I've searched everywhere, and i can't find a thread or video about removing the whole top portion of the mbp off. all i have found was how to replace the screen, but not the actual top with the hinge etc. when i close my mbp, the top part isn't aligned properly. the right corner of the bottom half of the unibody shows, while the left corner has a portion of the top portion overlaying the botom portion. hopefully that makes sense. is it hard to remove the whole top? how do u do it? is it worth risking my warranty? thanks all!
