I have not used my webcam on the above-referenced laptop for quite some time. I went to use it on zoom (quarantine fun etc), and neither zoom nor skype will recognize that there is an integrated Webcam. After further investigation, the Camera app comes up with "0XA00F4244"NoCamerasAreAttached".
I have searched as much as I can - the webcam is enabled in BIOS; I reinstalled Windows; I have completed all updates in the updater, and nothing will work. The integrated webcam does not appear anywhere in device manager. I am, unfortunately at a loss.
