Removal

Note: If you’ve already completed the removal steps, skip to reassembly.

  1. Use the blue torque driver and 3IP bit to remove the two 3IP screws (923-12557) from the audio board connector cowling.

  2. Remove the audio board connector cowling and save it for reassembly.

  3. Lift the end of the lid angle sensor flex cable off the connector.

  4. Loosen the adhesive and peel the lid angle sensor flex cable from the audio board. Note: Use the black stick as needed to disengage the adhesive between the lid angle sensor flex cable and the top case.
