I have looked through some of the community posts about this, but am between categories for this issue. My lid has not come off completely yet, detaching partially from the rear right hinge. Many of these posts discuss what to do with a clean break of the adhesive, but the few discussing a partial detachment are right after receipt of their new unit. I don’t want to do damage to the unit by trying to detach it enough to clean and reglue sufficiently, but haven’t found any walkthroughs of how not to.
My unit has been in a pretty thermally stable environment - always air conditioned in Florida, so there aren’t the temperature swings as severe as many debating the source of this issue have discussed. It seems like there’s just a basic design vs. physics issue in terms of having a materials break on top of a tensioned hinge.
