I have a polaroid android tablet 4.0.4 PMID705 and it has not been turning on in about 5 days! Someone dropped my tablet and now I don't know what happened. I tried to hold the power button for 12 seconds; didn't work. I don't have volume buttons. I've tried charging it but it hasn't worked either. It somehow has to be on because I think that it would've already turned on. Help please? :'(
