Remove the 22mm power cable ground screw with a T15 Torx screwdriver.

You should now be able to swing the Bottom Housing out enough to disconnect the Hard Drive Data Cable. Again, only pull on the blue plastic connector, not the ribbon cable.

There is no need to remove the remaining connectors from the logic board.

Prop the Bottom Housing up so that it does not put strain on the remaining cables and connectors. Let it rest vertically, perpendicular to the Upper Housing.
