Changing battery: not so difficult.

問題

Once upon a time, my iPod stop working. It was unable to play music, to recharge, to sync. So I thought that changing battery was a good solution.

修理

I follow the guide, in 30 minutes i've opened my device and changed the battery. IT WORKS. Maybe.

Battery icon was red, so I connected iPod to my Mac to recharge and sync, all seems to be ok. After a few hours I've unplugged it and the battery icon was still red... So I decided to leave it playing music to use all the battery's power for doing a complete charge cycle but now my iPod is fully discharged and won't charge again.

%#*@ logic board. Start to thinking that I have to replace it.

Or not? Maybe the new battery is faulty.

Battery or logic board? Waiting for suggestions.
