How can a laptop that cost 1800 euros plus an expensive dock has this stupid problem.
I choose lenovo to avoid this kind of sh*t's....
I bought the 3 year warranty, and I feel completely conned...
How much time do I have to wait to get a solution from this major "chinese" manufacturer?
Sorry DELL, sorry for not choosing you, but soon I will emend my decision... geezz

Meanwhile another Problem appeared: USB is not working at my Dock. Which kinda starts to defeat the purpose of this thing. Another thing i have to look into.
I have to say: I am very happy with my Lenovo machines at home. But: They are all used, older Models: x220 (Best Laptop ever made!) and my daily driver the t440p. No Problems, all running absolutely fine and the Dock is simple and awesome - they never let me down. I am afraid that the t460 series will be the the last line of lenovo notebooks i will buy as a private person. I totally disagree with the modern interpretations of the thinkpad line.
Maybe its time to tell the IT department to get me a new Dock ...

it is a well known problem. There are quite a few topics here about this L1 throttling problem. Lenovo said in a thread here somewhere that they managed to reproduce the problem and are looking into it. Lets see what will happen. Btw i also added a smal fan that blows under the laptop between the dock and it helps a bit i think

Nice, thanks for pointing this out here.
Im on Windows. Unfortunately i use Hyper-V ... So disabling it is not an option. I guess i go with my trusty fan until the fix is there.

I have the same problem.
T480 and ultra docking station. Laptop seems to work OK when not docked.
Once docked runs fine for a short while then power limit gets stuck around 7W-10W ( limited to 7W while writing this ). Temps are 50-55 Celcius while limited. Only sure way to unlock the limit seems to be turning off the laptop.
I've had the laptop motherboard changed 3 times and the dock once. Last dock also randomly limited CPU to 200MHz or 400MHz frequency. This newer one seem to be content on only power limiting so far *knock on wood*.
I really hope there will be a fix soon. I need my dock to connect extra displays, but at the same time runnin at max 1/5th performance is really fustrating.
Edit ( 2019-09-27 ): Ran few Cinebench r15 runs while the system is limited. Scores were from 99 to 148.
Here's the high score:
