Wake-up Devices and Events

Table 9 lists the devices or specific events that can wake the computer from specific states.
Table 9. Wake-up Devices and Events
These devices/events can wake up the computer...
LAN
Modem (back panel Serial Port A)
PME# signal
Power switch
PS/2 devices
RTC alarm
USB
WAKE# signal
Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On
will enable a wake-up event from LAN in the S5 state.
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 connectors
•
LAN wake capabilities
•
Instantly Available PC technology
•
Resume on Ring
•
Wake from USB
•
Wake from PS/2 keyboard
•
PME# signal wake-up support
•
WAKE# signal wake-up support
LAN wake capabilities and Instantly Available PC technology require power from the +5 V
standby line.
Resume on Ring enables telephony devices to access the computer when it is in a power-managed
state. The method used depends on the type of telephony device (external or internal).
