2.11 External Suspend Switch Lead (SMI) (J3)
This allows the user to manually place the system into a suspend
mode or "Green" mode when the system is not in use. System activity
is decreased to save electricity and prolong the life of certain compo-
nents. The 2-pin connector connects to the case-mounted suspend
switch. If you do not have a switch for the connector, you may use the
"turbo switch", because it does not have any other function. SMI is
activated when it detects a "short to open" moment. Therefore, leaving
it shorted will not cause any problems. It may require one or two
pushes
depending on the position of the switch. Wake-up can be controlled
by settings in the BIOS, but the keyboard will always allow wake-up.
(The SMI lead cannot wake up the system.) If you want to use the
SMI connector, the "Suspend" switch in the Power Management
Setup of the BIOS software should be on the default setting "Enable".
