if you'de still want to disable it you should have a driver for the lenovo power management you should be able to disable that. Should have thought of that first. In device manager.
I installed the program, when disabled, did the rest, bet the poping didn't wanished
Sorry it never fixed the popping, like a lot of things it's trial and still error. Curious how it stops when you tilt the laptop does this happen when you're on mains battery or both try with main not battery attached too? Let me know
Here's post you may wish to read if not already done.
