This is very overdue, but better late than never.
Both resin and DevCon did not work for very long (<20 uses over a couple weeks). I am not 100% sure I received real DevCon plastic weld since I ordered online, but what I did try did not work long.
For every screw hole that ripped off, I ended up drilling holes with a 3/32 drill bit through the laptop lid, and using M2.5 screws and nuts. It’s ugly, and I have to be careful not to scratch anything because of the hard bits of metal on the laptop lid, but the laptop is usable.
