If you search the forums you should be able to find how to do a factory reset. I think you have to hold the N button either during or after you do a hard reset.
That might fix the issue where it's not loading.
Of course, this will lose all your data (for apps, any content you might have sideloaded, etc.). You'll have to redownload books and apps.
I did the reset to factory and reregistered and it still goes black whenever it is disconnected from the charge cable, battery stats states 100% charge now.
Thanks for the reset suggestion but is still not working any other ideas?
