Insert the plastic pick card into the gap between the frame and the cover. Move smoothly around the perimeter without applying excessive force to avoid breaking the fragile plastic or damaging the antenna inserts.

Once the cover is removed, immediately disconnect the battery connector from the motherboard. This is a critical point that prevents short circuits during further work on the components.
