Removing motherboard from bottom assembly. I show a picture of the top palm assembly for precaution again.

Disconnect the two ribbon cables found on opposite corners of the motherboard.

The cable on the bottom left should have two pressure pins, if not just pull the cable out.

The cable on the top right will have two pressure pins for locking, release them and pull the cable out using the hard film.

Remove 8 screws from the motherboard using the #0 Philips Screwdriver.

4 black screws are found along the edges of the motherboard.

2 Metalic screws are found underneath the ribbon cable on the bottom left. Remove them. The last 2 screws are on the hard drive cage on the bottom right.

Enjoy the sight. You are done! There are a few other parts but those should be easy to remove from here.
