How to solve Screen Flicker and Buzzing Noise on QHD 4k HD x620 High Definition Laptop

For me, the flicker is very debilitating making the laptop unusable. I have owned laptops for 30 years, and none of them bricked less than 2 years from purchase. I really like the 4k screen, so I just hope Intel can get their act together, become honest with their customers, and at least tell us how to permanently fix this issue.
