2.5.13 ACPI Connector: J2
When used with an ATX-compliant power supply that supports remote power
on/off, the CPU card can turn off the system power through software control.
To enable soft-off control in software, advanced power management must be
enabled in the Setup program and in the operation system. When the system BIOS receives
the correct APM command from the operating system, the BIOS turns off power to the
computer.
With soft off enabled, if power to the computer is interrupted by a power outage or
a disconnected power cord, when power resumes, the computer returns to the power state it
was in before power was interrupted (on or off).
