Remove the following screws securing the camera data cable and right speaker to the upper case:
One 9.9 mm partially threaded Phillips screw
One 9.6 mm threaded Phillips screw
One 4 mm Phillips screw
Slide the camera cable bracket out from under the subwoofer and remove it from the computer.
The iSight cable has an eyelet through which passes the left-most screw in these pictures.
Grab the upper case with your right hand and rotate it slightly toward the top of the display so the upper display bracket clears the edge of the upper case.
Rotate the display slightly away from the upper case.
Lift the display away from the upper case, minding any brackets or cables that may get caught.
Carefully pull the camera cable connector toward the right side of the display and out of its socket on the AirPort card.
When reattaching the AirPort Cable, make sure that the U-shaped notches on one side of the cable end are not visible (facing the card). If the cable is installed incorrectly, it will cause logic board damage.
