Low-Battery Warning

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 42).
