I bought this 4th Gen. iPod 20GB refurbished back in December and it worked fine for about a month or more, then it started needing to be reset quite a bit. What will happen is, I'll be listening to music, turn it off, then go to turn it back on an hour or so later and it won't come on. I'll reset it, then it'll work fine. It's really random. Sometimes it works fine, sometimes it doesn't. It seems to do this the most, though, when listening to podcasts. I could be hallucinating that part, though. I sent it back to Apple because I thought the battery was dying about 2 or so weeks ago. I charged it all the way up one night, then the next day, it wouldn't come on, so I reset it and the battery was completely dead. Apple sent it back and said that the battery was fine. I'm still having the problem where it won't come on, though the battery does seem to be working okay. What do you guys think the problem is? Oh yeah, I've restored it 2 or 3 times with no success.
