Thinkpad USB3.0 dock
I have a Lenovo X1 and Thinkpad USB3.0 dock. The external monitor has stopped working, with an error message "check connections". I have checked all connections - replaced the dock to monitor video cable but Windows does not detect an external monitor.
I had this error a month ago, but after a trip away with my laptop, I came home, reconnected and all was well. No such luck this time.
The USB is working fine, as it is also my internet connection.
any ideas?
thanks in advance
Philip
