1.13.1 ACPI

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 D815EGEW board requires an operating
system that provides full ACPI support. 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 15-watt system operation in the power-on/standby sleeping
state.
•
A soft-off feature that enables the operating system to power-off the computer.
•
Support for multiple wake up events (see Table 10 on page 34).
•
Support for a front panel power and sleep mode switch. Table 8 lists the system states based
on how long the power switch is pressed, depending on how ACPI is configured with an
ACPI-aware operating system.
