My girlfriend has the Droid Razr Maxx HD. Shes has it for about a month and a half a few days ago it was acting funny so i had her turn it off and then it wont turn back on. I have tried the power+down volume method does absolutly nothing. But when i put it on the charger it shows the green charger light but nothing else at all. Any suggestions?
Power button on my R Maxx (not HD) began to fail. But unlike your phone, plugging it into the charger did get it to go on. But once it cycled to black screen it stayed there. Moto replaced the phone. Nuisance moving from one unit to another. But when I did a full hard factory reset before returning the phone, strangely the power button acted much better. But then the phone had been wiped clean so you may not want to venture there.
