8. IDE Activity LED (IDE_LED)
This connector connects to the hard disk activity indicator light on the case.
9. System Power LED (CON1)
This 2-pin connector lights the system power LED when the motherboard has
power. Works the same as the next System Power LED. See the figure on the
next page.
10. Keyboard Lock Switch Lead & System Power LED (CON1)
This 5-pin connector connects to the case-mounted key switch for locking the
keyboard and also the system power LED. The system power LED lights
when the motherboard has power. See the figure on the next page.
11. 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 elec-
tricity and expand the life of certain components when the system is not in use.
This 2-pin connector (See the figure on the next page) 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 set-
ting of Enable.
