Add Note Edit Step 30  ¶ 

  • Before you can yank the upper case off, you must disconnect the trackpad connector, the blue and white power cable, and speaker cable as described in the next steps.

  • Lift the upper case from the right side and use a spudger or your finger to disconnect the trackpad connector hidden beneath the white plastic tab. Due to model variatons your trackpad connector may be different from the one pictured.

Add Note Edit Step 31  ¶ 

  • Carefully lift the upper case about half of an inch and move it so that you can access the power and speaker cables.

  • If the upper case is sticking, it may be necessary to free the tabs holding the upper case to the metal framework along the outer edge of the battery compartment.

Add Note Edit Step 32  ¶ 

  • The connectors at the ends of the cables are attached very firmly to the sockets on the logic board. Pulling directly on the cable will either separate the cable from its connector or the socket from the logic board.

  • Lift the upper case enough to disconnect the blue and white power cable from the logic board. Using your fingernails or a dental pick, carefully pry the connector from its socket. Make sure you're pulling only on the connector and not on the socket.

Add Note Edit Step 33  ¶ 

  • Lift the upper case off completely and disconnect the multicolored speaker cable from the logic board. As before, make sure you're pulling only on the connector and not on the socket.

  • Tip: the multi-coloured cable may be easier and less daunting to disconnect after removing the top heat shield. Prop the top case upright while removing the shield - the connector is then much more accessible.

    • Fourteen 3 mm Phillips.

    • One 5.5 mm Phillips in the upper left corner.
