They make screw extractor bits with thread that winds the opposite way from the screw itself so that the bit drills into the screw while turning counterclockwise, but I don’t think that’s worth bothering with here (and I’ve never seen an extractor small enough). Just drill the head off with a normal drill bit. The body will stay stuck in the hole, but you’ll be able to take the cover off and laptops are usually held together by so many screws that a missing one won’t cause problems.
