Display hinge click when closing lid

My MacBook Pro 16” (CTO) that I bought in early December started clicking randomly in the left side of the display hinge when closing the lid and 100% silent on the right side.

To make it clear i’ll make a description of the issue:

  • Click sounds exactly like a metallic spring under tension, only clicks once and sometimes twice.
  • Occurs around 30 / 50 degrees angle, always around those two angles.
  • Only occurs when CLOSING the lid and when doing it “gently”.
  • Sometimes the lid is completely silent when closing and sometimes it clicks every time.
  • The clicking has in the last 2 days disappeared on the left side and now only occurs on the right side.
  • Display hinge feels 100% smooth and is not loose, feels similar to my 2015 15” in terms of how firm the hinge is.
  • The display lid aligns perfectly with the rest of the laptop, does not move or shift when clicking so I could physically feel the click.
  • Seems to occur more frequent when the laptop is in colder room temperatures or have been closed during the night.

My guess is that that the spring for the display hinge gets stuck or something around 30*/50* angle which results in a click when it moves, can it be due to insufficient lubrication of the hinge?

Is this a common issue with the 16” since I tested it on two display models in a store and they both made a similar noise.

Is there anyway of fixing it myself? I got AppleCare so if its annoying enough ill bring it in.

@antarti - My 16" MBP makes the exact same noise on the left hinge. I have never dropped or damaged my MBP. What did the Apple store say about it?

Same issue on the same notebook as well, it started like a month ago and I was just ignoring it at first, but it started annoying me badly. I plan to bring it to the Apple store next week, hope they‘ll repair it without an additional cost even tho I don’t have the AppleCare+[br]

Hi! @antarti have you resolved this issue? I have the exact same problem with my new macbook pro 13inch.

This is happening with my 2020 MBP, was there ever a solution or is it just a sound it makes just before closing the lid?

To soon to say if this is a common issue with the new 16” models. But what I can tell you its not a big issue with the 15” models. And the design is just a scaled up 15” display. I had one system which was dropped which had a problem similar to yours.

I would strongly recommend you buy the AppleCare+ contract if you haven’t already.

I would make the effort to visit the Apple Store after you’ve bought the AppleCare+ contract so you at least register the issue.

The newer butterfly keyboard systems and your 16" system have a sensitive area where a bang can cause damage along the black clutch cover between the fragile ribbon cables and the T-CON board.

Looking at the hinges we can see how it works

The pin might have broken free from within the lid casting so it’s not fully secured so as you tilt the lid the pin rotates when it shouldn’t. This would require a new display assembly.

Cheers for the reply!

I got the Applecare warranty when I ordered the computer so that's all good.

Did the 15" that you looked at have any visible damage or could it only be seen within the computer / heard? Is it the clutch or the pin that produces the "click/spring noise" when it rotates and do you have any idea on why it only occurs sometimes? For example, this morning it clicked once and since then it haven't made any noises even though I've tried to reproduce it.

My 16" doesn't have any visible damage and hasn't been dropped / damaged in any way.

Hopefully, if I go to Apple with this, the turnover for a new display assembly won't be to long :-).. (Got no idea how long it would take for them to fix it)

Cheers!

@antarti - the lid casting was cracked from a drop so the pin was rotating.

@danj Alright, don't know if this is helpful but managed to record the clicks since it now all of a sudden started doing it again when closing the lid.

Sample 1: Multiple faint clicks and then a louder click.

Sample 2: Just one louder click.

Is this similar to what you heard on the damaged laptop?

Sorry I don't remember what the sound sounded like.

@antarti Did you get your issue fixed? Any idea what was wrong?
