Managing Power 3-7
Power Management
Your computer supports 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 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 ...
