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’s battery, see
the chapter titled “Batteries and Power Management” in the online Reference Guide.
To check battery status
From the battery charge light
The battery charge light on the front of the notebook shows whether the notebook’s
battery is charging or fully charged—see “Status lights” on page 15.
From the Windows taskbar
The Windows taskbar includes a power icon that provides detailed battery status
information (see Windows Help and Support 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 Power Meter window.
?? Click the power icon to display a menu of the available power schemes.
?? Right-click the power icon to view the options for displaying power information.
From the Windows Control Panel
?? Click Start, Control Panel, Performance and Maintenance, Power Options, then click
the Power Meter tab to see battery status. The Alarms and Advanced tabs provide
additional power-information options.
On the battery
1. Remove the battery from the notebook—see "Step 1: Install the battery" on page 17.
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.
