T480, USB-C to Thunderbolt & Mini displayport

We recently moved from the Lenovo T470 to the T480. We have purchased two of the T480's, with both we have the same issue;

The adapters we have used for the T470, won't work with the T480's. The ports do work with our usb-c displays. 


Some background information, the monitors we are connecting too are both from Apple, Thunderbolt Display and the Cinema Display. We have no issue with the T470, with the same adapter. The adapter we are using is a Apple Thunderbolt 3 to thunderbolt 2. We have also tried other adapters from some aftermarket sellers. 


What we have tried already:

Several adapters, none work. 

Both ports

We have tried deactivating the security in the BIOS for the USB-C, just to make sure we tried everything, but also no succes. 

We have spoken to our Lenovo reseller for over an hour, but no succes or tips.. 

Checking the thunderbolt software, if it gets recognized or anything but no.


If anyone could provide some insight into this issue would be greatly appreciated. 


Thanks in advance!

Hi Finaps,


Welcome to the community forums.


We appreciate all the steps that you've tried. We would suggest uninstalling the USB driver and update the BIOS,chipset and USB driver of your laptop. You may download the updates here:
