Installing the System Board

4. Connect the power-adapter port cable, speaker cable, keyboard-control board cable, touchpad cable, and touch-screen cable to the system board.
5. Connect the display cable to the system board.
6. Align the display-cable bracket with the screw hole on the system board and replace the screw (2).
