ACPI enables the direct control by the operating system over the power management and Plug
and Play functions of a computer. ACPI requires an ACPI-aware operating system, such as

ACPI features include:
• Plug and Play and Advanced Power Management (APM) functionality as here
contained in the BIOS Setup Utility.

boards may require an ACPI-aware driver), video displays, and hard disk drives.

less than 30-watt computer operation in the Power On Suspend sleeping state,
and less than five-watt operation in the Suspend to Disk sleeping state.
• A soft-off feature that enables the operating system to turn off the computer.
