LAN Wake Capabilities
The board’s LAN wake capabilities enable remote wake-up of the computer through a
network. The LAN subsystem network adapter monitors network traffic at the Media
Independent Interface. The board supports LAN wake capabilities with ACPI in the
following ways:
• By Ping
• By Magic Packet
Upon detecting the configured wake packet type, 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 S1 or S3 state.
NOTE
Wake from USB requires the use of a USB peripheral that supports wake from USB.
Wake from PS/2 Device
PS/2 keyboard activity wakes the computer from an ACPI S1, S3, S4, or S5 state.
However, when the computer is in an ACPI S4 or S5 state, the only PS/2 activity that
will wake the computer is the Alt + Print Screen key combination or the Power key
available only on some keyboards.
PME# Wakeup Support
When the PME# signal is asserted on the PCI bus, the computer wakes from an ACPI
S1, S3, S4, or S5 state.
WAKE# Signal Wakeup Support
When the WAKE# signal is asserted on the PCI Express bus, the computer wakes from
an ACPI S1, S3, S4, or S5 state.
Wake from Serial Port
Serial port activity wakes the computer from an ACPI S1 or S3 state.
