If you use the computer occasionally during the discharge procedure and have set energy- saving timeouts, 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 when the computer is idle.

System-initiated hibernation will not occur.

To fully discharge a battery pack:

1.Right-click the Power Meter icon in the notification area, at the far right of the taskbar, and then click Adjust Power Properties.

– or –

Access the Power Schemes tab by selecting Start > Control Panel > Performance and Maintenance > Power Options > Power Schemes tab.

3.Set the 4 options to Never.

4.Click OK.

5.Disconnect the computer from its external power source, but do not turn off the computer.

6.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 battery light is turned off and the computer shuts down.
