Thunderbolt 3 dock Gen 2 and Thinkpad P1 lag

2019-07-09, 14:49 PM

Hi,

 

I've had for some time problems that when I connect my P1 via Thunderbolt 3, performance goes noticibly down, at least the video lags significantly. 

When I unplugg it it is fine, or when I plug it directly to monitor via HDMI it is also fine.

Only help is to restart Windows, but usually after I again plug out/in the dock I get the same problems.

I've spent already days by downloading all newest drivers (dock and video cards) and firmware for dock and BIOS, but it doesnt help. 

 

Any clue what to do?

 

Thanks

Same problem here. Can anyone help? I assume it is an issue with the dock?

This happened to me for the first time today. The only difference today was that I had my P1 on and open when I plugged in the dock. Then after it connected, I shut the lid and moved to my desktop monitors. I then saw the terrible lag when scrolling.

 

Normally I sleep the laptop before plugging it in or shut it down completely before plugging it in and don't have the lag. Today I shut down, restarted with it plugged in and the lag was gone.

 

I have a whole lot of other issues with this dock though. Plugging it in causes the "No battery is detected" icon to show up and the battery doesn't charge. And whenever I shut it down while on the dock it basically freezes and I have to press the tiny reset button on the bottom of the laptop to get it to turn on again.

I'm starting to see this more and more. When it does happen, it is after I sleep and then awake the system while docked.

I have the Nvidia drivers from 7/16/19 and the BIOS also released on 7/16/19 so I'm on the latest of everything.

I've had this issue too. I've downloaded all the new firmware for the dock, updated my computer through the Lenovo Vantage thing, and nothing helps.

The display is extremely laggy when plugged in, and I use the system for CAD which makes the experience terrible.

Does anyone notice that this lag is gone if you keep the thinkpad lid open instead of closed?

Yeah, that's definitely the case.
I was also able to reproduce mbinette's problem as well.
This seems to be the same issue-- I really wish a Lenovo rep would address it.

I have the same problem with the workstation dock on a X1 extreme. 

 

X1 Dock. 

https://www.lenovo.com/us/en/accessories-and-monitors/top-tech/Thunderbolt-WS-230W-dock-US/p/40AN0230US

 

100% reproducible.

 

1. Fresh reboot. -- is fine

2. Undock  -- is fine

3. Redock  -- terrible lag. System process goes at 5-10% all the time forever. 

4. Undock -- is fine

5. Redock  -- terrible lag. System process goes at 5-10% all the time forever. 

6. Reboot while docked -- is fine until I undock/redock.
