Hi,
I’m having a problem with my laptop camera. It seems that IR camera stays on, even though I don’t use it for anything. I can see it shining red even with the privacy cover on.
I’m not sure how to disable it. There is no BIOS setting to disable just this camera.
The problem is that both cameras are on the same bus, so when IR camera starts acting up regular camera doesn’t work either. But I need the normal camera to keep working. I am not sure what exactly the problem is, but I would like to block IR camera from engaging and see if that fixes my problem.
Here are some things to help out with debugging.
