Turn the computer over again and press down on the metal notch. This will push the keyboard out of its place.

Once you can get a firm grasp on the keyboard make small motions side to side and pull it out of place.

The top and right side of the keyboard should be out when you grab it, so to slide it out pull in the direction away from the lower left corner.

Make sure not to pull to hard as there is one last connection under the keyboard that could be severed.
