The following illustration is for items 1723.
17) System Power LED Lead (3-1 pin PWRLED)
This 3-1 pin connector connects the system power LED, which lights when the
system is powered on and blinks when it is in sleep mode.
18) Keyboard Lock Switch Lead (2-pin KEYLOCK)
This 2-pin connector connects to the case-mounted key switch to allow keyboard
locking.
19) System Warning Speaker Connector (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker. Two sources
(LINE_OUT and SPEAKER) will allow you to hear system beeps and warnings.
Only SPEAKER will allow you to hear system beeps before the integrated audio
has been properly initialized.
20) System 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 received.
This function requires an ACPI OS and driver support.
21) 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
connects to the case-mounted suspend switch.
22) ATX Power Switch Lead (2-pin PWRSW)
The system power is controlled by a momentary switch connected to this lead.
Pressing the button once will switch the system between ON and SOFT OFF.
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 systems power.
23) 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 to prolong the life of the systems power supply.
