That’s my personal PC, so I don’t care about looks, I mostly want a strong connection to the whole notebook’s bottom casing so I won’t break it by touching that part of it while taking it up by it.
I have superglue, hot glue, metal sheets, can purchase screws and such, am not limited of basic supplies, but I have no idea how a pro would go about it.
Deeper description: it’s occured to the bottom part of a notebook holding most hardware. The corner itself is empty so no hardware there. It broke off in one piece, but have itself two still intact details - one is a part of a flat surface that you put your hands on while working, the second is a bit rounded reaching the bottom.
I came to think I want to fix it with some sheet where it is flat, and then glue it to it’s curvy bottom.
Goop adhesive.
Very strong, remains flexible to tolerate loads. Easy to apply.
Best thing about Goop - if you don’t like how it works for a given problem, you can remove it! (It can be peeled off, though it’s adheres very strongly.
I’d slather a bunch on the broken piece (enough so some will ooze inside the laptop and outside too), then push it in place and quickly rub off any that oozed out. Don’t worry though, if you miss some on the outside, it can be rubbed off later after it cures - just don’t pull on it as that will pull it out of the joint. Rub across the break - this will remove the excess without pulling it out.
That’s where I’d start, and see how long the fix lasts. If it eventually did fail, then I’d use an epoxy like JB Weld/PC7. With JB Weld you want to have a solvent on hand to clean off any that oozes out onto the case (rubbing alcohol or Goo Gone, neither will dissolve the plastic).
I’ve sometimes used 2 adhesives like JB Weld and a couple spots of crazy glue. This would keep a piece in place with the crazy glue whole the JB Weld has time to cure.
I suspect you’d have success with one of these adhesives.
