When removing or installing tiny laptop screws: The Dell laptops that I've worked on had screws that took a Phillips # 1 bit. The only screws that differed were tiny screws as part of the optical drive, hard drive, and fan. There are tricks that can help to remove a screw with a stripped head, but many of them are difficult to do on tiny laptop screws. These include placing a piece of rubber or elastic between the driver and the screw, using a gritty paste (such as mixture of water and baking soda, cleaning powder or sand) between driver and screw, grabbing the screw with needle nosed pliers and turning it, etc. This article has some tips. A screw extractor can be a lifesaver, though it may be hard to find one fine enough to handle tiny laptop screws. Some types use a two-step process: one tool cuts a thread into the screw head, while the second tool grabs into that new thread to turn and extract the screw. The type I have is single-step, as the tip is very sharp, hardened steel that cuts into the screw to grip and turn it. I recently had to remove this screw that someone else had stripped: [IMAGE]   I used the smallest extractor from my old screw extractor set. I applied firm pressure and turned very slowly. It worked. I expected that my screw extractor might not work, since it is made for much larger screws than laptop screws. But, as it is very well made with fine, sharp edges and machined to a fine point, it was able to cut into the tiny screw head. [IMAGE] Where are you located? If you happen to be in Toronto, I could remove them for you.  
I have a Dell Inspiron laptop.  I am trying to remove a couple of the screws from the back of the laptop, which I have removed many times and now the screws are stripped.  I need to know how to remove a stripped screw?  I have tried the advice on Google which non of these worked so now after all these attempts the screws have now have a nearly round hole!
