Managing System Power (Windows XP)
In the Windows XP environment, your Versa 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 Versa.
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 Power Options Properties
In Windows XP, 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
