When I open my Mbp it goes smoothly but when I close it it pops EXTREMELY ugly. Strangely, if I open it more before closing it(in a fluid motion) it doesn’t click or pop. Please help.

Post some pics of the closed system along the edge (hinge side) as well as the the side. If that doesn't show the issue effectively take a video. Post them here for us to see 在已经存在的问题里加入图片

Thank you, I posted a video of the issue along with pictures that you said might help. If there is anymore i can do to isolate and fix the issue please let me know. Thank you!

Very odd in deed! At first I thought you had a bent lid or the hinges were bad.

I suspect the click you are hearing is from the speaker not the lid directly. Maybe a pinched wire?

Plug in a headphone into the output jack so the internal speaker is disabled. Did that solve it?

No, it is definitely not the speaker. you can feel the resistance and release after the snap/pop. Just to double check I did do as you said. I hear the pop coming from the right side of the laptop if that gives anyone any ideas.

Then my guess of a bad hinge is the case. I've just never heard such a defined sound like you recorded.

It seems a hinge problem to me, unless the Mac screen received lots of pressure when closed and the lid now touches the topcase when moving, but if this is the case you’d have clear signs on the painting on the back side. But still, a breaking hinge seems the most probable explanation. You can inspect what’s the situation by removing the screen, remove the black plastic clutch cover, mount back the screen with a couple of screws and see what happens when you close the lid with hinges now in sight. If ‘it’s a breaking hinge you can quite easily find replacements. You may get some help for the job from the following guide:
