I've used the Gateway M275 repair manual to disassemble my laptop for a repair job and (while I'm in there) some cleaning. I have never done this before, and while I think I remember what screws go where, I'm worried about putting something back in the wrong place. (Specifically, I'm worried about putting in a screw that's too long and shorting out a board.)
The repair manuals I've found for the Gateway M275 don't seem to have screw charts or any diagrams that help place screws in the correct locations.
How can I make sure I'm putting in the correct screws that will both hold the part in place and not interfere with any other components?
