20) ATX Power / Soft-Off Switch Lead (2-pin PWR.SW)
The system power is controlled by a momentary switch connected to this lead.
Pushing the button once will switch the system between ON and SLEEP or ON
and SOFT OFF, depending on your BIOS or OS setting. 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 system’s power.
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.
