My phone worked this morning, then I shut it down to charge it with the automotive charger from Motorola.  I tried to start it and nothing happened.  I have read all of the posts about holding down the power and the - (minus) volume button and also the + (plus) volume button and nothing  happens.  I then tried to plug it not the wall socket and nothing happens, I do not  even get a sustained white light.  It flickers when I plug it in then goes off.  I have an old Razr Maxx and it will boot up but will not import my contacts from the SD card.  Help
