I’m not sure how many of you out there do a lot of CPU swapping, but if you’re like me and do it every once in a while, you know the terror that strikes when the processor doesn’t seat right. “Did I get the wrong socket? Did something break off in transport? What could it be, oh god!” Or something like that. Well, nine times out of ten it’s just that one or more of the pins on the processor got messed up while you were taking it out of the packaging, or when you were positioning it. I fixed mine once with a pen, but this mechanical pencil method is way better, and almost certainly applies to other situations where exposed pins get all janky.
