Do not yank the upper case off quickly. The case is attached to the logic board via a ribbon cable.

Remove the ten silver T6 Torx screws securing the display (five on each side-take note that the inside screws on both sides are longer with a thinner head).

Don't forget to replace the hinge end caps when reinstalling the display assembly. The end caps are side specific, so be sure that the posts are facing towards the lower case.
