I got a refurbished iPod Nano toady, and it doesn't work. I plugged it in for about an hour while I was putting music on and it won't turn on now. It worked right afterward, for about 10 minutes before I turned if off. It had been plugged in to my computer for about 10 minutes now, and I'm not getting any response; not even a charging logo. Should I contact Apple or just wait overnight to see if the battery is dead?
