Modem Connector: Jp4 - Acorp 4S651M Manual

Chapter 1
SMI Suspend Switch Lead (G-BUN) (Disabled)
This allows the user to manually place the system into a suspend
mode of Green mode. System activity will be instantly decreased
to save electricity and expand the life of certain components
when the system is not in use. This 2-pin connector (see the
figure) connects to the case-mounted suspend switch. If you
do not have a switch for the connector, you may use the "Turbo
Switch" instead since it does not have a function. If you want
to use this connector, the "Suspend Switch" in the Power
Management Setup of the BIOS SOFTWARE section should
be enabled.
Reset Switch Lead (RST)
The connector can be connected to a reset switch. Press this
reset switch to restart system.
