 Battery Meter
The battery meter indicates the remaining battery charge. To check the 
battery meter, double-click the 
 icon in the notification area. 
Check the Battery Health
You can check battery health by using the Battery Meter in Dell QuickSet. 
For information about QuickSet, right-click the QuickSet icon in the 
notification area, and then click Help.
Low-Battery Warning
 
NOTICE: 
To avoid losing or corrupting data, save your work immediately after a 
low-battery warning, then connect the computer to an electrical outlet. If the 
battery runs completely out of power, Sleep state begins automatically.
A pop-up window warns you when the battery charge is approximately 
90 percent depleted. The computer enters Sleep state when the battery 
charge is at a critically low level.
You can change the settings for the battery alarms in Dell QuickSet or the 
Power Options window (see "Configuring Power Management Settings" on 
page 47).
Conserving Battery Power
To conserve battery power on your portable computer, do any of the 
following:
Connect the computer to an electrical outlet when possible; battery life is 
largely determined by the number of times the battery is used and 
recharged.
Configure the power management settings using either Dell QuickSet or 
Microsoft Windows Power Options to optimize your computer’s power 
usage (see "Configuring Power Management Settings" on page 47). 
Use the Sleep power state when you leave the computer unattended for 
long periods of time (see "Using the Sleep Power State" on page 48).
Configuring Power Management Settings
You can use Dell QuickSet or Windows Power Options to configure the 
power management settings on your computer.
