Sorry but this is just the way my mind works. Does anyone know what the mechanism/mechanics are behind how a laptop hinge maintains friction with so much use? I now have an Acer Ezel computer which incorporates two such hinges into the screen fold and I have just always wondered how in such a small hinge profile to they maintain friction over so many cycles? One would guess that in short order the hinge would become loose and flopy and the screen would flop open or closed but it never happens.

Just an inquisitive mind thing with nothing behind it.

I remember older laptops having a fairly large hinge area but the new ones, while the screens are much lighter, are just so small.
