Yeah, mine is a similar problem. My 5th gen 80 got replaced back in Oct 09 for the "push the corner down in the right bottom corner to get the ipod sound to come back on". They send me a replacement 80 gig 5th gen and almost 4 months later I am have similar to your problem. When I try and sync with pc, I get nothing, no boxes to inform problem, nothing. after about 10 to 15 seconds it starts to charge. Same with the wall charger. Now I call Apple and they give me the same run around with it's way out of warranty! And then the guys hangs up on me. Atleast I can still listen to the music on it. Can't update or add anymore music. I really am thinking on a Zune!!
