Well, I've never sold anything for Apple in a store, have never worked for Apple or worked for an Apple Store or worked for a retail establishment selling Apple products or worked in the service industry servicing Apple products. I'm simply a long-term Apple user from back in 1984 ... :-) ... and have had a lot of experience (from a user standpoint) of many different Apply products.
What I post is from experience and also from the standpoint of answering "directly" some of the things that some people say, which are patently and obviously wrong and I see it, strictly from a user standpoint and from long experience.
None of those comments are to say that someone "in particular" is "not" having a problem. That's not what is being said. There are answers for any problem when an iPad is not working ... and Apple Support "has the answer" for you. Or the Apple Store and the Genius at the Genius Bar has the answer for you. I'll guarantee you ... that if you go to either Apple Support or the Apple Store, you will get the correct and proper answer in order to get an operating and running iPad - whatever it takes to get there. But, you do have to go through the steps.
And again ... whatever I give for suggestions for "fixing" an iPad is NOT to replace Apple Support and it's NOT to replace the Apple Store and its customer service. THAT is your main stop and that is where you should be going - and NOT "users helping other users" - if you're not getting your answers here. Your answer is at Apple Support, and they will do whatever it takes to get you a functional and running iPad.
This particular forum is for those kinds of people who "love to fiddle" with their devices and just love to test and go through all the steps and see how it functions and if they can fix it themselves. If you are not "that kind of person" then don't stop in here ... go to Apple Support where they help their customers!
