Just picked it up and pushed the bottom button and nothing happened. I tried hitting every button and nothing, hooked it up to the wall charged, the computer, nothing. Finally I just held the bottom button and the top button and finally a little silver apple showed up on the screen after about 5+ seconds of holding both buttons down. Then my custom backgound showed up with the slider and everything appears normal.....wierd though. Battery was at half charge. Has this happened to anyone?
