Longtime Thinkpad user/abuser here, planning on assembling my just-received kit over the holiday weekend.
A longlong time ago, I got into the habit of using purple loctite
on laptops/celphones as they were going back together, to reduce the general tendency of screw creep and creaking, and part of general belt-and-suspenders levels of caution. It hasn’t interfered with subsequent reassemblies, and that’s with phillips-head screws.
…I know I don’t, which is why once I noticed that IBM used to do this when they built the machine(Why the FRU manuals reccomend replacing all the screws on the reassembly. Their screwkit comes precoated with their locktite), I started doing it when I put it back together:
The purple stuff is /really/ gentle - It just mainly provides a little drag.
