I didn’t charge my iPad for a very long time. So when I plug it in, it doesn’t make the beeping sound when it’s being charged. And it won’t turn on or show the the low battery symbol. But my computer recognizes it. Also the home button and sleep/wake button don’t work too well. Thanks!
if your computer recognizes the ipad then your battery is fine. It’s more likely that the LCD is busted. But it’s going to be very hard to tell without more testing.
