Tablet wont turn on
My daughter has had this tablet for 2 years. It was working just fine, we turned it off and put it on the charger for the night. Now I cannot get it to turn back on. I have googled "quick fix" which was "hold down the power button for 30secs" didnt work....."hold down power, volume up and down all at the same time for 30seconds"....still nothing. Advice?!
