Using Battery Power
For information about how your notebook regulates 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 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 resembles a battery when AC
power 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.
• Select 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 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).
