[desireek]

Hi.

I have new macbook pro 15 retina mid 2014 and i notice that when i lift it today and removed my hands under the macbook it came a kind of cracknoice/nock noice, only one sound every time my hand slides over the aluminum cover under the macbook, just like the aluminium plate under moves or something?

Anyone that have notice this before?
It is a nock sound when it happens.
Thanks for reply.

I think there are springs on the backside, that is probably what is causing the noise when pressure is applied. Mine does the same

I've got the same. It's completely normal.

Under the bottom plate some pins are located, which keep off the bottom plate from the logic board.

If bottom plate is pressed, it touches the pins, which makes the sound.



Make sure you put the MacBook Pro on a flat surface.
