To check battery status

From the battery status light
Check the battery status light on the notebook.
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
Select Start > Control Panel > Performance and Maintenance > Power Options, then
select the Power Meter tab to see the battery status. The Alarms and Advanced tabs
provide additional power-information options.
On the battery
1. Remove the battery from the notebook. See "Getting Started with Your
Notebook" in this guide.
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 percent of a full charge).

To respond to a low-battery warning

The notebook automatically alerts you when the battery power drops to a critically
low level. The notebook first emits a high-pitched beep or displays a warning
message. Then, if you do not restore power within a short time, the notebook goes
into Hibernation.
