Using Battery Power
For information about how your notebook regulates its power consumption,
and how you can manually reduce power consumption and extend the life of
the notebook battery, see the “Batteries and Power Management” chapter in the
Reference Guide on the Documentation Library CD included with your notebook.
To check battery status
From the battery status light
Check your notebook battery status light.
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 select 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 notebook. See the “Getting Started with Your
Notebook” chapter 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).
