Hi, I'm trying to work out what is going on with my ipod shuffle (4th Gen) and was hoping someone could shed some light on it for me - I've searched and searched forums and can't find anyone else reporting a similar fault, but really don't want to have to go to the macstore if possible as its a long way away! So, if I plug the ipod into the laptop, it charges fine. All the lights are doing what they should be, and if I then play it immediately after being charged, it plays for hours, no problem. The problem is, if I then fully charge it, take it out of the computer and leave it (switched off), the next time I use it, it runs for about 10 minutes and then goes flat. I've tried resetting it twice now and its making no difference. Is there something else I can do, or is this just broken?
