ACPI Enabled Yes

This mainboard supports ACPI (Advanced Configuration
and Power management Interface). Use this item to enable
or disable the ACPI feature. ACPI is a power management
specification that makes hardware status information
available to the operating system. ACPI enables a PC to turn
its peripherals on and off for improved power management
especially in portables. It also allows the PC to be turned on
and off by external devices, so that the touch of a mouse or the
press of a key will “wake up” the machine.
