Yoga 370 not charging through USB-C Thunderbolt 3 Dock

So I got a brand new Yoga 370 and just got me a ThinkPad Thunderbolt 3 Dock. I have connected it to my laptop through a Thunderbolt 3 (40 Gb/s) USB-C cable male-male 5A, which supports power supply up to 100 W. I have plugged in the dock itself with a Lenovo original cable of 90 W. I also plugged in a HDMI cable from the dock to my monitor.


After plugging in, my computer automatically installed the Thunderbolt software, package version It also says I have the Thunderbolt controller generation 15BF, firmware version 4.04, installed now.


Monitor works fine.


But my Yoga is not charging. I tried to restart the computer, unplug the dock, and I even installed the Lenovo Power Management software from the Lenovo website, which I assume is then the latest version.


Any ideas of what could possibly be wrong here?


It is a bit of a disappointment as I was hoping this would work perfectly fine right away. I spent some 50 dollars on the USB C cable and another 150 on the dock itself.

I'm having the same issue


I have:

Updated the software on my laptop

Updated the firmware on the dock

Used a differenct USB-C cable


The monitors and ethernet are working fine, but it is kind of ridiculous that I have to have two power adaptors (one for the dock and one for the laptop).
