Q: Why does my Mac Book Pro make a loud buzzing noise while it's on?

MacBook Pro (Retina, 15-inch, Mid 2015)

Processor: 2.5 GHz Intel Core i7

Memory: 16 GB 1600 MHz DDR3

Graphics: Intel Iris Pro 1536 MB

I've tried restarting and completely shutting down and restarting. My laptop continues to make a loud buzzing noise while it's on even when I don't have any programs running.

I've only had my laptop for 3 months and I have not loaded or downloaded any other software other than what came stock with the laptop.

What could be causing this?

How do I make it stop?

iMac, iOS 9.3.2

Try SMC and NVRAM resets:
