You are asking how do you re-attached the heatsink with that particular screw.. I had the same issues took for ages n ages.. then I got it..Then I was working on the DIMM .2 and realised there is a much easier way... But I can't really remember now.. Maybe it was to secure the M.2 Drive in place with some double sided sticky stuff.. heat spreader stuff and it keeps its position much easier...
