Slide the cover towards the screen hinge to disengage the clips on the opposite edge.

Lift and remove the cover.

The cover should come away easily. If you feel resistance, use the flat end of a spudger to release any remaining clips.

During reassembly, slide the clips along the front edge of the cover (opposite the hinge) into their slots on the frame, then lay the cover down. Firmly press around the perimeter of the cover to engage all the clips.
