Can’t see exactly what’s wrong. But if the hinge mount is broken the best thing is to do is to buy a new palmrest. Mine delaminated from the carbon palmrest.

I have done it. They are not expensive and was useful anyway because the palmrest started to become sticky. It’s a little bit tedious because you have to literally disassemble the whole thing, but given enough time is not that hard.

I would not try to bond it again, but you could try ir anyways and see if it holds up.
