File:Xps9550 cpu block screw broken 1 top.png

Summary
Top view of the damage caused to a Dell XPS 9550 motherboard when a heatsink screw pulled out of it. The original damage could have been caused by a drop (the laptop suffered multiple 4' drops onto tile) or, less likely, old age (6+ years).

Remove the original screw and replace with a small nylon nut and screw (M2 worked for me with a very small amount of blue threadlocker).
