I had done nothing differently than I always do. I turn it on play a few games each night then power down. Only this time when I turned it on, it just had oh about 6 or 8? horizontal lines of chinese with some numbers. One row was highlighted and I could move the highlight up or down with the pressing of the volume button. Then it showed vol up, vol dwn, and pwr. which would disappear as I pressed each one with no other effect. At one time there was what looked like maybe a timer counting down? I was pressing all combinations of the pwr and vol. buttons and different things came on the screen, but always either chinese or numbers, except for the pwr, vol. up, and vol. dwn list. Nothing I could do would turn it off. Even the pwr. and volume down button together did nothing.
Finally, I just put it face down and left it. The next day the battery was dead. I plugged it into the charger, pushed the power button, and it came on normal. So, I hope that was a one time occurrence and not going to happen more often.
