Nothing works on start up of TBT4-UDZ

Just tried to set up a brand new TBT4-UDZ to connect to my Dell XPS using the Thunderbolt 4 cable and nothing seems to work: data cable/ monitor/ external keyboard & mouse are all dead. Only the white power light for the docking station comes on. I’ve updated the drivers (install_usb_win11_11013_20_07272023_08042023), restarted both the laptop & TBT4, still nothing.

Everything works fine with my old Plugable 3.0 (UD3900).

Hello,

Thank you for posting! I am sorry things are not working as expected while using your TBT4-UDZ docking station, and I would be happy to help.

Based on your description of the behavior, I have one quick question for you.

Can you please confirm that the included Thunderbolt 4 cable is connected to the single Thunderbolt 4 host connection port located on the front side of the TBT4-UDZ docking station?

I ask because if the Thunderbolt 4 cable is connected to the USB Type-C peripheral port on the back of the TBT4-UDZ then the dock will not work as expected.

For your reference, I have included a photo (just below my signature) of the TBT4-UDZ with the Thunderbolt 4 host connection port highlighted in red.

Apologies again for the frustration, and thank you for giving us the chance to help!

Yes, I plugged the Thunderbolt 4 cable that came with the unit into the front of the docking station.

Hello,

Thank you for getting back to us with the confirmation in regard to how the Thunderbolt 4 cable is connected!

Given your current description, our next step is to get some additional information.

Can you please send an email to our direct support email address → support@plugable.com with ‘For ticket #- 425296’ in the subject line that contains the following information?:

  1. The Amazon Order ID number for your TBT4-UDZ purchase

For your reference, an Amazon Order ID number has seventeen digits (separated by two dashes), and that information is typically available from → https://amazon.com/orders

  1. While the TBT4-UDZ is connected to your computer (even if not working as expected), the output of our diagnostic utility PlugDebug → https://plugable.com/pages/plugdebug

That information combined will help us to determine the next steps.

When I plugged the TBT4-UDZ back in again, it worked! I presume the driver updates and a further/ prolonged shutdown of the TBT4-UDZ got it to work.

I have found that a monitor (Benq BL2411) no longer works (it seems to be recognised as being connected using HDMI but no image - just a black screen)? I have another Benq (BL2405) that works fine with the TBT4-UDZ.

Hello,

Thank you for getting back to us with the update, and I am glad to hear that we have made progress.

I am afraid that I cannot be sure of the cause of the remaining unexpected behavior based on the description alone.

As a result, our next step is to get some additional information.

That information combined will help us to determine the next steps.
