I have contacted Lenovo customer care service 12-15 times, but they do not resolve my issue even, I even want to talk with a supervisor, but they do not want me to talk with the supervisor. Every time I call them, they do not instruct me. What to do with my problems, I have the experience to use high-end gaming pc almost 14 years, but they think I am an idiot.

My problem is some portion of the display is not workable, even I change windows 10 to 11, but the same problem. My laptop does not start sometimes.
