We are having the same issue with nabi as well. Fully charged, when I try to turn it on I get the "powered by android " then the screen goes dark. Very disappointed. I had bought 2 nabi's for both of my girls. I saw online lot of other people have the same issue. I think it's just a defect in this product. They keep telling everyone that their is something wrong with the battery. Well in my case I have tried 3 chargers and several different sockets, the light is green and still won't turn on. So it's not the problem with the charger, it's nabi. Going to try and see if their Tech support is any helpfully. Their online answers sucks. Never going to recommend anyone to buy nabi. Regular tablets and Ipads works much better, never had any issues with my iPad or my android tablet. Nabi sucks..... what a waste of money....
