Those are not rust, but Loctite



As for the screw, try to buy few kits of screwdrivers with different fitting, as you never know when you may encounter tight screws which have issue to be unscrewed with less than perfect screwdriver fitting. From experience, a philips with close to 45 degree angle tip generally have better grip on laptop screws. I heard bout a theory before that these laptop screws are actually using JIS standard instead of Philips, hence often you get imperfect fitting using Philips screwdrivers.


The easiest way to unscrew worn laptop screws are using a dremel to cut a "-" flathead mark then unscrew using flat-head screwdriver. Though if the screws are deeply embedded, then it's more problematic.
