I bought a precision screwdriver set to replace the failing RAM on my thin lenovo laptop, which has super tiny screw on the ram slot, withing the first few turns of the screwdriver, I stripped that screw. Fucking thing would not budge, tried the rubber band trick, tried to even find somewhere I can borrow a dremel to cut a line on the head for a flat head, finally had to take it to the repair center at a Micro center and they somehow got it out. Never buying a thin laptop again, and will always check online for repair ability
