L14 stopped outputting video over USB-C

2021-01-05, 20:52 PM

I have an L14 that is used primarily on a Lenovo USB-C docking station.  Yesterday it would no longer output any video to the monitors connected to the dock, windows does not even detect the monitors.  The internal display works fine as well with a monitor connected with HDMI.  The dock will provide power and a network connection, but no video.  I have tried multiple docks and even a USB-C to displayport adaptor and there is no video output.  I even tried reinstalling windows with no luck.


Does this sound like a hardware issue?  I have a warranty on this machine.
