21. Message LED Lead (2-pin MSG.LED)
This indicates whether a message has been received from a fax/modem. The
LED will remain lit when there is no signal and blink when there is data transfer
or waiting in the inbox. This function requires ACPI OS and driver support.
22. 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.
23. 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. 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.
