Thank you for posting!
My impression based on your description and the section within which you have posted in our support forum is that you are using a Plugable TBT3-UDZ docking station → https://plugable.com/products/tbt3-udz Please correct me if I am mistaken.
Presuming for the moment that my impression is indeed correct, based on your description of the behavior our next step is to get some additional information.
Can you please send an email to our direct support email address → firstname.lastname@example.org with ‘For ticket #- 388988’ in the subject line that contains the following information?:
1.The Amazon Order ID number for your TBT3-UDZ purchase
This information is available from → https://amazon.com/orders
2.While the TBT3-UDZ is connected to your Lenovo laptop (even if not working as expected), the output of our diagnostic utility PlugDebug → https://plugable.com/pages/plugdebug
This information will help us to determine the next steps.
Note, if having the TBT3-UDZ connected to the laptop prevents gathering the PlugDebug, it is okay to disconnect the TBT3-UDZ from the laptop when gathering the information.
