If the switching power supply used is an ATX-compliant
power supply, remote power on/off is supported and the
system’s power can be turned off through software control.
This feature is called soft-off control.
Soft-off control allows your computer to automatically go
back to the power state (on, off, or suspend) after being
interrupted either by power outage or by disconnection of
power cord. To enable this feature, your system’s
advanced power management must be enabled both in
BIOS setup utility and in the operating system.
