Product Description

1.10.2.1
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.
1.10.2.2
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 8 on page 30 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.
1.10.2.3
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.
1.10.2.4
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.
1.10.2.5
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.
1.10.2.6
Wake from S5
When the RTC Date and Time is set in the BIOS, the computer will automatically wake
from an ACPI S5 state.
1.10.2.7
Wake from Consumer IR
CIR activity wakes the computer from an ACPI S3, S4, or S5 state.
