Continuing the discussion from Hinge Replacement update!:
A little while after installing the new 4kg hinges I noticed that, with the lid closed, the back of the bezel/laptop was bulging a little on the right side when the lid is closed.
The TL;DR as far as I can see is that the routing specified in the relevant guide step is not possible, at least with my laptop. The cable is just a little too short, and the angle/location of its connection to the ribbon cable part of the run just too awkward, for an over-the-hinge routing as the guide specifies.
Under the hinge “works” however
The only way the webcam cable can be routed is under the hinge. That’s presumably the reason for the bulge: the cable is pressed between the hinge and the bezel, because it’s not supposed to be there. Cosmetics aside, those compression/decompression cycles on the cable can’t be a good thing.
I’m not sure how the cable was routed with the original hinges - I didn’t take “before” pictures.
I’ve opened a ticket wtih FW support but figured I’d ask the hive mind for any insights.
