Dell Latitude E7470 Black screen after undocking


We have a batch of these laptops and several of them keep black screening after undocking, the laptops then may take ten minutes to come back or may even require a reboot,  I have tried the following but to no avail.

updated the bios to E7x70_1.15.4  (07/06/2017)

updated the Graphics driver to Intel-USB-eXtensible-Host-Controller-Driver_4H5XG_WIN_5.0.3.42_A02 (10/07/2017)

Can someone please advise on the next possible action to be taken?

Hi London Techsupport Squad,

Please update the BIOS, chipset and then graphics drivers (in this sequence).

Also, what is the operating system installed and if it is Dell OEM Operating system?

Please click my DELL-username and send me a Private Message with the Dell Service Tag number and your email address.
