Thanks for posting your question here! First, can you say which Graphics Adapter you are using? Have you used it before or is it new? Does it work when plugged into the laptop directly? Regarding the docking station, can you say more about the issue? How is it connected? What is the status of the disk installed?
With these additional details we’ll be able to figure next steps,
Thank you,
I have a problem with lenovo L420 laptops being atatched to the usb port replicators. I had different problems for example there is a delay in the external monitor, network issues, keyboard issues. But the main issue is that the laptop freezes when it is connected to the replicator. Can anyone help please?
