X1 Carbon Gen 6 - USB C external monitor issues

2020-08-13, 14:19 PM

I have a an X1 Carbon Gen 6 (20KG0022US), and I want to connect it to my external monitor with a USB-C 3.1 cable. I want to do this because this will both serve as my external monitor & charging cable.

It generally works, but the weird thing is that it only works well when the laptop is charging. Once the laptop is fully charged, it starts to intermittently disconnect and then reconnect (once or twice every minute).


Am I using the wrong cable? Is there some firmwire update that I need?


Thanks for any and all help!

Use the Vantage application to update your BIOS. The latest BIOS version 1.49-1.21 fixes this issue.
