ThinkPad L390 Yoga (20NT0013MZ) & Thunderbolt 3 Dock Gen 2 135W (40AN0135CH)

Q: ThinkPad L390 Yoga (20NT0013MZ) & Thunderbolt 3 Dock Gen 2 135W (40AN0135CH)

I connect a Thunderbolt 3 Dock Gen 2 to my L390 Yoga with firmware 1.18 and the latest dock-drivers 10011. Then I try to make a firmware update of the dockingstation with firmware-version 3.1.61. After unpacking I start the "ThinkPad Thunderbolt 3 Dock Gen2_Workstation Dock firmware update.exe" with admin-rights. Then I get a the following warning: "Can't read Thunderbol controller version, Will skip Thunderbolt firmware update!". After clicking "OK" the updater continue until the next message appear: "Your dock has new firmware can be upgraded, please click [Update] to start firmware upgrade." and the Current Version shows: = <unknown>.If I click the update-button the programm continue until the message: "Firmware update completed!" appear. A click on the OK-button close the update-program.If a start the firmware-update program again the same error happens. The update-program can't retrieve the current version of the docking station. So is the update-program buggy? The installed OS is Windows 10-1903 with latest patches and the docking with the 2nd usb-c connector from above on th left side. I bought the Thunderbolt 3 Dock Gen 2 because the Lenovo tool "docking-search" told me, that there are 3 dockings compatible with ThinkPad L390 Yoga. So what to do?

Hello, all. First time poster. Thanks in advance for anything anyone can offer by way of an answer. My question is fairly direct: Will the Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W work with my brand-new P43s Thinkpad? If this isn't the best or right one, which external graphics solution should I go with? I'm looking for some nice "oomph" for gameplay, etc. Kind of an after-purchase decision (sheepish grin). I have 16 gig of RAM and an i7-8565U. Thank you.Glenn

Hi, I have  a Thinkpad X380 Yoga. The Thunderbolt 3 Dock will not charge my Thinkpad X380 YOGA, and a message saying that the dock is not providing enough power shows up on my minitor. I wonder if anyone have a solution to this problem. It does not make  sense to have to connect the Thunderbold AND the AC power to the Thinkpad, it should be just ONE Thunderbold cord. 1. My power brick is 135W, 20V-6.75A2. I am connecting the Thunderbolt to throuogh the port on the back of the dock.3. I have went to BIOS  and under power section, "disable the battary for technical service" and pwered it back on. None of the above solutions worked.

I have recently purchased both of the subject items.  I was informed via chat channels with Lenovo that the graphics dock would work with the X1 Yoga 3rd Gen.  However, upon connection, my Yoga recognizes that a Thunderbolt device has been connected but it does not recognize that a graphics card or USB ports exist.  Thus, my mouse, keyboard, and monitor do not work while connected to graphics dock.  I have downloaded and installed the drivers for the graphics dock but the result is still the same.  Does the graphics dock really work with the X1 Yoga 3rd Gen?  If so, is there a BIOS setting I must address to make this configuration work?

We have standardized our deployments to ThinkPad X1 Yogas, and in many case including this one, they are the second generation model. Because of the performance, we use the Thunderbolt 3 Dock, purchased directly through Lenovo. This setup is not unfamilar to use as we have deployed over 40 workstations in the same configuration. This morning, our team received a call stating that an end-users monitors weren't working. Upon reviewing, we found that the dock wasn't being recognized by the laptop, although the connection was there because it was charging the laptop. We went through the normal "rinse and repeat" steps of ensuring that the thunderbolt cable was connected to the correct ports on both the dock and the laptop, removing the connection, removing the power, rebooting the computer, reintroducing the dock, etc., but to no avail. We remove the dock from known devices hoping that it would spark it to recognize a new device, but it didn't. We removed the Thunderbolt Software completely, reinstalling it, and then reconnecting the device, and still, nothing. Our devices are set to automatically install critical and security updates both through Lenovo Vantage and Windows Updates, but, the only change made between the time it was working and the time it stopped working wasn't relative to the dock. To be sure, we rolled back the updates, then rolled back farther, but it still didn't resolve the issue. We then followed through with installing all Windows and Lenovo updates: ... Read more

In the last month I purchased a Thinkpad X1 Yoga 2G and the Thuderbolt USB C dock. Since the USB C cable that comes with the dock is too short to allow the dock on the right and laptop on the left (in laptop mode), I put the notebook in tent mode and all works fine---except... Everytime I power up from hibernate it starts beeping about once a second and does not stop. I have to disconnect from the dock, flip it to laptop mode (this is where the beeping stops), return it to tent mode, and then plug the dock back in. It seems that Lenovo, like everybody else, is rushing things to market with plans to fix bugs later (maybe). Any thoughts I how to stop the beeping?  The first time it happened I closed all the apps to reboot and it still was beeping. Thanks.

Hello everyone, I recently bought a Thinkpad X1 Extreme and I am now locking for a suitable Thunderbolt 3 dock. Although I've read a lot of posts about various docks I am still a little consfused about which one to choose. It seems like the following ones would all work with the X1 Extreme:1. Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W:https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...2. ThinkPad Thunderbolt 3 Workstation Dock (170W):https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...3. ThinkPad Thunderbolt 3 Workstation Dock (230W):https://www.lenovo.com/ca/en/accessories-and-monitors/top-tech/Thunderbolt-WS-230W-dock-US/p/40AN023... Please correct me if I am wrong but to me it seems as if the only difference between these docks is that the workstation ones come with two AC adapters each and a special Thunderbolt/Power cable to avoid using two different cables. Or are there any other technical differences? So if I am okay with a two cable solution couldn't I just use the Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W and connect it via Thunderbolt while at the same time use my 135W AC adapter to charge the laptop? Thanks a lot in advance.

Does the Thinkpad P51s support the Thinkpad Thunderbolt 3 Dock? I have the Thinkpad P51s with stock Windows 10 Pro and updated to latest drivers and Windows version and installed the latest Thinkpad Thunderbolt 3 Dock drivers. Attaching the Thunderbolt 3 Dock to the P51s as described in documentation, it charges the notebook, however, noting attached to the dock is recognized. I've tested with attaching USB flash drives, headphones, Ethernet, HDMI, and DP, but nothing is recognized nor are any warnings/errors displayed in Windows. While the Thinkpad Thunderbolt 3 Dock is listed as being compatible with the P51s and T570, the notebook order page does not list the Thunderbolt 3 Dock in any of the accessories lists. Lenovo Sales also confirmed that the Thunderbolt 3 Dock is fully compatible with the P51s.  However, I needed to purchase the Thunderbolt 3 Dock separately from the notebook order. What's going on? Has anybody successfully used the P51s or the T570 with the Thinkpad Thunderbolt 3 Dock? Or is this something I need to wait for full support via a future BIOS/driver update? Or perhaps my Thunderbolt 3 Dock is defective? Thanks,Boris

Dear community, I am running a Thunderbolt 3 Workstation Dock with my P72 and I am having a hard time to get some of my realtime USB devices to run properly: (1) 1080p Webcams: I tested 2 devices (Logitech C930e and Microsoft LifeCam Studio) and both provide an unstable video stream, which is regularly interrupted by distortions. A lower 720p stream with another device (Logitech C270) works fine, though. (2) Oculus Rift Headset and Oculus Sensor: Does not run at all or with bad tracking performance. Those devices require a stable USB 3.0 connection to function properly. All of those devices run perfectly when connected to my Thinkpad P72 diretly. So chances are, that the Dock is causing the problems, I have the Dock's latest drivers (v10011) and firmware (04-0E-83_Rev_0083) installed. Does the Thunderbolt 3 Workstation Dock actually support fast USB connections (such as high definition Webcams)? Or is it rather likely that my Dock and/or the Thunderbolt cable are damaged?  I have been working on this issue for many hours now. So any advice is greatly appreciated. Cheers, Robert
