POWER SUPPLY CONTROL (J9H1,J9K2)

When used with a power supply that supports remote power on/off, the Advanced/RH motherboard can turn off the system power via software control (“soft-off”). The Powerman utility supplied for Windows 3.1x allows for soft-off as does the shutdown icon in Windows 95 Start menu. The system BIOS will turn the system power off when it receives the proper APM command from the OS. For example, Windows 95 will issue this APM command when the user selects the “Shutdown the computer” option. Note that APM must be enabled in the system BIOS and OS in order for the soft-off feature to work correctly. Power supplies that support “soft-off” connect to the motherboard via the 3-pin “PWS CNTRL” connector, which is a Molex 2695 connector featuring a security latch for reliability. In order for the system to recognize the presence of a “soft-off” power supply, the supply must tie pin 3 of the PWS Control connector to ground.
