Larry, forget this power supply crap (remember what I said in the previous post). While it is "possible", it is very unlikely and not what the indications here indicate.

You are on the right track with the power button. The 4400/4200/4500/15000 etc are notorious for the power button going bad. What most often happens is the button gets pressed too hard and the little switch seperates from the circuit board it is soldered to. Check this first!
