Hello! I notice a buzzing sound at the top of the keyboard, roughly where the processor is. I sat in complete silence and the fans of my laptop barely rotated, so I could hear the buzzing that the denunciation was coming from near the R key. What is this buzzing? Are those cpu inductors or not?

    Yes. Very likely small inductive coils that operate at different frequencies on the mainboard. Otherwise known a coil whine. A "buzz" sound suggests a coil frequency in the 100-200Hz range. Probably GPU. Volume level should change depending on the GPU load. Normal.
