1.12.2.1 Power Input
When resuming from an AC power failure, the computer may return to the power state it was in
before power was interrupted (on or off). The computer’s response can be set using the Last
Power State feature in the BIOS Setup program’s Boot menu.
1.12.2.2 Instantly Available PC Technology
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM)
sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is
off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a
wake-up device or event, the system quickly returns to its last known wake state. Table 9 on
page 33 lists the devices and events that can wake the computer from the S3 state.
The use of Instantly Available PC technology requires operating system support and drivers for
any installed PCI Express add-in card.
1.12.2.3 LAN Wake Capabilities
LAN wake capabilities enable remote wake-up of the computer through a network. The LAN
subsystem monitors network traffic at the Media Independent Interface. Upon detecting a Magic
Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer.
1.12.2.4 Wake from USB
USB bus activity wakes the computer from an ACPI S3, S4, and S5 states.
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.12.2.5 WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S3,
S4, or S5 state.
1.12.2.6 Wake from S5
When the RTC Date and Time is set in the BIOS, the computer will automatically wake from an
ACPI S5 state.
