Intergrated Web Cam Showing A Black Screen

[DTS73]

Hi All

I have a member of staff who has a HP Elitebook 840 G6 laptop which is having issues with the web cam.

He said that the web cam has stopped working.  He said when he tries it within Microsoft Team all he gets is a black screen.

I connected remotely to his laptop this morning and logged into Skype on his laptop.  Skype sees that a web cam is present but when you test the web cam you get a black screen.

In device manager it's showing two drivers listed under under Camera....HP HD Camera and HP IR Camera.  I've deleted both and rebooted the laptop and they are both re-installed automatically on login but i still get the same issue.

I've downloaded the latest web cam driver from HP and installed this too but it made no difference.

He has Windows 10 64 bit installed Version 1903.

Does anyone have any ideas on why this is happening?

Thanks

I've managed to resolve this issue by looking more into the problem.

I was trying to replicate the issue on the built in web cam for my laptop.  I had my laptop set up to an external screen and i had Skype open.  I realized when i closed the laptop lid the web cam window went black  I then remembered that some HP laptops ship with a slidable piece of plastic that slides across the web cam lens to prevent it from showing anything (see picture below).

I e-mailed the  member of staff and enclosed the picture below.  I explained that the web cam may be covered by the plastic cover and that he may need to slide it across to uncover the web cam lens.   The staff member just e-mailed me back to say the cover was over his web cam lens, he's moved it and now the web cam is working fine.
