Low-Battery Warning

NOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning, and 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. See "Configuring Power Management Settings" on page 42 for information about accessing 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 41 for more information about standby and hibernate modes.

•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>. See "Configuring Power Management Settings" on page 42 for more information.

NOTE: See "Battery Performance" on page 39 for more information on conserving battery power.
