Error 43 on intel HD graphics card Elitebook 850 G1 Windows 10

[alecz]

Hi.

We are currently having problems after upgrading 3 laptops to Windows 10 Enterprise (clean install).

All the 3 models are Elitebook 850 G1 with Intel and AMD graphics cards, notebook has modelnr: H5G42EA#ABN.

When the laptop booted from a HP 2013 ultraslim docking the Intel graphics card is reporting error 43, which means that when the user moves the laptop out of the docking station the monitor on the laptop is blank.

I noticed today if I boot the laptop out of the docking there is no error with the graphics card (no error 43).

I have tried uninstalling both graphic cards, installing the newest drivers from HP, from intel and AMD, tried older drivers from HP but no matter what we try it still boots with error 43 in the docking.

Any suggestions for this error?

I also have this exact same problem.

I have contacted HP support regarding the issue but we haven't found a permanent solution to it yet.

A workaround is to turn off "Hybrid graphic enhanced display feature" in BIOS.

Press F10 on startup->Advanced->Device Configuration->Untick "Hybrid Graphics Enhanced Display Feature".

This will disable the AMD Graphic Card but undocking/docking will work perfectly again.

Will update when I get a permanent solution from HP.
