So, my laptop's a bit old. Maybe 6-7 years old. This

if that means anything. Anyways, the left hinge has been loose for a while now and it finally outright snapped, disconnecting the screen from the laptop itself.

Because I'm rather attached by this point, I looked up the manual and disassembled it.

I found the problem, a little piece that snapped off.

More specifically, this

is no longer connected to this.

I have no idea why. It could have been glued on, something with magnets, or maybe it was held together with magic. All I know is the opposite part

is still perfectly attached and seems pretty firm.

I'd be happy to know the part names because I'm at a complete loss here. Any help would be appreciated.
