Buzzing noise in Lenovo ThinkPad P51

by Tomasz Jarosik

This happens e.g. when you scroll in the Chrome browser (or usually very often if you just move the mouse). It’s certainly related to the processor in some way; there’s a direct, noticeable correlation between the loudness/frequency/intermittency of the noise and CPU activity. It’s slightly better when you disconnect AC power, but still noticeable and, if you work long hours, annoying. When compared to MacBook Pro it (which is silen), was very noisy.

I found solution for myself, which is to disable CPU power management. My Lenovo P51 works silently now. There is a better description here:

Does that eliminate the whining also when GPU is under heavy load? Could you please check?
Thanks a lot.

Hi Piotr, Under heavy GPU load (like playing a game) built-in fan is quite loud, but I don’t hear any other strange noises.
