23. System Management Interrupt Lead (2-pin SMI)
This allows the user to manually place the system into a suspend mode or “Green”
mode where system activity is decreased to save electricity and expand the life
of certain components when the system is not in use. This 2-pin connector con-
nects to the case-mounted suspend switch. If you do not have a switch for the
connector, you may use the “Turbo Switch”. SMI is activated when it detects a
short to open moment and therefore leaving it shorted will not cause any prob-
lems. This may require one or two presses 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, set “Suspend Mode” under Power Management Setup of
BIOS SETUP section to the preferred time after which the system must go into
suspend mode when you press the switch.
24. ATX Power Switch / Soft Power Switch (2-pin PWR.SW)
The system power is controlled by a momentary switch connected to this lead.
Pressing the button once will switch the system between ON and SLEEP or ON
and SOFT OFF depending on the “PWR Button” setting under Power Manage-
ment Setup of BIOS SETUP section. Pressing the switch while in the ON mode
for more than 4 seconds will turn the system off. The system power LED shows
the status of the system’s power.
25. Reset Switch Lead (2-pin RESET)
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 to prolong the life of the system’s power supply.
26. System Power LED (3-1 pin PWR.LED)
This 3-1 pin connector connects the system power LED, which lights when the
system is powered on and blinks when it is in sleep mode.
27. Keyboard Lock Switch Lead (2-pin KEYLOCK)
This 2-pin connector connects to the case-mounted key switch to allow key-
board locking.
28. System Warning Speaker Connector (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker. You may leave this
disconnect as this motherboard has an onboard buzzer which can replace the
chassis speaker. When connected, you will hear system warnings through both
sources.
NOTE: Some sound cards allow you to connect to the system speaker signal so
that the warnings can be heard and adjusted through your multimedia system.
