Connectors

18)System Power LED (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.

19)Keyboard Lock Switch Lead (2-pin KEYLOCK)

This 2-pin connector connects to the case-mounted key switch to allow key- board locking.

20)System Warning Speaker Connector (4-pin SPEAKER)

This 4-pin connector connects to the case-mounted speaker. You may leave this disconnected if your motherboard has an onboard buzzer which can replace the chassis speaker. When connected, you will hear system warnings through both sources. NOTE: Some sound cards allow you to connect to the system speaker signal so that the warnings can be heard and adjusted through your multimedia system.

21)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 transfer or waiting in the inbox. This function requires ACPI OS and driver support.

22)System Management Interrupt Switch Lead (2-pin SMISW)

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 con- nects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the “Turbo Switch”. SMI is activated when it detects a short to open moment and therefore leaving it shorted will not cause any prob- lems. This may require one or two presses 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).
