My camera is not found by my PC, though it's available in device manager.

My camera is not discovered by my PC, though it's clearly available in device manager.  I cannot roll back the driver or update it, as my PC always says I have the correct driver.  I've updated the BIOS and tried hardware fixes to no avail.  My PC does not have a camera "kill" switch, but it does have an icon of a camera along the function row, and I have ensured that it's not in the off position.

One other thing: I've tried to delte the camera in device manager so that the PC can detect that it's missing and reinstall it.  That doesn't work either.

Finally, when I try to enable Windows Hello sign-in, the camera is not functioning.  I just get a dark screen.

Any help?

Your laptop has a True Vision 5mp camera with a privacy door covering the lens.  Make sure it is open.

Try this HP universal webcam driver dated 2024

If it does not work then try a different driver as follows

• Click Browse the computer to select a specific USB Video Device driver.

  Double-click Imaging Devices to expand the list of webcam drivers, right-click the webcam driver, and then select Properties.  It may not be under imaging device

  

   

  Make a note of the existing name of the webcam driver (Example: HP Webcam), as it might change after the update.

• On the Webcam Properties window, select Update Driver....

• Select "Browse my computer for drivers"

• Click Let me pick from a list of device drivers on my computer.

• Remove the selection from Show compatible hardware.

• Select Microsoft in the Manufacturer field, and select USB Video Device in the Model field.

• Click Next to install the webcam driver.

• Allow the installation of the USB Video Device, and then click Close.

• After the device has been updated to USB Video Device in Device

You may have to try more than one driver. Possibly an older driver will work.

If the above does not work then please provide the VEN and PID numbers that identify the camera device.   For example the IR camera ID is 0408 and 545E 

The actual camera is also needed, not just the IR

Thanks for your exhaustive suggestions.  I’m out of my home until Monday but I’ll give it a go then.
