Table 10 lists the devices or specific events that can wake the computer from specific states.

Table 10. Wake-up Devices and Events

These devices/events can wake up the computer…

…from this state

 

 

LAN

S1, S3, S4, S5 (Note)

Modem (back panel Serial Port A)

S1, S3

 

 

PME# signal

S1, S3, S4, S5 (Note)

Power switch

S1, S3, S4, S5

 

 

PS/2 devices

S1, S3

 

 

RTC alarm

S1, S3, S4, S5

 

 

USB

S1, S3

 

 

WAKE#

S1, S3, S4, S5

 

 

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.

1.14.2Hardware 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 Desktop Boards D925XCV and D925XBC provide 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.
