PC: X1 Carbon 20HK
OS: Windows 10 v 1803
Graphics Driver: 184.108.40.206.6344
Issue: In Device Manager the 620 driver displays a code 43 error. This does not effect the running of the PC but stops the PC from been connected to an external Dock a Lenovo C-Dock (Type 40A9) as external docks require updated graphics driver and USB3 drivers.
- Using a downlevel driver 220.127.116.1115 - failed
- updateing to current driver 18.104.22.168.6344 - failed
- Ran full Lenovo System Update and updated EVERY driver \ firmware possible, including the C-Dock - Failed
- Found web forums that pointed to BIOS VM settings "interfering" so have disabled virtualisation in BIOS - Failed
This is the 3rd 20HK that has had this issue and both the others in the end for speed they where just rebuilt (SCCM Corp Image) we have 40+ 20HK's and this is the 3rd so no consistancy that we can see yet.
The PC's are fully MS Updated. There must be a update \ process to get this working as a rebuild is easy to say but pain in the arse even with a really good SCCM OSD.
Thanks in advance

One of the other engineers fixed this issue, putting this up to help other people.
Used DDU (https://www.guru3d.com/files-details/display-driver-uninstaller-download.html) to low level uninstall the driver and then load the Intel drivers for the UHD 620.
This fixed the issue :-)
