Conserving Battery Power - Dell Precision PP05XA Quick Reference Manual

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. If two batteries are installed, the low-battery warning means that
the combined charge of both batteries 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" in your User's Guide for information about accessing QuickSet or
the Power Options Properties window.
