Lenovo Yoga 720-15ikb (LA-E552P) - Burned IC, can not read marking
This Yoga 720-15IKB (board LA-E552P) has a burned PU501 IC. As there is no schematic or board view, I am guessing that it is some kind of step-down converter for some rail, maybe 3.3v? I can not read the markings to find a replacement....

Disable dGPU MSI-16J91
I have a MSI-16J91 rev 1.0 motherboard with defective nVIDIA GPU. I want to disable it and be able to use only iGPU. Do I remove choke 5, 6 and 8 to accomplish that? Choke 3 was not installed from factory.
