So I was accidentally carrying my MBP and my wallet (which has a magnet in it to clip money) together with my wallet being under the MBP, and all of the sudden there was a clicking noise that lasted for like 3 seconds form the left side of the laptop. My MBP was open with Chrome running and nothing on the screen changed but now I am worried that I screwed something up internally. There are no signs that I screwed something up but I am just scared because of the noise. Any thoughts? Thanks!
