Hello Jay, thank you for your interest in our Community.
I’m quite sorry to hear about that. From what I can see, there seems to be something odd with the connectivity. I understand that you’ve tried two different docks: but did you make sure to try the provided and specific USB-C cable from the respective dock? I would also recommend you to try the dock on another laptop in order to confirm if the issue is isolated to this particular unit, or perhaps other ThinkBook 15 G2.
I look forward to hearing back from you,
Emmanuel B.
