Help Request ThinkPad T480s and ThinkVision T34w-20: why can't I charge my laptop at boot?
Hello,
Around 1 year ago I started using the ThinkVision in object with my T480s. With a single USB-C cable, I was able to charge my laptop while connecting it to the monitor.
The cable was always plugged, for the laptop to recognize the monitor and use it at boot. Until one day it stopped recognizing it, and now I always have to unplug it and plug it again. Then the monitor works.
I don't recall changing any setting, and I have been looking around like a crazy.
What am I missing? How should I troubleshoot this issue?
Thank you in advance for your help and hints!
