"It was charging too slow. Why does not it charge anymore?"에 답변Our iPad 3G is similar in that we have to turn it off after plugging it in and wait for 10-15hrs before it is fully charged again. Did you ever get your issue resolved?
"Battery not charging at all? Can it be something else?"에 답변On our iPad it doesn't matter the method that you connect it, it still fails to actually charge (still shows charging). Only way we have gotten ours to charge to 100% is to plug it into a charger and turn it off. After about 10-15hrs the iPad can be turned on again and you are greeted with 100% battery life. Any sooner than that and it will show less than 100%.
