I am removing the two Philips head screws of the laptop which hold the keyboard of it in place. I was easily able to remove the first one, but the second one refused to come even with the correct screwdriver (the laptop was left in storage for nearly ten years). I applied too much force and now the screw is completely stripped. I tried using a rubber band for grip but that didn't work. What will I do now? I don't have any screw extractor or anything like that. Some screws on the back of it are also too tight and their surface has become brittle and I'm afraid I may strip those screws again. What will I do now??
