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.
By default, a pop-up window warns you when the battery charge is approximately 90 percent depleted.
You can change the settings for the battery alarms in QuickSet or the Power Options Properties window.
See "Configuring Power Management Settings" on page 15 for information about accessing QuickSet or
the Power Options Properties window.
Conserving Battery Power
Perform the following actions to conserve battery power:
• Connect the computer to an electrical outlet when possible because battery life is largely determined
by the number of times the battery is used and recharged.
• Place the computer in standby mode or hibernate mode when you leave the computer unattended for
long periods of time (see "Power Management Modes" on page 14).
• Use the Power Management Wizard
to select options to optimize your computer’s power usage. These
options can also be set to change when you press the power button, close the display, or press <Fn><Esc>.
NOTE: See "Power Management Modes" on page 14 for more information on conserving battery power.
