Product Description
1.10.1.2 Wake-up Devices and Events
Table 14 lists the devices or specific events that can wake the computer from specific
states.
Table 14. Wake-up Devices and Events
These devices/events can wake up the computer…
LAN
…from this state
S1, S3, S4, S5 ^(Note)
Modem (back panel Serial Port A)
PME# signal
Power switch
PS/2 devices
RTC alarm
S1, S3
S1, S3, S4, S5 ^(Note)
S1, S3, S4, S5
S1, S3
S1, S3, S4, S5
USB
S1, S3
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.
1.10.2 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
LAN wake capabilities and Instantly Available PC technology require power from the
+5 V standby line. The sections discussing these features describe the incremental
standby power requirements for each.
