I have a lenovo g530 and the screen keeps flickering on occasion. Sometimes it is worse than others, and sometimes it doesn’t seem to do it at all. I was able to capture a video of it so you could see what is happening. I kinda wanted someone else’s opinion before I open it up and check the monitor cable on the board.
- Video Link (in case you missed it above)
Solution:
Like Michael commented: this looks like a cable/connection problem.
I have something similar on one of my laptops, where I get the lines you see in the video. In my case pressing on the GPU part of the motherboard stops the flickering, but it also depends on the angle of the screen.
This makes me assume it’s a cable problem, that’s not connecting properly.
I wish you luck with opening it up, but if it’s still got warranty, I’d sent it in… Even though you’ll have to miss your laptop for three months
