Caution

This procedure requires System Configuration. After you've completed all removal and reassembly steps, learn how to initiate the System Configuration process.

Removal

  1. Use the blue torque driver and 3IP bit to remove the two 3IP screws (923-10367) from the audio board connector cowling.

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

  3. Use the black stick to 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 (1). Then move the end of flex cable aside to access the 1IP screw in the lid angle sensor (2).

  5. Use the blue torque driver and 1IP bit to remove one 1IP screw (923-10476) from the lid angle sensor.

  6. Remove the lid angle sensor from the top case.

Reassembly

  1. Position the clip on the lid angle sensor flex cable so the slot and screw hole on the clip are aligned with the pin and screw hole in the top case.

  2. Use the blue torque driver and 1IP bit to reinstall the 1IP screw (923-10476) into the lid angle sensor.

  3. Press the end of the lid angle sensor flex cable to the connector (1).

  4. Use the flat end of the black stick to adhere the lid angle sensor flex cable to the audio board (2).

    • Important: If you’re installing a replacement lid angle sensor flex cable, peel the adhesive backing off first.

  5. Position the audio board connector cowling over the end of the lid angle sensor flex cable.

  6. Use the blue torque driver and 3IP bit to reinstall the two 3IP screws (923-10367) into the audio board connector cowling.

Caution

  • After you’ve completed all removal and reassembly steps, learn how to initiate the System Configuration process.

  • If you replaced the lid angle sensor, close the display for 20 seconds when prompted during the System Configuration process. If the display isn’t fully closed during the process, you'll need to install another new lid angle sensor. The computer will play a startup sound (chime) when the process is complete.
