Power Management Features

Power management is implemented at several levels, including:
•
Advanced Configuration and Power Interface (ACPI)
•
hardware support
•
•
ACPI
If the motherboard is used with an ACPI-aware operating system, the BIOS can provide
ACPI support. ACPI gives the operating system direct control over the power
management and Plug and Play functions of a computer. The use of ACPI with this
motherboard requires the support of an operating system that provides full ACPI
functionality. ACPI features include:
•
Plug and Play (including bus and device enumeration)
•
Power management control of individual devices, add-in boards (some add-in boards
may require an ACPI-aware driver), video displays, and hard disk drives.
•
methods for achieving less than 30-watt system operation in the Power On Suspend
sleeping state, and less than 5-watt system operation in the Suspend to RAM
sleeping state
•
a Soft-off feature that enables the operating system to power off the computer
•
support for multiple wake events (see Wake Up Devices and Events section on page

•
support for a front panel power and sleep mode switch
