Table 8. Wake-up Devices and Events

These devices/events can wake up the computer… …from this state

LAN S1, S3, S4, S5

NOTE

The use of these wake-up events from an ACPI state requires an operating system

that provides full ACPI support. In addition, software, drivers, and peripherals must

fully support ACPI wake events.

1.12.2 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# signal wake-up support

• Wake from Consumer IR

LAN wake capabilities and Instantly Available PC technology require power from the

+5 V standby line.
