Charge Gauge
By either pressing once or pressing and holding the status button on 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.
Check the Battery Health
NOTE:
You can check battery health in one of two ways: by using the charge gauge on the battery as described
below and by using the Battery Meter in Dell QuickSet. For information about QuickSet, right-click the
the taskbar, and click Help.
To check the battery health using the charge gauge, press and hold the status button on the battery
charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition, and more than
80 percent of its original charge capacity remains. Each light represents incremental degradation. If five
lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the
battery. See "Battery" on page 140 for more information about the battery operating time.
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, hibernate mode begins
automatically.
A pop-up window warns you when the battery charge is approximately 90 percent depleted. The
computer enters hibernate mode when the battery charge is at a critically low level.
You can change the settings for the battery alarms in QuickSet or the Power Options Properties window.
See "Configuring Power Management Settings" on page 63 for information about accessing QuickSet or
the Power Options Properties window.
