Managing System Power

Managing System Power Managing System Power Managing System Power
In the Windows XP operating system environment, your notebook manages its power resources using the
Advanced Configuration and Power Interface (ACPI) while the system is powered on using AC or battery
(DC) power. ACPI enables the operating system to manage the power given to each attached device and to
turn off a device when not in use.
Take advantage of the opportunity to manage power on your system to:
Minimise battery drain.
Preserve the life of your notebook.
Save time. When you return from that urgent call or meeting, you don't have to reboot, just press the
Power button to resume system operation.
Windows XP Operating System Power Options Properties
In Windows XP operating system, most ACPI power management settings are controlled through Windows
Power Options Properties, not through the BIOS Setup utility, unless otherwise noted. To access Windows
Power Options Properties, go to Start, Control Panel, select Performance and Maintenance, and click on
Power Options.
The Power Options Properties are broken down as follows:
