Actually it covers all three functions, on/off/sleep. Usually it must
be held down for 4 seconds to turn off the system. A good thing if you have
a button pushing two year old wandering through your work area.

Thanks, the one thing i did not do is hold that front button in for
anything longer than a quick push. I'll crap if i was just not holding
this button in long enough to wake up the power supply, probably
wishfull thinking,
but i'll give it a try !
