rMBP screen gaskets seems to stick to aluminum ...

Hello all!
Me and a couple family members picked up some rMBP's for the holidays and I have noticed that if I leave my MacBook's lid closed for a while, when I come to open it I hear sound that seems as if the rubber piece around the screen (the gasket I believe is what it's called) was sticking and is quite noticable. The other MacBook's are practically silent when opening the lid no matter how long the lid is closed. I went to my local apple store and they told me that I am experiencing "magnet noise" because my macbook has "extra strong magnets"... I'm not quite convinced as I only hear the sticking sound when the lid has been closed for a while (probably 15 or more minutes).

Has anyone else experienced this? Is this normal? Or am I just being OCD right now?

Thanks a bunch in advance!!!

No, I didnt imply anything about the use of the paper, youre fine.

Yes, I knew it had to be new, only a newborn Macbook can make that noise.   Those hinges are cast, not machined, theyll wear quickly (not wear out, but IN) and the sound will rub out to normal.

OCD with expensive new equipment is normanl for anyone, thats no worry and OK for anyone really.

Peace

How hot is the case when you close the lid?

If you shut the systemm down and let it cool and then close the lid do you hear that sound after an extended period of time with the lid closed?

Are you sure it's not the hinge that is making the noise?

I typically close the case when it is a little warm to the touch but not hot. The aluminum between the top of the keyboard and the screen is probably about the temperature of a healthy persons forehead when I usually close it.

I decided to let my system cool down for about an hour and it didn't change the noise...

And I am actually not 100% certain that it isn't the hinge. But I'm attaching a video of me opening the lid twice... The first time I open the lid you'll be able to hear the noise in question. I then open the lid shortly after to demonstrate that it isn't there unless the computer stays closed for an extended period of time.

I would suspect the hinge (as LowLuster states above) more than the gasket. I have a 13" MacBook Pro late 2011 and I believe the materials used in the gasket and aluminum housing are the same as your model. I don't see how the gasket can stick to the aluminun as the aluminum has a flat/non-glossy finish.

Try to isolate exactly where the noise is actually coming from. One thing to try is to lay a sheet of printer paper along the front and side edges of the case keeping the paper one sheet thick (don't overlap). Try the same noise test. If you still get it with the paper in place (acting as a non-stick buffer), I'd say it's the hinge.

I get periodic hinge noise as well and what helped somewhat in my case was something I read here about running dental floss between the screen and where the hinge goes into the aluminum, just above the left-edge of the F1 key and the right-edge of the F12 key (at least on my 13" MBP). Do a Google search for "macbook hinge floss" and you'll get plenty of results describing the problem along with the flossing.

I'll give the paper test a shot to try to isolate the problem (wish I woulda thought of that before! XD)

I did a search on the floss trick that you mentioned, my only concern is whether or not this would void my warranty? Also, is it possible to get MacBook hinge lubricated by an Apple Genius instead?

Thanks a ton for the post by the way! It's immensely helpful!

Its a friction hinge, there are no springs in same,

and you certainly would not want it lubricated like a spring on your car hood hinges.

dont attempt to do that, of course

What do you mean by "there are no springs in same,..."? I suspect autocorrect kicked in and messed up the post when you were typing it?

And yeah, I would suspect that I wouldn't want lubricate a MacBook hinge as I would a door, or chair, think bad things would happen XD

meaning there are NO springs in those hinges.

theyre friction hinges, compression hinges

A friction hinge is also commonly known as a:
Constant Torque Hinge, Position Hinge, Clutch, Torque Hinge, or Detent Hinge.

Common Applications include:
Laptop computers; lids, doors and enclosures; positioning device for controls, monitors, arms, seat rests

(Air and Pro hinges diff but same type)

I doubt the warranty will be voided. The floss simply leaves a thin film of harmless wax which can help quiet the hinge noise which can also be caused by the black plastic hinge cover snapping or creaking against the aluminum body. The noise is NOT necessarily coming from the hinge itself (internally). One additional solution I've found is to periodically open/close the lid to it's full extent (open/close fully) back and forth a few times which helps to quiet the noise/creak somewhat for a short time. The creak also tends to happen in the same spot that the lid is opened to since we usually tend open the lid to the approximate same position (at least I do) every time we use it.

One thing I would NOT do is to use some type of liquid lubricant which can actually make things worse since liquid lubricants can attract and hold on to dust/dirt/lint/etc.

I tried the paper technique as suggested by SergZak, the noise seemed to very different with the paper in vs without...  Even when I left it closed with the paper in overnight.

I have taken a video of me opening the computer after the paper was left in overnight (though I probably should've lifted from under the paper rather than over) but I further suspect the gasket simply because of the sound difference.

Here is a video with the paper buffer, computer was left closed overnight to ensure no false positive/negatives for leaving it long enough: https://youtu.be/F0IRfoitIZ4

Here is the video without the paper buffer: https://youtu.be/PpDeUBCCFFY

There was still a slight sound but definately a little quieter with the paper.

What do you all think???

seen both videos many times, Mmhmm

Dont think anything, I know however that thats a rough detent transition on the friction hinges on your monitor as connected on the chassis.

it was a hair quiter with the paper because the hinge was a hair less closed.

I KNOW THIS is a new Pro, right? It has to be, because ONLY a new one can make that noise,   and ONLY for a while.

This will wear in quickly, its a slightly rough rollover from the closing axle on the hinge that will wear smooth quickly.

Okay sounds what I'm experiencing.

Kinda feel stupid for posting this discussion since it seems that it's mostly my OCD kicking in I guess.

Btw, you aren't implying that I harmed the computer using the paper trick, right?

Anyways thanks a ton for the information! You helped me a ton!

And yes this is a relatively new pro. About a month old. So you're right there!

No, I didnt imply anything about the use of the paper, youre fine.

I know this question is quite old but I had exactly the same issue. It is not the hinge and you were completely right that the rubber-band that surrounds the screen gets sticky. It is not hard to find out if you have the same problem. Cut a sheet of paper into strips so that they can be fit between the rubber-band and the aluminium case when you close your MB. Once this is done, leave the laptop closed as long as it would usually take to become sticky. When you open it now, the screen will open easily and at most, the paper sticks to the rubber band.

Getting rid of this issue, however, is up to you. What I did is to use rubber care which is usually a silicon-based fluid that is also used for the rubber seals of car doors for exactly the same reason to make them unsticky and keep them in good shape. I applied the spray on a Q-tip and carefully wiped rubber-band paying attention to leave it off the display (a pain to clean the display afterwards). It took quite a while with several iterations of using the cleaner and wiping it off again. I closed the MB for a day or two and it opened with ease again.

Please don't use any oil-based stuff that's not made for rubber/plastic. It will harm the material.
