Hi, my iPad is not charging through the wall charger it says 10% and it shows no indication that its charging (or not) when it's plugged in, it just stays the same. I think it's charging though, because when the battery depleted and it shows the battery and the lightning bolt sign (telling you to charge it,) it recognizes when I plug it in and just shows the lightening bolt (meaning its being powered.) Any thoughts? Should I just take it in to the Apple store for a new one? Thanks!
