Power Management
Your computer supports APM ( Advanced Power Management) and
ACPI (Advanced Configuration and Power Interface) for power
management. The power management feature allows you to reduce the
power consumption for energy saving.
With an ACPI-compliant operating system such as Windows 2000 and
Windows XP, power supply to different computer components is
controlled on an as-needed basis. This allows maximum power
conservation and performance at the same time.
In general, Windows’ power management works in this way:
What…
When…
Power to the hard disk is turned off
When the hard disk has been idle for a
set period.
Power to the display is turned off
When the display has been idle for a set
period.
When the entire system has been idle
for a set period.

“Suspend-to-Disk” function, which is equivalent to Windows’ Hibernation function. (See
“Power Menu” in Chapter 5 for more information.)
