X1 Yoga + New ThinkPad Thunderbolt Dock + 2 Displayport-connected Monitors = Not Working

Q: X1 Yoga + New ThinkPad Thunderbolt Dock + 2 Displayport-connected Monitors = Not Working

Not able to get two monitors (Samsung S27E450) plugged into a ThinkPad Thunderbolt 3 docking unit to work with my X1 Yoga (Gen 2). Montiors connected to docking via DisplayPort cables. Windows 10 shows the monitors showing up as "Generic PnP" so something is being recognized. Tried deleting the device in Device Manager, reboot. Not finding the drivers on the Samsung site. Any help appreciated.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Everything is working except - no sound via monitor.  Have updated audio drivers,  Suggestions??

A:Yoga X1 ThinkPad thunderbolt LG Monitor Connected via DisplayPort - No Sound

You might need to enable it. 
 
With the monitor connected, turned on and displaying your computer's desktop:
 
Right click on the speaker icon in the taskbar and select "playback devices." 
 
In the white area of the dialog box, right click and make sure both "show disabled devices" and "show disconnected devices" are both checked.
 
Right click on the various playback devices to make sure they're all enabled. 
 
If you start something with audio, you should see the little green "meters" bouncing on one of the devices. Right click that device and set it to default.

Hi, I  got Yoga 920 with Lenovo Thunderbolt 3 Dock that is connected to two 4k Samsung monitors. Just recently when I put Yoga 920 to sleep the monitors will switch off, but in 10-15 sec start looking for a signal.Basicaly screen goes to black (looks like monitor is off) and then in 10 sec it switches on a show blank screen with input name on (DisplayPort) and than it goes off and in 10 sec on with input name ..... this keeps cycling on and off. This is happening on both monitors. It's strange as it used to work fine untill recently (apropox 1 week ago). Im on latest bios with Yoga 920 and latest firmware for Thunderbolt 3 Dock and Lenovo Vantage says my system is up to date. The windows recently updated to Windows 10 (1709), not sure if that is related. Any help how to fix this issue?

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

 Hello all, I am a solutions architect trying to solve an issue which I have never heard of before. Though others users are having this same issue, my experience has been different then what they have seen. First,The following are the Security options for Thunderbolt devices as per user guide

No Security: Allow Thunderbolt devices to be connected automatically.
User Authorization: Allow Thunderbolt devices to be connected after user authorization.
Secure Connect: Allow Thunderbolt devices to be connected with a saved key that has been approved by the user.
Display Port and USB: Allow only DisplayPort-compatible devices and USB devices to be connected. Thunderbolt devices are not allowed to be connectedI don't think this is entirely true or at least does not apply properly each time. My scenario:T480, T580, or Yoga x1 3rd genImaging with a standalone MDT environmentDevices come pre-configured from Lenovo with Thunderbolt 3 Security Options set to "User Authentication" Installing all the drivers in the latest SCCM driver packs that Lenovo offers - though the x1 3rd gen driver pack was missing on the site this morning. On some devices, this security option seems to do absolutely nothing. MDT uses the local "Administrator" account to perform post-OS items.

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.

I have two 27" 2560x1440 60hz monitors that are plugged into the new Pro side-connect dock (40AH) with a new T480 (Intel 620 integrated graphics) in Windows 10 Pro. I can get either monitor to work fine with the dock individually, but trying to run both simultaneously by extending or duplicating the desktop between them seems to fail as selecting either option under Display Settings just makes the primary monitor black out for a few seconds then come back - the secondary monitor stays black.  There's no error msg or popup that would help me investigate further unfortunately. I'm trying this with the T480's lid closed, and I'm running the latest 1.14 BIOS update and latest Intel HD graphics drivers. This setup worked fine on my old OneLink dock and X1 Carbon previously, so I don't think it's an issue with the monitors themselves. Anyone have a similar setup with the new Pro dock that's working?

I purchased the Thunderbolt 3 Dock with my Yoga 920 as it was listed as an accessory during my Yoga 920 purchase back in November.  I finally got around to setting it up and I can't seem to get the power button the dock to turn on my laptop.  The button glows white when my laptop is plugged in but the button will not turn the laptop on.  I have my power button option in Windows set to "when i press power button while plugged in, the laptop will go to sleep."  So even while the laptop is connected to the dock via USB-C/thunderbolt and the laptop is on, when I push the power button the dock, it doesn't put the laptop to sleep either--it does nothing. Googling around, I see there is a newer dock called USB-C dock and it's listed as compatible with the 920 whereas as the Thunderbolt 3 Dock is not listed as compatible.  Could this be the issue?   I also have thunderbolt software installed and it detects the dock in the software. I need some help please!

Dear all,

Both are running fine. But it is impossible to start the PC when the dock is connected: The screen freeze at the red square LENOVO display from the Bios, windows 10 pro doesn't start.

I have to disconnect the dock, et relaunch the PC to enable a normal start. After the start, I can reconnect the dock.

I updated all drivers, flashed the bios, latest FW of the dock and even resetted Windows, but without success.

Lenovo support wants to change the laptop (!), it's brand new!

I thought maybe one of the topgun member of this community might have a better idea.

When a Windows 8 ThinkPad Yoga is connected to a ThinkPad OneLink Pro Dock (Model DU9033S1) which has a sound cable placed into its headphone jack, every few seconds the sound will alternate between the laptop speakers and the docking station. It appears that the connection to the docking station is briefly lost (sound comes from laptop speakers), and then re-established (sound goes to docking station). However, during this "disconnect/connect", all other aspects of the docking station are unaffected (video, network, USB).
 
Updating BIOS, audio drivers, dock drivers & firmware have had no impact. If sound cable is removed from dock, then behaves normally (sound goes to dock only). Happens with multiple Thinkpad Yogas and multiple docking stations.

Hi all, In the past few days my laptop slowly degraded, starting with docking station connectivity not working (but does work with other laptops), then HDMI port not working (HDMI screen and cable works with other laptops), and now system no longer charges. Current status is that all USB-C ports (including charge) and HDMI port and not functioning. Computer doesn't charge when it is off, too.  I've looked at multiple solutions and threads on this website without any real solution. I've already tried - - run Lenovo Vantage a few times to check updates. Did the same on the Lenovo product website (using auto-discovery of serial #), everything is fully updated- Turned on/off Thunderbolt Service (on the Windows 10 control panel) - I turned it on and automatic but it always returns to Manual- Searched in the Device Manager for Thunderbolt (anything) - it's not there- Uninstalled and re-installed Thunderbolt software from the Lenovo website (both controller driver and FW, file names n1nta05w.exe and n1nth08w.exe)- Went to the BIOS/Configuration - enabled and disabled again all Thunderbolt related options - Used Paperclip to do hard reset using the emergency reset button Any ideas what left to be done?  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.

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.

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

Hello everyone,  I would like to connect 3 external monitors to Yoga 260. I found out that conection of 3 external displays is feasible. It is associated with turning off the native LCD, whcich is OK for me. I would like to use ThinkPad OneLink+ Dock (40A40090XX). The docking station has 2 DP and 1 VGA. The issue is I'd rather use 2 DP from docking station and one DP which is on board Yoga instead of VGA. Is such configuration possible? I would like to figure it out before I will buy the station. I've found document: https://support.lenovo.com/uu/en/documents/pd029622 , but there is nothing on using docking stations' DP and native DP in one configuration, simultaneously. Whether it is because on board DP will be disabled? The alternative is MST (eg. http://www.club-3d.com/index.php/products/reader.en/product/multi-stream-transport-mst-hub.html). Both devices are at a comparable price, and if I had confidence that the docking station will work with onboard DP simultaneously, I would choose it.  Thank you in advance, best regardsM

Since no one has replied, I would like close this discussion.  Still someone might benefit for the information, that: - I have purchased and tested ThinkPad OneLink+ Dock- it works with 3 external monitors using 2 DP from docking station and one mini-DP from Yoga itself- working configuration is as follows: 2 displays are connected to OneLink+ Dock with one active DP to DVI converter, one passive DP to DVI converter and the last one (Yogas? port) with active mini-DP to DVI converter- I didn?t try to use for example 2 or 3 passive DP to DVI converters (but I guess that 2 should do the job, but 3 will probably won?t work)- when OneLink+ Dock is attached, the HDMI port in Yoga is not working! (the information one can also find in BIOS, but no materials on-line) Best regards,Maciej

Hi There, I'm having trouble with a Lenovo P52 with a Thinkpad Thunderbold 3 Dock. When I Conect my dock to my laptop it wil ask if i want to allow it. (It always asks strangely. Even if its in managed Thunderbolt devices.)  After pressing ok the problems start.-Shortcuts are flickering on the Desktop and in the taskbar.-Not being charged-No Mouse & Keybourd-No Ethernet.-External screen does work but with above problems. Additional information:-With only the powercord and usb-c into the Lenovo Laptop and nothing else in the dock it stil gives the same problems.-Tried with difirent cables.-Tried other Docks but same problem. (Docks that work with other Lenovo laptops)-It works somtimes. once every 5-10 tries. But fail right after trying again.-No Faults in Lenovo center. Product information:Lenovo Vantage InfoLenovo Thinkpad Thunderbold 3 DockModel Number: DBB9003L1 I have updated the most drivers that would be needed for the thunderbolt & Lenovo but nothing seems to work. Is there anyone who has been batling this before or somone who could help me?

I have narrowed the issue down to a software issue.  I have tried resetting the dock, the computer, updated to the newest driver as well as even replacing the dock itself.  I had an extra and thought the dock ports might just be dead but the new dock doesnt work either.  I have also tried both ports on the PC in order to rule that out as well.  Does anyone have suggestions?  Thank you in advance!!

Hello! Im having a little problem with my docking station. ThinkPad Mini Dock Series 3. Seems like the DisplayPort does not work. I use dual 1440p monitors from Phillips and want to connect both with DP as the DVI is single-link only. I have one of the monitors plugged in the MiniDP on the side of T430 so i got that working wich is nice.  Is there some kind of firmware or something i need to install to get the DP working on the docking station? Cant remember i have ever done this and as far as i know it ha never worked... Always used it with a single 24" monitor with VGA. Thanks.

A:T430 with ThinkPad Mini dock series 3 DisplayPort ...

This issue is driving me crazy!  I bought new DisplayPort Monitors for T430s ThinkPads using the Mini Dock Series 3 dock.  I have 4 identical laptops.  Same software and drivers with two Monitors.  One on the Dock DisplayPort and the other Monitor on the PC Mini DisplayPort.   Three laptops work perfectly.  The forth one blinks! I do have a newer T430s with the Invidia Graphics card that has the same symptoms, but I have come to the conclusion that Lenovo does not support multiple monitors with that version.  Lenovo, Please tell me there is a firmware update for the Type 4337 Mini Dock Series 3 dock.  I saw the link for the T540 dock firmware update.  Will it work on the Series 3 dock?

Is the new ThinkPad Thunderbolt 3 Dock compatible with P50? Dock details page (https://pcsupport.lenovo.com/cz/en/solutions/acc100356) only list P51s, but not P50. But P50 claims support for Thunderbold 3. If yes,  can I connect Ethernet LAN over the dock? And what driver I need to install?

I have a new P51, 64 GB ram, SSD hard drive. Ihave a docking station at work and one at home. The one at home has a 6 TB Seagate BarraCuda pro USB3 drive attached. When I dock the laptop at home, the system will not boot. It gets to the bios boot sceen and stays there until I turn off or disconnect the USB drive. Once I do that, it continues to boot and if I turn the USB drive back on, it works fine. If the drive is my old 1 TB barracuda, it boots normally.
