Place the keyboard into the casing starting at the power button side, we need to get the power button back in its location 1st before we place the keyboard into its resting position.

Take care not to damage that grounding wire and its soldering point.

Once the keyboard is in position it is time to screw down all the 80 or so screws needed to get a nice tight fit ready for use. Do as many as possible as the more the better!
