It's not just a ground, the line that brings up the power is a momentary
switch, so a longish (about 1/2 second) pulse would do it. That would
make it easier for you to set it up so you *could* turn it off if you
actually did want to. Of course, if you did turn it off, and used this
pulse idea, the next power fluctuation would turn your PC back on ...
kinda inverted behavior!
