13. CN13: AT Power ON/OFF Button Connector
This connector is used to connect a chassis power On/Off button using an adapter cable.
This connector is closely related to JP1 configuration. The use of this connector is briefed as
follows:
1. Using ATX power: CN13 connects to a power switch, and the JP1 jumper should be
left open.
2. Using AT power: The pins on JP1 are shorted by a jumper cap. The reason why
JP1 should be shorted is because the AMD Southbridge is
designed without the consideration for a power button signal and
the shorted JP1 provides a hardware feedback to initiate the
system.
