III. INSTALLATION
9. Turbo LED lead (CON1)
The motherboard's turbo function is always on. The turbo LED connection is
labeled here but the LED will remain constantly lit while the system power is
on. You may wish to connect the Power LED from the system case to this lead.
See the figure below.
10. SMI suspend switch lead (CON1)
This allows the user to manually place the system into a suspend mode or
"Green" mode where 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 below) connects to the case-mounted
suspend switch. If you do not have a switch for the connector, you may use the
"Turbo Switch" since it does not have a function. SMI is activated when it
detects a short to open moment and therefore leaving it shorted will not cause
any problems. 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 this connector, "Suspend Switch" in the POWER MANAGEMENT
SETUP of the BIOS software should be on the default setting of Enable.
11. Reset switch lead (CON1)
This 2-pin connector connects to the case-mounted reset switch for rebooting
your computer without having to turn off your power switch This is a
preferred method of rebooting in order to prolong the life of the system's power
supply. See the figure below.
12. Keyboard lock switch lead & Power LED lead (CON1)
This 5-pin connector uses 3-pins for the case-mounted key switch for
locking the keyboard to prevent unwanted users. Two of the 5-pins are used
for the case-mounted power LED. See the figure below.
13. Speaker connector (CON1)
This 4-pin connector connects to the case-mounted speaker.
