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 48 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 50 for more information.

NOTE: See "Battery Performance" on page 45 for more information on conserving

battery power.
