I'm not sure what the problem could be. It was working fine last night. The battery was probably down to about 60% or something like that, but nowhere near dead. I didn't plug it in or anything, but I'm sure it wouldn't be drained. Anyway, I just took it out of my bag this morning at work and it won't power on at all. I've tried holding down the home button and power button together and separately and nothing is working. I've plugged it into the wall and into my computer and neither did anything for it. It has been plugged into the wall for about 30 minutes now and it still won't power on. I'm lost for a solution to this. What could have gone wrong? It wasn't dropped or wet or cold or hot or anything. It just sat on the table in the front room till this morning when I put it in my backpack and went to work. ???
