I have tried all that you have said from multiple power sources but it is totally dead.
I have tried a different cable and have used the cable on another device and it is fine.
I have had the Ipad some time and it is not had a battery change.
Guess I have to take it to the nearest Apple Store. I do not think I could fix it myself>
I feel that is the only option. I will have to travel 50miles to the store but I do not know of any technicians near me who could do the job.
Many thanks Freddy
