ASUS P4SGL-MX Motherboard 1-19
• System Warning Speaker Lead (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker and allows you
to hear system beeps and warnings.
• System Message LED Lead (2-pin MLED)
This 2-pin connector is for the system message LED that indicates receipt of
messages from a fax/modem. The normal status for this LED is ON, when
there is no incoming data signal. The LED blinks when data is received. The
system message LED feature requires an ACPI OS and driver support.
• System Management Interrupt Lead (2-pin SMI#)
This 2-pin connector permits switching to suspend mode, or “Green” mode, in
which system activity is instantly decreased to save power and to expand the
life of certain system components.
• Reset Switch (2-pin RESET)
This 2-pin connector connects to the case-mounted reset switch for rebooting
the system without turning off the power switch.
• ATX Power Switch / Soft-Off Switch Lead (2-pin PWRBTN)
This connector connects a switch that controls the system power. Pressing
the power switch turns the system between ON and SLEEP, or ON and
SOFT OFF, depending on the BIOS or OS settings. Pressing the power
switch while in the ON mode for more than 4 seconds turns the system OFF.
