19) System Power LED Lead (3-1 pin PWRLED)
This 3-1 pin connector supports the system power LED, which lights when the
system is powered on and blinks when it is in sleep or soft-off mode.
20) Keyboard Lock Switch Lead (2-pin Keylock)
This 2-pin connector supports the case-mounted key switch to permit keyboard
locking.
21) System Warning Speaker Connector (4-pin SPEAKER)
This 4-pin connector supports the case-mounted speaker.
22) System Message LED Lead (2-pin MSGLED)
This lead 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
received. This function requires an ACPI OS and driver support.
23) System Management Interrupt Lead (2-pin SMISW)
This connector permits 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 preceding figure) connects to the case-
mounted suspend switch.
24) ATX Power Switch / Soft-Off Switch Lead (2-pin PWRSW)
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 or ON
and SOFT OFF, depending on your BIOS or OS setting. Pushing 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 supports 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.
