Power Management Features
Power management is implemented at several levels, including:
• Advanced Configuration and Power Interface (ACPI)
• Hardware support:
⎯ Power connectors
⎯ Fan connectors
⎯ Suspend to RAM (Instantly Available PC technology)
⎯ Wake from USB
⎯ Wake from PS/2 keyboard/mouse
⎯ PME# wakeup 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 the desktop board requires an operating system that
provides full ACPI support.

power connectors.
