Installation
This connector supports the ATX case-mounted Power Switch, which in turn
supports System Suspend function. When the BIOS sets the Power Button function
to “Suspend”, the system can be set to the suspended mode once you push the
power switch for no longer then 4 seconds. If the power switch is pushed down for
over 4 seconds the system will be totally Power Off. When this BIOS setting sets to
“Instant-off”, then Power Switch function work as regular power switch.
Power/Sleep LED (2-pin)
This header can be connected to a 2-color LED that will light yellow or green when
the computer is in “Suspend” or “Normal” operation.
Speaker Connector (J19, 4-pin, Optional)
It is used to drive a chassis-mounted speaker if desired. Or this header will be
removed and replaced with an integrated Buzzer.
