Well lookey here, I login to research startup/shutdown controllers and I come across this thread. Kristian, as you may have figured out, your power switch is simply something that shorts out when depressed. In davis449's case, both ends of the power switch was connected to the 2 wires of the modem port. Plug in an rj11 phone cable, short the other ends out, boom, you got power on. But this still requires manual interaction. What most of the controllers offered offer fancy options that laptop users do not require, but are fundamentally a relay. Essentially, when powered, the relay closes shorting the circuit. This device is all that is needed for our purposes, which I am in the midst of tinkering with.
