I had my tablet since my last birthday and I accidentally hit it with my elbow when I went to sit down on my bed, an it just turned off to a black screen. I just figured it turned off, but when I tried to turn it on, it didnt do anything, I tried dto charge it, but I can't tell if it is charging because of this problem! I tried googling it but one button combination worked for a while the last time this happened and now the combination doesn't work! I need help to fix this, I really want to use my tablet!
