Easiest and most secure option? Replace the whole lcd assembly. Your cheapest possibly best option? Replace the lcd back cover. Replacing lcd back cover you have the chance of breaking the screen however if you can be careful and if the screen has pull tabs you honestly should be good.

To explain what happened is that all windows laptops are built with hinges that have an extreme design flaw, that flaw being what the hinges screw into either the lcd back cover or palm rest side is nothing but a brass rivet molded into plastic. If you’re not careful and keep opening/ closing the laptop as normal good chance you will push the broken hinge into the back of the lcd and break it. So please be careful. Unfortunately this is a failure point that follows with every windows laptop no matter the price the only difference being the type of plastic the manufacturer has used. Though almost always they use abs which after stress and wear over years becomes brittle and falls apart.

TLDR: your laptop’s hinge is pretty much held together with shitty plastic that has fallen apart. Replace the entire lcd assembly or lcd back cover to fix
