problem rj45 dock thunderbolt g2

[delescja]

hi, 

I have a Zbook 17 G5

I have a problem with my docking thunderbolt G2 230w.

I have disconnections with docking

• screen
• audio : sound disappears at launch of the kvideo for 3 seconds. After it's ok 
• lan : lose connection

I tested 3 docking. I have the same problem

I tested an other PC ans it's the same

Do you have an idea ?

thks

if you have updated the ZBook BIOS, you may have a problem with the TB dock's usb-c/barrel cable... in the earlier production life there was a problem with the cable connectors that could disconnect if moved slightly... i would open a case with HP support and ask for a dock cable replacement... they are easy to replace from the bottom of the dock

thks for your help.

But the cable is attached with the docking. I have Station d’accueil HP Thunderbolt 230 W G2.

the usb-c combo cable is attached to the thunderbolt dock, but can be replaced by removing the bottom unscrewing a simple screw... once that is done, you will see the same connection usb-c plus barrel connector connected under the dock...
