RE: Misplaced Screws in the DVI port, I was upgrading an early 2008 MacBook Pro with an SSD to get some more life out it, and sure enough, misplaced one of these small screws into the DVI port upon reassembly. Screwdrivers, shaking, gravity... nothing worked. UNTIL I went to my dad's house and his super-comprehensive workbench, where he found a small, high-pull magnet and the little bugger flew right out. Refrigerator magnets won't cut it, you will need a more powerful magnet, such as these: http://www.kjmagnetics.com/products.asp?...
Hope this helps someone... it was an easy solution to a frustrating problem
