Failing Thunderbolt G2 dock after BIOS update HP ZBook Studio G5

[Max1995]

Hello HP,

This morning I installed the latest BIOS update version 01.01.05 Rev.A. The installation executed fine without any issues. I use my laptop with the new HP Thunderbolt G2 dockingstation, I never had any issues using this dockingstation before. After the update it was impossible to get the dockingstation back to work. The screen and all other ports refused to work, even the POST screen was not shown at the display when my laptop was connected to the dock. I tried multiple different settings in the BIOS according the Thunderbolt 3 settings and tried re-installing the drivers in Windows. All without succes. In the end I decided to roll back the BIOS to version 01.01.02 Rev.A and after the roll back everything worked again without a problem.

The description of the update notes that several changes according Thunderbolt 3 where made which probably caused this problem.

I lost the entire afternoon at work solving this problem. I think it is really unacceptable for a busseniss line product to suffer problems like this after an update.

Please let me know if I placed this announcement in the wrong forum.

Regards,
Max

Hello, we deployed several of these along with Dock G2, and no problems

The latest FW is 1.4.05 >> https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-zbook-studio-g5-mobile-workstation/188...

G2 Dock firmware has also been released >> https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-zbook-studio-g5-mobile-workstation/188...

Along with TB3 controller firmware >> https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-zbook-studio-g5-mobile-workstation/188...

You will also need an updated Secure Connect app >> https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-zbook-studio-g5-mobile-workstation/188...

And make sure you approve the dock in the secure connect app after updating it and connecting it.

Hello, thanks for your extensive answer!

I did not have the latest firmware installed at my dockingstation. After updating the firmware and installing the latest BIOS it worked without a problem.

SOLVED!!  I have HP Spectre x360 laptop brand new, 3 weeks old.

HP prompted me to update my BIOS and after I did my thunderbolt port wouldn't work, at first I thought it was my charging dock that went bad.  After reading around the internet I tried a suggested solution to rollback to the previous BIOS by holding the windows key + B and the power button thing, which did NOT work for me.   After an hour of more reading I found the option to make a BIOS recover disk on a second computer, but when I got to that link (link below) instead of clicking on the option to make a recover disk, I clicked on download the latest version and installed it again--yes, even though it was the BIOS update that originally caused my problem.  But it turns out the original update didn't take all the way or it may have gotten corrupted and THAT is what caused my thunderbolt port not to work.  Because after I downloaded and installed it again I noticed it took longer and seemed like the first time that screwed my port up was very short:  so I'm assuming the first time didn't install correctly or completely because this time it did and as soon as I downloaded and installed it my thunderbolt port now back working. 

The entire solution took a few minutes.

 I went here:  https://support.hp.com/us-en/document/c02693833

then scrolled down to:  "Recover the BIOS using a USB recovery drive"

then I clicked on: "Install the BIOS recovery file"

then a screen came up suggesting I download and install Assistant and then I chose the option "download and install now."

5 minutes later everything was back to normal.

I am wondering if all along it was just your BIOS updated was incomplete or corrupted like mine and by updating and installing the latest BIOS was what fixed yours?  I also thought I was going to have to update my dock firmware but it turned out all it was was my BIOS update didn't install properly when HP did it (it said it "installed successfully" but apparently it did not because when I installed it at the HP link it took a lot longer to install and when it was done and restarted my thunderbolt port worked immediately.

In any case I'm glad you got yours fixed too, your message helped me and gave me the idea to reinstall the latest BIOS!
