Crackling noise inside a MacBook Pro when I shake it
Hello, my MacBook Pro sounds like there's something inside when I shake it, it sounds like a piece is moving, but the rare thing is that the sound only appears when it's turned on.
If I move my computer the the left, the thing goes to the left. If I move it to the right, it goes to the right. Up and down too.
It hasn't fallen.
It's a MacBook Pro 13" Late 2011.
Edit: Now it's happening without shaking the computer, just using it. I think it might be a problem with the fan. Any thoughts?
I found this video on the Internet, I think this is what it sounds like:
Is this a good question?
