Installing the System Board
Steps
1. Hold the system board at the center. Avoid holding the system board by the "neck" area to avoid damaging it.
2. Replace the M2x4 (4) screws that secure the system board to the palm-rest assembly.
3. Angle the system board onto the palm-rest assembly with the SD-card slot side. Angling it this way while mounting the
system board gives sufficient clearance as the audio daughter-board is beneath the other side of the system board.
