50 Using a Battery
You can change the settings for the battery alarms in QuickSet or the
Power Options Properties window. See "Configuring Power Management
Settings" on page 52 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 50.
• Use the Power Management Wizard or the
Power Options Properties
window 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 "Configuring Power Management Settings" on page 52 for information
on conserving battery power.
Power Management Modes
Standby and Sleep Mode
Standby mode (sleep mode in Microsoft Windows Vista™) conserves power
by turning off the display and the hard drive after a predetermined period of
inactivity (a time-out). When the computer exits standby or sleep mode, it
returns to the same operating state it was in before entering standby or
sleep mode.
NOTICE: If your computer loses AC and battery power while in standby or sleep
mode, it may lose data.
To enter standby mode in Windows XP, click Start→ Turn off computer→
Stand by.
