All of the answers I read about this subject did not pan out for me. Since I had my P500 for some 5 years already, I figured the reason for the Power Button not starting up the camera would more than likely be a mechanical issue. And not something to do with faulty chargers or batteries. I was 100% correct about this. Through extensive experiementation, I found the square battery was not fully seating itself in the slot at the bottom of the camera due to weakened springs which likely stretched out over the hundreds of times I inserted these batteries. While pressing against the bottom of the battery and the Start Button simultaneously, I noticed the camera went on. Soon as I released pressure on the battery, the camera shut off. Thus, there was not enough pressure on the square battery to press against the gold contacts at the bottom of this cavity. So how did I fix this problem? I ....

Simple: I cut and folded a small strip of index card about 4 pieces thick and carefully placed this between the graphics card and battery but under the battery latch. It will be a very tight fit as you hold this lid down while sliding the locking mechanism closed. But at least now my camera goes on and off without fail. MAYBE SOME ENGINEERS AT NIKON SHOULD ADDRESS THIS PROBLEM BOTH WITH EXISTING AND FUTURE UNITS! I sure hope this helps you guys out as I spent countless hours trying other methods out there until I stumbled upon this solution. Happy holidays!
