I currently have a HP Pavilion DV4000 laptop. The LCD screen is cracked and the left hinge has started to break. I purchased a new screen and top bracket with hinges on E-Bay. They arrived today. My question is can I replace this myself or should I just pay someone to do it. I tinkered with it a bit earlier and can't seem to remove the bottom cover(battery side) to access the bolts on the hinges and the wiring. I appreciate any advice. Thanks
