I bought a DPAD7 7" tablet for my son for Christmas. I set it up and played with it before wrapping and he used it for a full day after he opened the present yesterday. Today, all of a sudden, it won't turn on. I have used the reset button on the back, held the power button, and tried mutiple combinations of buttons, power, reset, home, etc. Still nothing. It was fully charged over night and was working this morning for a while. I know that it wasn't the highest quality tablet and would probably not last forever; but, I expected more than a day. Does anyone have suggestions?
