Cause
The camera may be disabled after a BIOS recovery when Latitude 7420, 7320, and 7520 computers are running BIOS 1.1.2 or an earlier version. Latitude 5420 computers are running BIOS 1.1.1, or an earlier version are also affected.
Resolution
Reviewing the BIOS camera setting reveals that the BIOS recovery process disabled the camera.
Dell released BIOS updates to prevent this from occurring. Version 1.2.3 is available for Latitude 7230, 7420, and 7520 computers. BIOS version 1.3.12 is available for Latitude 5420 computers.
If the BIOS camera setting has been disabled already, the setting may instead be enabled.
To enable the BIOS camera setting:
From the affected computer, open the BIOS.
Note: For more information about how to access the BIOS, reference Access UEFI (BIOS) System Setup from Windows on your Dell Computer.
