This is years out of warranty, it’s a 7th gen i5 :)
The photo is of the top part of the laptop base, so where the keyboard is, but from underneath. The base below it was already broken, which is what put the extra strain on the top.
As you say, I should be able to put some epoxy on and hold it together, as none of this needs to be removed again. I’ve got a new base coming, so as long as the pictured piece doesn’t move, it should be fine :)
