Before beginning a full discharge, disable Hibernation. To disable
Hibernation:
-
Open the Power Options window:
-
In Windows 2000, click Start, Settings, Control
Panel, Performance and Maintenance, Power
Options, and the Hibernate tab.
-
In Windows XP, click Start, Control Panel,
Performance and Maintenance, Power Options, and the
Hibernate tab.
- 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 the notebook is in use, but will discharge faster while the
notebook is in use.
-
If planning to leave the notebook unattended during the
discharge, save work before beginning the discharge
procedure.
-
If using the notebook occasionally during the discharge
procedure and energy-saving timeouts are set, expect the
following performance from the 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.
Follow these steps to fully discharge a battery pack:
-
Select the power icon on the taskbar, or access the Power
Schemes tab:
-
In Windows 2000, click Start, Settings, Control
Panel, the Power Management icon, and the Power Schemes tab.
-
In Windows XP, click Start, Control Panel,
Performance and Maintenance, the Power Options icon,
and the Power Schemes tab.
-
Make a note of the two settings in the Plugged In column and
the two settings in the Running on Batteries column so that they can be reset after the calibration.
-
Use the drop-down lists to set the four options (two in each
column) to Never.
-
Click OK.
-
Disconnect the notebook from the external power source, but
do not turn off the notebook.
-
Run the notebook on battery power until the battery pack is
fully discharged. The battery light begins to blink when the
battery pack has discharged to a low-battery condition. When
the battery pack is fully discharged, the battery light turns off
and the notebook shuts down.
