Hey Folks,
I solved the problem by getting another charging cable. They have very tiny wires in them and without any visible damage, they can go bad. I have several different kinds of chargers for different locations where I mount and use my Ipad, and every once in a while, I have to switch the charging cable to get it to work. It has worked well since I replaced that one cable. I found them cheapest on Amazon.com. Apple wouldnt offer any suggestiond or ideas at all. They were about as helpful as an ashtray on a motorcycle. Which was really stupid since the solution was to simply change the cable. If that doesnt work, I would then replace the actual charger part that plugs into the wall too. (again, the cheapest ones are found on Amazon.com and they work fine) Be carefull which one of those you get, not all of them are rated with the correct voltage. Theres no risk of hurting the Ipad if you use the wrong one it will just start charging it, or not. Be patient in letting it try.
Also, if it ever locks up on you, hold in BOTH the button on the front and the one on the side and it will force it to shut down, then you can reboot it and it should be fine.
I won mine at a raffle, and Apple acually told me that since the company that raffled it off had it sitting on a shelf for a while, my warranty was void before I opened the box.
Be careful what you buy from Apple,...."Resistance Is Futile!"
Hope rthis helps.
John.
