Freeze then Blank screen
I can't see this mentioned on any other thread so here goes.
Yesterday I plugged my One into the griffin charger in my car, the phone froze and when I pressed the power button the screen went blank.
It looked to me that I had cooked the power circuits as nothing I did brought any response from the phone.
Anyway the good news, I left it plugged into the charger and this morning the notification light was green and it powered on as normal.
The phone seems to be working fine now, and as I thought it was goosed, I am a lucky boy.
This is not the same as the phone being discharged problem mentioned in another post,but the solution seems to have been the same.
