III. INSTALLATION
10. Power LED Lead (TB_LED)
The system power LED lights when the system's power is on.
11. SMI Suspend Switch Lead (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). If you want to use this connector,
"Suspend Switch" in the Power Management Setup of the BIOS SOFTWARE
section should be on the default setting of Enable.
12. Reset Switch Lead (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.
13. Keyboard Lock Switch Lead & System Power LED (KEYLOCK)
This 5-pin connector connects to the case-mounted keyboard lock switch for
locking the keyboard and also to connect the system power LED. The system
power LED lights when the system is powered on and blinks in sleep mode.
14. Speaker Connector (SPEAKER)
This 4-pin connector connects to the case-mounted speaker.
