I am sorry to hear that you are having this issue.
I am sorry about this,unfortunately this sounds like it might be a hardware issue. We will need to rule out the possibility of a firmware issue by resetting the software, using a force reset method while USB charging. If this fails then there is an hardware issue on the device that software troubleshooting can't resolve. Try these steps please>Connect the usb charger to the nook and a wall outlet charger. Then Slide or press and hold the power switch for 40 second, then release. Wait 15 minutes then power on and check. If that fails and you are sure that the charger is working properly then that means the nook has a hardware failure.Usually the cost to repair is too much and the best option is to purchase a new or refurbished nook which is a good value,
You can read the books from another device or computer while you are getting the nook replaced with the Kindle app which is available for most major smartphones, tablets and computers. That means with your free nook reading apps, you can buy a nook book once, and read it on any device with the nook app installed.
