Hardware Support

CAUTION

Ensure that the power supply provides adequate +5 V standby current if LAN wake
capabilities and Instantly Available PC technology features are used. Failure to do so
can damage the power supply. The total amount of standby current required depends
on the wake devices supported and manufacturing options.

The board provides several power management hardware features, including:
• Power connector
• Fan headers
• LAN wake capabilities
• Instantly Available PC technology
• Wake from USB
• PME# signal wake-up support
• Wake from PS/2 devices
LAN wake capabilities and Instantly Available PC technology require power from the
+5 V standby line.

NOTE

The use of Wake from USB technologies from an ACPI state requires an operating
system that provides full ACPI support.

1.13.2.1 Power Connector

ATX12V-compliant power supplies can turn off the system power through system
control. When an ACPI-enabled system receives the correct command, the power
supply removes all non-standby voltages.

When resuming from an AC power failure, the computer returns 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.
