Removal
Note: If you’ve already completed the removal steps, skip to reassembly.
Use a torque driver and crosshead bit to remove six crosshead screws from the USB-C connector. Then complete the entire step before continuing to the next step.
Note: Four of the screws are located on the vertical edges of the enclosure.
Use the long crosshead bit to remove two screws on the bottom vertical edges of the enclosure. Ensure that the torque driver and bit are as parallel to the enclosure as possible to avoid stripping the screws.
Use a torque driver and the super screw bit to remove one super screw from the USB-C connector.
Lift the ends of the two stacked USB-C connector flex cables off the connectors.
Gently separate the USB-C connector from the enclosure.
Gently separate the microphone (attached to the USB-C connector) from the sidewall of the enclosure.
Break the adhesive bond between the USB-C connector and the enclosure. Then remove the USB-C connector from the enclosure.
Caution: Don’t pull on the flex cables while peeling the USB-C connector from the enclosure.
