Specifications
18 CUW-AM User’s Manual
17) Message LED Lead (2-pin MLED)
This indicates whether a message has been received from a fax/modem. The
LED will remain lit when there is no signal and flash when there is data re-
ceived. This function requires an ACPI OS as well as application and driver
support.
18) Keyboard Lock Switch Lead (2-pin KLOCK)
This 2-pin connector connects to the case-mounted key switch to allow key-
board locking.
19) System Management Interrupt Lead (2-pin EXSMI)
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.
20) System Warning Speaker Connector (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker.
21) 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 system’s power supply.
22) System Power LED Lead (3-1 pin PLED)
This 3-1 pin connector connects the system power LED, which lights when the
system is powered ON and flashes when it is in standby (suspend) mode.
