It's stuck you should take it to where you have a warranty so they can fix the button that's stuck

1. Turnn completly off the tablet.
2. With the tablet turned off, holding the return button while turning on the tablet-pressing power button. Keep holding the return button until you see the Hard Factory reset screen.
3. Confirm the hard reset procedure. Once done, simply wait until process has finished-the tablet will restart. This process can take up to 30 minutes, so it's very important that the battery of the tablet is completly charged before attempting the hard reset. If you can connect it to the charger while resetting, even better.

only solution is to go for factory reset or firmware upgrade

From your description, the power connector could be intermittent but if so the tablet will have to be disassembled to make repairs.
