I have tried the following:

- Swapped out the battery inside the tablet
I can confirm that the tablet will only take 400mA of current which isn't enough. I have a second P7500 and that one works well and pulls 1.3A when charging.
Are you on stock ROM or custom ROM? You may need to restore either. If you have swapped the battery with one that is presumably good, then you may be stuck with a corrupt firmware. You may also try changing kernel.
