14. Message LED Lead (2-pin MLED)
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 mail waiting in the inbox. This function requires ACPI OS and driver support.
15. System Management Interrupt (SMI) Lead (2-pin SMI)
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).
16. Speaker Connector (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker.
17. ATX Power Switch / Soft Power Switch (2-pin PWR)
The system power is controlled by a momentary switch connected to this lead.
Pushing the button once will switch the system between ON and SLEEP. Push-
ing 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.
18. System Power LED (3-pin PLED)
This 3-pin connector connects the system power LED, which lights when the
system is powered on and blinks when it is in sleep mode.
19. 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 in order to prolong the life of the system’s power supply.
