Checking the Battery Charge
The following features provide information on the battery charge:

Dell™ QuickSet Battery Meter
If Dell QuickSet is installed, press <Fn><F3> to display the QuickSet
Battery Meter. The Battery Meter displays status, battery health, charge level,
and charge completion time for the battery in your computer.
For more information about QuickSet, right-click the QuickSet icon in the
taskbar, and click
Help.
Charge Gauge
By using the charge gauge on the battery, you can check:
• Battery charge (check by pressing and releasing the status button)
• Battery health (check by pressing and holding the status button)
The battery operating time is largely determined by the number of times it is
charged. After hundreds of charge and discharge cycles, batteries lose some
charge capacity—or battery health. That is, a battery can show a status of
“charged” but maintain a reduced charge capacity (health).
Check the Battery Charge
To check the battery charge, press and release the status button on the battery
charge gauge to illuminate the charge-level lights. Each light represents
approximately 20 percent of the total battery charge. For example, if the
battery has 80 percent of its charge remaining, four of the lights are on. If no
lights appear, the battery has no charge.
