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.

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?

So I have a Precision 5510 laptop with Xeon processor, no 4K screen.  My question is about this thunderbolt dock TB16.  I have one HDMI out and was asked if I can make that work on 3 external monitors.  None are 4K.  Is that possible?  Can it function as extended desktop, not duplicated? And if so, is that 3 external plus laptop? Or is the laptop screen on of the 3?

 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. I'd say about 75% of the devices reach their destination and the user logs in for the first time as a user, not an admin, and the dock functions properly; monitors/mice/keyboard/etc. work. 25% of ...

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!!

Issue 1I purchased the ZBook Studio G3 + 2 months wait on the Thunderbolt 3 Dock to primarily connect 2 4K Samsung monitors.  When connected via the display port one will display at 4k while the other will only display @ 2560X1440.  I had bought a a couple of CableMatters thunderbolt 3 X display port adapters while waiting on the dock.  If I plug one of the monitors in using the adapter and the other into the display port both will display 4K.Anybody else having this issue? Issue 2After the computer goes to sleep only one monitor will wake up.  The NVDIA control panel still shows both connected.  Only way to get the second monitor awake is to shutdown and reboot. Issue 3I have the displays configured to go blank after 1 hour.  Once this occurs and I enter my password all of my open programs are displayed on one screen rather than on both.  This would be normal if you have undocked and re-docked a laptop. Issue 4If the laptop is opened while docked. One display goes blank and one is duplicated with the laptop screen.  This is not typical docked behavior.  I moved from an  Elitebook 8540W with dock.  I'm really questioning my whether this was an upgrade.

Hey There We have bought 15 Studio G3s and docks to go with them We have ran into issues with about 40% of the docks. Not sure if its the docks or laptops causing the issues. One laptop tries 3 diffrent docks, USB and Ethernet wont work. Another laptop will randomly BSOD, if the dock is even touched it will BSOD as well. I've gone though all the posts about these issues from last summer but nothing really seems to help. Is there a newer fix that I am missing somewhere? Thanks Josh

I've been experiencing general stability issues with the ThunderBolt 3 dock. I purchased Extreme X1 for work because of the impressive specs and portability of the device. Overall I've been very pleased with the performance and build quality of the device and Lenovo's software suite makes keeping everything up to date really easy. WIth that said, I've had LOTS of issues with general stability of this product. It appears to Lenovo had issues with the discrete graphics (Nvidia Geforce GTX 1050 ti) which may have mostly been resolved with the latest update. I'm on a fairly recent version of Windows 10 (1803). When using the Thunderbolt 3 dock I still experience lots of issues where the device freezes or becomes unresponsive when docking or undocking. Often times I must force power off the device completely because the device is unable to wake from sleep correctly when docked. I have not tested whether device itself is unable to wake from sleep or if it's just because it is connected from the Dock. However sometimes the device WILL wake correctly but then certain functions will not work, notable USB data will not work often but will be powered (keyboard lights are on but can't use caps lock, for example). Or sometimes the VIDEO won't display at all (thunder bolt graphics issue with discrete GPU) however I can clearly see caps lock works on my keyboard. Note all mentions of keyboard here refer to a USB keyboard wired to the TB dock.  Also worth noting ofte... Read more

We received a new 5510 laptop that works great on its own, but when adding in the thunderbolt dock we experience odd issues

1. If the laptop lid is closed while connected to thunderbolt, the laptop will hang at the Dell bios screen.  If the lid is open while power turned on, the laptop boots up fine.  However, the BIOS screen is still not visible on the external monitors, only when the OS has loaded
2. Dell shipped a new dock which had no differnce, and then I uninstalled every single driver and downloaded/installed in order from Dell's website, including updated Thunderbolt firmware and BIOs

The laptop is running Windows 10 x64

2 things I have noticed:
1. In device manager, the Thunderbolt Controller 1575 is hidden.  Viewing hidden devices and opening this controller states:
"Currently, this hardware device is not connected to the computer (Code 45)"  The resources tab states that there is a problem with the device
Of course, reconnecting makes no difference.  I have also unplugged all peripherals from the dock to make sure there was not a conflict
Second, in device manager, there is no listing (visible or invisible) for  ASMedia USB 3.0 Extended Host Controller Driver for Dell Thunderbolt Dock, regardless of uninstalling it through Add/Remove Programs and re-installing.
One more note - I am able to work normally after booting with the lid open successfully and then closing the lid.

A:Precision 5510 issues with Thunderbolt dock

I have the exact same symptoms with the same hardware (precision 5510 & WD15). the computer will not POST when it is either started or restarted with the built-in display closed. If the lid is open... all is fine. Ohh.. and when you do try to start/restart with the lid closed, i get a 2 orange, 7 white blink code. it will continue to repeat this until I open the lid and press the power button. This will then cause the unit to successfully POST and boot up.

I have three ZBook 17 G3 that I cannot get a Thunderbolt dock installed correctly on. The first does not seem to want to install the thunderbolt driver, so that one's fun. The other two are having a different issue entirely. I have read multiple threads here about similar issues, and none have offered a solution for my situation.I have tried the latest BIOS, I have tried an older BIOS, I have downloaded the drivers and firmware(which won't install because it doesn't detect the dock) Whenever I plug the dock in, Windows installs the drevices, but gets stuck and winds up with a "Base System Device" that it cannot find a driver for. I have tried three different docks, and three different cables. All have the exact same result. Is there an obscure driver that I need to download to install that is not obvious in all of my searching? Any questions or clarifications, I'm happy to respond. -Keith

I am using a Jabra UC Voice 550 Duo USB headset (Skype model) with Windows 7, for business communication. Or, at least, that was the intent: The reality is that if I use any ports on the docking station, I lose connectivity in the middle of a call. Several Skype chats started out okay, and then the microphone on my end simply stopped working (I could still hear the other party.) Also playing audio (Youtube via Google Chrome) has also resulted in eventual loss of playback. I have had to plug the USB headset directly into the laptop, in order to obtain glitch-free audio (via the on-board Intel USB root hub). The ASMedia USB root hub in the Thunderbolt docking station seems to be the culprit: I have two HP Z24n monitors plugged in via DisplayPort, and it makes no difference if I use USB ports on the monitor vs. directly plugging the headset into the Thunderbolt docking station itself. Since the laptop has limited USB ports, I would like a solution to this problem, please. The ASMedia root hub is running on driver version 1.16.33.1, dated 04.02.2016. One last thing: I got driver software for my Z24n monitors on CD-ROM, but hardly any notebooks are shipped with CD/DVD drives these days - and I could not find an online copy of the software, so I could install the display profiles.

We purchased a new X1 Carbon 6th Gen with the new Thunderbolt 3 Dock Win 10 1803 and have had all kinds of problems. Bad enough to consider other brand alternatives. All Lenovo drivers are current, we updated the firmware and drivers for the dock. With that we still have the following problems and dont know how to resolve them1. The network connectivity from the dock to laptop with USB-C loses connectivity on occasion. Also when the user shuts off the laptop, comes back and turns the laptop on, no network connectivity is re-established. The only way to fix this is to unplug the USB-C cable and plug it back in. Sometimes that will lock up windows and we have to do a hard shut down and start of the laptop. 2. Running the display out from the dock is not always reliable. The monitor will turn off randomly. To bypass this issue we have to just plug the monitor directly into the laptop. 4. Occasional random bluescreens with a stop  code DRIVER_VERIFIER_DMA_VIOLATION. This error is related to bad drivers.Are we missing something. Is there anything we have to set in the BIOS to resolve these problems? I've been reading up on this dock and a lot of people are having problems with this dock and carbon 6th gen laptops

If you check display settings I'm unable to increase the resolution to 4K. I've updated all drivers on the T570 including the display driver and thunderbolt docking station driver this morning and the system still fails to power dual 4K. I brought back the X1 I used previously and it powers the screens normally. I checked the specs of the T570 and its identical to the X1 as far as processor is concerned and the model page claims the USB-C port on the T570 can power dual 4K. What else can I try?

We have a Dell Precision 5520 that uses a TB16 docking station that all of a sudden is having difficulties connecting to our VPN. It was fine earlier in the day. We tried clearing the DNS cache and tried a winsock reset. THe drivers are up to date and everything. 
Also tried to reboot the computer multiple times.
Even tried a K17A Dock and had the same issue.
We were finally able to get the computer to connect to the vpn once we used a usb net adapter to plug the ethernet cable into.
Tried plugging the usb adapter into the computer directly and into the dock. It worked whether it was directly connected to the computer or the dock.
It only does not work when we connect the ethernet cable to into the lan port on the TB16 and K17A dock. And only for the one computer.

This is mainly when the notebook is at the thunderbolt docking station.I found out, that as soon as I connect my notebook to the docking station more or less all app-processes suddenly move over and start running on the GPU. The CPU has virtually no load.Why do all processes start to run on GPU when the notebook is connected to the dock? Is this an issue or is there a good reason for this behaviour?My Notebook and Windos has the latest drivers/bios and updates installed.Regards,Sebastian

Hi,I have a Thinkpad P50 and today my Dell Thunderbolt Dock arrived.Unfortunately, it doesn't work  (= it is not recognized in any way), although Dell specifically says that the dock also works with non-Dell Thunderbolt 3 machines. I have installed the Thunderbolt software from the P50's driver site and updated to BIOS 1.17.Lenovo released an "Intel Alpine Ridge Thunderbolt Firmware" for the P70. But there's no such firmware update on the P50's site, just the Intel Thunderbolt Software from November.The 1.17 UEFI/BIOS Update says it fixed a Thunderbolt issue, but apparently not mine Has anyone ever gotten some Thunderbolt 3 device working on the P50? I just hope this will be fixed soon, because the Thunderbolt dock seems to be the only convenient way to drive three 4K displays with the P50 (2 via Thunderbolt 3, 1 via miniDP).

We recently started using Bitlocker with a PIN at startup. On all our laptops using the "old"-type dock, that you click your laptop into everything is working fine, the users put the laptops into the dock, turn it on, type in the Bitlocker PIN using the external monitor and keyboard, and then processed into Windows. Our problem is with everyone using the new Lenovo ThinkPad Thunderbolt 3 Dock. When the users connect the laptops to the dock using the cable and then power on from the dock, the laptop will power on (the LED in the ThinkPad logo lights up) but the monitors and keyboard connected to the dock is not working, and then after some time the laptop will power off again. We currently use a workaround where the users power on, type in the Bitlocker PIN and login to Windows before connecting the laptop to the dock, but this not a proper solution. We have Enabled both "Thunderbolt(TM) device" and "USB device" under "Support in Pre Boot Environment" in the "Thunderbolt 3"-menu in BIOS, but it still doesn't work. Have anyone else experienced this problem?

So I have an X1 Carbon Gen 5 (Kaby Lake) and the Thunderbolt 3 Dock Gen 1 (40AC0135US). I bought two 4k monitors and after several frustrating hours figured out that the Gen 1 dock can't output 4k on two externail monitors at 60hz, this appears to be a dock limitaion only. I see that you now have a Gen 2 dock (40AN0135US) that says it will do 2x 4k @ 60hz, only problem is that every compatability cross refrence I can find does not say the gen 5 X1 Carbon supports this new dock. I don't see a good reason for it not to be compatiable, but wanted to find out for sure one way or the other before I bought it, as it is not cheap.

Hello all,I bought a Yoga X1 2018 and during the shop they suggest the Lenovo Thunderbolt 3 Dock. Since I thought that having to disconnect only one cable when bringin the laptop from the desk to the meeting room would have been useful, I bought it.With my disappointment I setup everything and I did some tests on the laptop just to discover that the performance of the laptop when powered through the docking station are 1/3 with respect to when it's powered by the 65W power supply and 1/2 of when the laptop is on battery... (234pt vs 640pt vs 563pt | dock/65W/battery)Now since the docking station has a 135W power supply, I really can't think that this is an issue with the supply from the docking. Also since the laptop is even faster on battery I really don't understand how it could be related to the power supply... anyway I've connected both the 65W power supply and the docking and the performance are back to normal.Is there anyone who can suggest me what's going on or how to report this to Lenovo?

As the only docking solution available and moving from a more traditional dock, its less than suitable.  HP needs to make a longer cable and the end that connects to the laptop should be at a right angle.  The cable is so stiff and thick it takes nearly 4" to make the turn.  HP makes it impossible to find this out how long the cable is with out purchasing and at that point your stuck with it.  Hardly a customer satisfaction issue they should want to propigate!

I just picked up the TB3 dock and all seems to be working, however it is not charging my laptop using the included Thunderbolt/Power combo cable. The power light shows on the dock, and connected devices work on laptop, but no power. Any ideas?

Love the concept of the thunderbolt 3 dock, can't fathom how it was designed though.  On my zBook 15 G3, the power and thunderbolt ports are on the right side of the laptop.  The dock has the cable port on the left rear side, completely crossing over all the ports when you put the dock on a desk with the back facing away from  you.  Then they ship a cable that is barely long enough to put the dock directly behind the laptop and connect it.   Where do I buy a longer cable HP, please!

I connected my P1 to my existing Thunderbolt 3 dock and to my pleasant surprise, the system was in charging mode when the system was off. I thought that the unit could only charge through the slim power connector port, but it seems that it will also charge through the Thunderbolt 3 port when the system is not running.

I've set up my Thunderbolt 3 dock. I notice in the status, it shows "94% available (plugged in, not charging)". It has been like this for the past two days. Does the battery have to reach a certain threshold, before charging? Or is this normal? My last dock, with the 8570W would always charge to 100%.

I have an X1E and a Lenovo Thunderbolt Dock 3 (40AC0135AU). I have noticed that when plugging the dock into the X1E it's temperatures increase. Additionally the top surface where the thunderbolt 3 port and charging port are located becomes quite noticably hot.  I only have an ethernet cable, and a USB speaker plugged into the dock, and also have the X1 135 AC charger plugged in. I have tried plugging the Thunderbolt cable into the front and back of the dock (only the rear of the dock provides charging), but no difference.  Anyone know why the increased in thermals? Is this just what happens when you use Thunderbolt with an X1E, or this dock?
