Hardware Support
The board provides several power management hardware features, including:
Wake from Power Button signal
Instantly Available PC technology
LAN wake capabilities
Wake from USB (S3,S4 only)
WAKE# signal wake-up support
Wake from S5.for button only
Note:
The use of Wake from USB from an ACPI state requires an operating system that provides full ACPI support.
•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.
•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 off on single colored.) When signaled by a wake-up device or event, the system
quickly returns to its last known wake state. The use of Instantly Available PC technology requires
operating system support and drivers for any installed Mini PCI Express add-in card.
•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.
•Wake from USB
USB bus activity wakes the computer from an ACPI S3, S4 states.
Note:
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
•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.
•Wake from S5
When the RTC Date and Time is set in the BIOS, the computer will automatically wake from an ACPI S5
