usb-c dock just stopped working

[Kay_Wise]

My docking station just stopped working. It will power the computer but none of the ports operate. I saw online others have had the same problem, but I can’t find a solution. Yesterday, I unplugged the station so I could plug the computer into a new router. That worked fine, but when I plugged it back in on my desk, now I can’t use my second screen or mouse.  Naturally I’ve tried turning everything off – completely off- and back on again.  The laptop and dock are both just a few months old. Laptop is Elitebook 1012 X2, and the dock is usb-c, product ID T3V74AA running Windows 10 64bit.

first thing to do is make sure you do updates 

I recommend the use of HP SDM ( Softpaq Download manager - www.hp.com/go/sdm ) to update the system. When it runs and downloads the latest catalog,

   * select 'check for updates' tab - if not the default when you run SDM
   * install auto-checkmarked drivers, NOT the BIOS, at this point
           it may occasioanly suggest 2 versions of dirvers - select the latest one only
   * install any other (ONLY) drivers that show as Not Installed + Essential System Updates softpaq
   * select BIOS update (if needed) by itself and  Install
           DO NOT SHUTDOWN if the laptop beeps a few times during the BIOS update !!! Let it continue
   * Reboot

Thank you for helping.   I have done as you said down to the point of installing the BIOS.  It is not an auto-install, so was only downloaded.    Now I'm stumped.  Seems to be in C:\SWSETUP.   Once before I updated the BIOS on a computer so I'm aware the operation is delicate.
