Starting near the display and working around to the front of the computer, pry up on the upper case. A plastic opening tool or a medium hard guitar pick may help you to do this. The upper case is likely to stick at the connection above the optical drive. If this is the case, first free all other sides, then proceed to pull upward on the upper case from either side of the optical drive opening. /Guide/Installing-MacBook-Core-2-Duo-Left-Hinge-Mount/534/all#s2441 While holding up the upper case, pull up the black tab of the silver cable away from its connector. If there is no black tab, you can also use a spudger to gently pry the connector from its housing. This connector is tall, so be sure to pry straight up. If you happen to break your upper case cable when removing the upper case, we stock the cable individually and we have a guide that makes replacing it easy. /Guide/Installing-MacBook-Core-2-Duo-Left-Hinge-Mount/534/all#s2442 Remove the following 3 screws from the left hinge mount: One 6 mm smaller diameter Phillips from the right side.
