Lenovo ThinkPad Ultra (Pro) Dock + ThinkPad X270 (20K6) + Dell UZ2715H



We have a problem with 2 laptops (ThinkPad X270) that "freeze" on the LENOVO logo when using Lenovo Ultra Dock with monitor Dell UZ2715H.

Display Dell is plugged by Display port ports and one USB 3.0 (9 pin - used for display integrated webcam) connected to ThinkPad dock.

When notebook turned ON with connected USB 3.0, computer freeze on LENOVO logo (To interrupt normal startup, press Enter) and work only when USB 3.0 disconected, or turned OFF and again Turned ON.


Firmware on Dock is 2.33.000


Any suggestion?

I am just going to guess that computer is trying to boot via USB, so you might try changing the boot order in the BIOS so that Windows Boot Manager or the HD is first.

It sounds like the same problem that is discussed here:


You might be able to avoid the problem by using an older BIOS version for your X270.  I have also read that other people are currently avoiding the issue by plugging their USB devices directly into the dock, instead of using the monitor as a USB hub.


I know that we are working on a BIOS to fix the issue, but I don't have any release date yet.
