This exact thing happened to my wife's M yesterday as well. All I did to get it back up and running was take it out to the car (as we were out to lunch) and plug it into the charger and it rebooted all on it's own. Never touched any buttons or anything. Strange why that happened though. She was just trying to open up Song Pop and it froze and she tried to power it off and reboot and this happened.
I was the originator of this post several months ago. I have not had this problem again. This is one awesome phone with a lot of good capabilities. Just got the jellybean upgrade earlier this week. Very satisfied except for the first week hiccup.
My RAZR M did the same thing only it ran out of juice and refused to charge or reboot while plugged into the wall. I tried holding the buttons but no joy. I decided to try the car charger and it worked! It started taking the charge and after a minute or two it started right up. The wall charger didn't have enough punch to get the battery to accept the charge at such a low state.
Sorry for my English

Finally signed up because I have to thank everyone for fixing my phone today.
I've been waiting 40 years -well not really 40 years, it was 39 years earlier this summer- for a phone call and it should be happening any day now and when I turned on my phone this morning it lite up but wouldn't turn on. I hit the power button again and that was it, it would not come back up.
I checked to see when the verizon store would open and being Sunday it opens at 11 just when we were to go to an anniversary party.
I held the power and vol button for at least a minute and when I released them it came back to life. To say I was elated would be an understatement.
This site has been my source to fix and get operational answers for my razr.
