Place the palm-rest and keyboard assembly on a flat surface.
NOTE: The power-adapter port is secured in place by the left display hinge. There is no screw, tape, or adhesives securing the power-adapter port to the palm-rest. As a result, technicians should take note of whether the power-adapter port has fallen out of the system during subsequent removal procedures.
Slide the display assembly at an angle and place the display assembly on the palm-rest and keyboard assembly.
Gently press down on the display hinges to align the screw holes on the display hinges with the screw holes on the palm-rest and keyboard assembly.
Replace the four screws (M2.5x5) to secure the display hinges to the palm-rest and keyboard assembly.
Route the speaker cable through the routing guides on the palm-rest and keyboard assembly.
Route the WLAN antenna cables into the routing hooks, on the palm-rest and keyboard assembly, and under the speaker cable.
Connect the display cable and speaker cable to the respective connectors on the system board.
