Once all screws have been removed , place the laptop on a flat surface and insert a metal spudger in a gap between the top side coverings.

Once inserted, move the spudger around the base, lifting the top edge about quarter of an inch. Gently go around the edge repeating the action.

The sharp popping sound that the latches on the inside will produce is normal and does not signify anything being broken.

While some force will be required in this step, make sure not to over-apply pressure since extra force might break the plastic latches.
