T460 in Dock with Windows 10 Does Not Always Transition to External Monitor

I have a T460 with Windows 10 Pro. The machine is normally connected to the Ultradock and an external; monitor. When the T460 is in the dock the cover is closed, and I use both an external keyboard and mouse.


The problems is that about once in 10 starts, the machine does not transition to the external monitor. I always see the Lenovo logo ion the red box, but about 10% of the time, the screen is blank after that.  I need to kill the computer by holding down the power buton on the dock until the computer goes off. When I restart the machine, 95% of the time it will work properly.


I have used Thinkpads in docks in this manner since my old X21 and Windows XP. I have had a number of Thinkpads, both 12 and 14 inch, with XP and Windows 7 since then, and all worked in the respective docks with external monitors. I have never had this problem with the T460 until one of the Windows 10 updates.


Is there a solution?
