge
procedure.
If you use the notebook occasionally during the discharge
procedure and have set energy-saving timeouts, expect the
following performance from your system during the
discharge process:
The monitor will not turn off automatically.
Hard drive speed will not decrease automatically while
the notebook is idle.
System-initiated Standby will not occur.
