Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

Use a Phillips #0 screwdriver to remove the five 17.2 mm‑long screws securing the top edge and bottom corners of the back cover.

Use a Phillips #0 screwdriver to fully loosen the remaining captive screw at the center of the bottom edge. This should create a small gap between the back cover and chassis.

Don't try to remove this screw.
