Power
If you use the computer occasionally during the discharge process
described below and energy-saving time-outs have been disabled,
expect the following performance from your system during the
discharge:
■Any unsaved work from your current session will be lost
when the battery pack is fully discharged and the computer is
shut down.
■The system will not turn off a connected optional monitor.
■The system will not decrease hard drive speed while the
computer is idle.
■System-initiated hibernation will not occur.
To fully discharge the battery pack:
1. Disable hibernation. To disable hibernation:
Select Start > Control Panel > Performance and
Maintenance > Power Options > Hibernate tab. Then clear
the Enable hibernation check box.
2. Display the settings on the Power Schemes tab. To access
the Power Schemes tab:
Select Start > Control Panel > Performance and
Maintenance > Power Options > Power Schemes tab.
3. Record all settings in the Plugged in column and all settings
in the Running on batteries column, so you can reset them
after calibration.
4. Use the drop-down lists to set each item in both columns
to Never.
5. Click OK.
6. Disconnect the computer from the external power source,
but do not turn off the computer.
7. Run the computer 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 computer is shut
down.
