Last edited by Quarter on 2019/12/9 09:37 As described above, the webcam image has grey lines and occasional green flickers. This only occurs when AC power is plugged in, everything works perfectly when using battery. I have removed and re-installed drivers with no success. This is a brand new laptop that I removed from the box yesterday. I see that there are two other questions with the same issue, but no answer has been provided. Is this a hardware issue and do I need to return my laptop or is there a software fix?

Updating the bios doesn't work.

Hello arneparne, May I have your model name as well? And can you provide more description about the scenario? (Like only under AC mode, only when video calling, skype testing is fine...) Thank you.

This is a replacement of my other UX431FL-AN012T from this thread: https://www.asus.com/zentalk/thread-295697-1-1.html . It has the same problem. When the power is plugged in, lines sometimes appear on the webcam feed. It happens always, in any app. Not only when calling. This is quite disappointing.

I've exactly the same issue on the Zenbook 15.
