SPC-8450-LVA
ATX power control Connector: CN18
When used with an ATX-compliant power supply that supports remote power on/off, the CPU board 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.
