Do not yank the upper case off quickly. The case is attached to the logic board via a ribbon cable.

Lift up at the rear of the case and work your fingers along the sides, freeing the case as you go. Once you have freed the sides, you may need to rock the case up and down to free the front of the upper case. This stage can be quite tricky. Over the DVD reader are 4 tabs set back which pull out vertically.

Note that the two small tongues on the left hand front of the upper case may bend while you remove the upper case. When re-installing, you may need to bend them back to fit in the grooves in the lower case.

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

Remove the upper case.

Disconnect the two antenna cables attached to the Airport Extreme card.

Deroute the Airport antenna cables from their channel in the left speaker.

Disconnect the iSight, inverter, and left fan cables from the logic board.

Disconnect the display data cable from the logic board.

Remove the silver T6 Torx screw securing the ground loop on the display data cable to the casing.

• Two 9.5 mm silver T6 Torx screws with threads on only part of the shaft on the inside of the display hinges.
• One 9.5 mm silver T6 Torx screw with threads on the entire shaft on the outside of the left hinge.
