• 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.
