The left hinge of my MacBook is suddenly very stiff

Hello everyone!

A couple of days ago, the left hinge of my MacBook Pro started to be very stiff. If I try to close my screen, it pops back open. I first thought that there was something stuck in the hinge, but I didn’t see anything. I tried wiggling the screen a bit, but it only made it worse. I am also a bit worried that if I open the case, the hinge will be broken and instead of being stiff, it will be very loose.

I tried searching the web, but I can only find MacBooks with loose hinges instead of (1) really stiff hinge.

Has anyone seen this problem before? I hope someone can help!

Yes, we have seen this a few times!

Get some WD40 spray it into the cap to concentrate the spray into a puddle (it doesn’t take much!). Use a Cotton Swab (Q-Tip) to dip it into the cap and then wipe the gap between the hinge.

Thank you very much for your help!

So I just need to remove the bottom plate and I can access the hinge?

Yes, let's first try the simple fix before we dig deeper. Don't soak it! It needs less than a drop.

I have exams for school this week (at home), so I'll try it next week. I don't want to do damage when I still need my computer.

I'll get back with my result!
