Disconnect the trackpad and keyboard ribbon cable from the logic board, removing tape as necessary.

Note: It is possible to replace the hard drive without disconnecting the keyboard from the chassis, but it will need to be held upright to keep it out of the way, while still allowing you both hands to work on the drive removal. Be careful when removing the keyboard-trackpad ribbon cable to ensure that the rear of the upper case is disengaged from the area near the hinge. It is easy to accidentally bend the screw receivers on either side of the keyboard.

• Remove the upper case.

Disconnect the two or three antenna cables attached to the Airport Extreme card. Depending on your model, one of the three cables may be unused and capped with a black shrink tube.

Apple was kind enough to include a label showing where each color antenna cable plugs in - just make sure to look at this when reconnecting the antenna cables.

• One 9.2 mm full thread T6 Torx screw securing the iSight cable ground loop to the fan.

Disconnect the inverter cable from the left I/O board by placing a spudger beneath the cable and lifting up.

Disconnect the display data cable from the logic board.

Remove the foam bumper from the top of the right hinge of the display.
