LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the 5 V standby line for the power supply must be capable
of delivering adequate +5 V standby current. Failure to provide adequate standby
current when using this feature can damage the power supply.
LAN wakeup capabilities enable remote wake-up of the computer through a network.
The LAN subsystem monitors network traffic and upon detecting a Magic Packet*
frame, it asserts a wake-up signal that powers up the computer.
Wake from USB
NOTE
Wake from USB requires the use of a USB peripheral that supports wake from USB.
USB bus activity wakes the computer from an ACPI S1 state.
Wake from PS/2 Keyboard/Mouse
PS/2 keyboard/mouse activity wakes the computer from an ACPI S1 state.
PME# Wakeup Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI
S1 or S5 state.
