I have had an iPod Photo for just over 3 years. The other day, it acted strangely while it was playing. It would play fine, but the screen would freeze. Music was playing just fine in a playlist, but no ability to navigate. It could be fixed by just restarting the unit, but it happened 2 or 3 times in an hour. Then, a day or two later, I got a Sad Mac when I turned it on, then nothing. It will no longer turn on. I've hooked it up to the wall adapter, and USB, but nothing. All of the fixes on the forums I've read assume the iPod will turn on, and mine will not. I know that the battery can go out, and I have used it heavily for 3 years, so it wouldn't surprise me that I need a new battery, however, I want to get some opinions before I go down that path. I would hate to buy a new battery only to find out it doesn't solve the problem. Is anyone familiar with what happens when a battery fails? Any other ideas of what may have gone wrong? I've tried the "smacking" technique, and all the other fixes I could find. The iPod never made any strange noises, and only gave me the error one time before shutting off for good. Thoughts?
