External ATX control Power Connector: CN24
When used with an ATX-compliant power supply that supports remote power on/off, this product 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 “Last State” of BIOS setup (POWER> After Power Failure) setting 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).
