To check battery status

From the battery status light

You computer has a battery status light—see “Status Lights” on page 17.

From the Windows taskbar

The Windows taskbar can display a power icon that provides detailed battery status information (see Windows Help for details). The icon looks like a battery when AC is not connected.

•Place the pointer over the power icon to display the remaining battery charge. This value is shown as either a percentage of charge remaining, or as time remaining.

•Double-click the power icon to open the Battery Meter window.

From the Windows Control Panel

•Click Start, Control Panel, Performance and Maintenance, Power Options, and then click the Power Meter tab to see the battery status. The Alarms and Advanced tabs provide additional Windows’ power-information options.

On the battery

1.Remove the battery from the computer—see “Step 1: Install the battery” on page 19.

2.Press the contact pad on the side of the battery. The number of lights that turn on indicates the remaining charge (each light represents 20% of a full charge).
