Displaying Charge Information on the Screen

To display battery charge information on the screen, use the Power meter feature of the operating system:

Select Start > Control Panel > Performance and Maintenance icon > Power Options icon > Power Meter tab.

or

Select the Power meter icon in the system tray.

To display the Power meter icon in the system tray:

1.Select Start > Control Panel > Performance and Maintenance icon > Power Options icon > Advanced tab.

2.Select the Always Show Icon On The Taskbar check box.

3.Select the OK button.

Most charge displays report battery status in both percent and time:

The percent indictes the amount of charge remaining in the battery pack.

The time indicates the approximate running time remaining on the battery pack if the battery pack continues to provide power at the current level. For example, the time remaining will decrease if you start playing a DVD and will increase if you stop playing a DVD.

Most charge displays identify battery packs by location:

Location 1 is the notebook battery bay.

Location 2 is the optional travel battery.

In some displays, a lightening bolt icon may be displayed beside a battery pack location. This icon indicates that the battery pack is being charged.
