The object of a left hand drill bit, if used right and you are lucky, is to catch and then unscrew the screw.
I have worked on HP laptops, there is ZERO chance ANY "lefthand drill bit" is going to catch enough material with out doing collateral damage to said laptop..
We are talking a very TINY SCREW here, not a manifold bolt on a vehicle. That screw is also held in by blue thread locker making the chances of breaking off the harder drill bit pretty darn good.
That TINY little screw is countersunk into the plastic with nothing protruding above the plastic to grab so pliers, cutters can't get anywhere near gripping the head.
It has been a while since I worked on a HP laptop( and glad of it, they are a PITA) so I can't remember if the access panel slides off or if it pulls straight up.. If it pulls straight up, removing just the screw head by drilling the head off is the quickest, safest way.
Personally, OP should take it to a PC shop and pay to have them remove the screw before more collateral damage is done in the process, PC shop will have better screw drivers that don't strip screw heads, heck, they may even have to apply heat to the screw to loosen the thread locker.
