Rattling/Grinding rMBP 2012 15inch

[muffinman3679]

Strange grinding and rattling noise coming from retina macbook pro 15 inch bought in september 2012. Just noticed the sound today as it was stationary on my desk, pick it up to notice moving the laptop in upward/downward motions recreates the sound as if something large is moving around.

My main concern is. if the problem is unfixable and merits a replacement, will i receive the 2012 model (as i desire), or will i get the latest model that only has integrated graphics and fragile glass display...

any insight appreciated or if anyone else has had a similar grinding noise. Seems to get louder depending on the laptops heat.

Could it be a fan hitting/touching something? I believe a number of fans have been replaced in these.
A visit to the Apple store may be a good idea if the noise is readily reproducible.
I would imagine they would replace just the fan if that's the cause.

Just Command+A Command O all applications to test if it was the fans, no luck.

It just slowly builds up as the laptop heats up, tried maxing the fans on smc and didn't cause the grind :S.

I live in new zealand and we don't have apple stores here unfortunately.

Hmm, interesting. Not many moving parts in a rMBP

That is my thought too, either something has crept behind the keyboard if thats even possible, or something is loose, possibly battery shaking around. i'll contact apple support tomorrow, I'm just so glad i opted for the extra warranty, funny how problems pop up mere months after standard warranty expires, very suspicious ;P

I think the battery cells are well stuck down.
Maybe an internal screw dropped out or something.

Regarding your second question in post 1, if it comes to the point of the machine being replaced maybe you could ask specifically for a refurbed 2012 model. I suspect there'll be a few about.
