What can ring inside a macbook?

Question

macbook

Model: Macbook Pro Retina without CD.
Macbook is new, bought about 6 months ago. At the same time, I have already visited the service center 3 times, then the cooler me, then the usb port, then the charger. Today I discovered that when I turn the MacBook over, there is a ringing inside, the sound is as if the bolt is rolling, and the sound is heard only when I digest it away from myself, and then when I turn it over, the part seems to be rolling back. If I flip left or right, then there are no sounds. What could be the reason for this and should I contact the service center?

Answer 1

New, six months? Change under warranty! This item is to be returned immediately. It's not a $3 calculator you want to repair through a toaster.

Answer 2

- Doctor, my balls are ringing! Am I a Phenomenon?
- No, my friend, you are a fool!
In the service, which was last repaired, and urgently, until it went short.
Bolt forgotten inside. Repair under warranty is their cant.

Answer 3

I think you answered the question yourself) this is really a bolt, most likely, and since you personally don’t disassemble the poppy yourself, you can do it in the service center for free, since it’s their fault that they didn’t screw something up

Answer 4

The bolt was dropped, what else ...
Soon it will close something there and then goodbye to the motherboard.
