Steps
1. Align and place the I/O board with the slot on the palm-rest assembly.
2. Replace the four screws (M2x3) that secure the I/O board in place.
3. Connect the fingerprint reader FPC (for models shipped with a fingerprint reader), Darwin cable, fan cable, touchpad flexible
flat cable, and speakers cable to the I/O board.
4. Place the fingerprint reader bracket over the fingerprint reader FPC and replace the screw (M2x3) that secures the

The fingerprint reader bracket covers both the fingerprint reader connector and Darwin cable connector.
Models that are shipped without a fingerprint reader still have a fingerprint reader bracket to cover the Darwin cable
connection.
