You need to buy the front cover with the cheap black plastic pieces that run from top to bottom for the hinges to screw into. It is a manufacturing defect as far as I could see. I bought a used cover with a capacitive touch screen already attached. You never know if the touch screen and related board are ok. I paid $50 on Ebay and it worked well. It was not too difficult to replace but the real problem is it is happening again on my left hinge. Dell need to recall the covers with the cheap black plastic strips and solder or weld nuts on the covers for hinges to screw into.
