Thunderbolt 3 Dock - Monitors not working

Q: Thunderbolt 3 Dock - Monitors not working

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 the time either nothing works, or only the mouse and keyboard. In testing, on all three device types, setting security level to none allows everything to work as necessary. However, setting "Display Port/USB" only allows our monitors to work - mice and keyboards do not. Is anyone else experiencing this issue in the way that I am? Not really sure how to proceed. What is the overall risk to turning off security? Is Thunderbolt 3 creating a trust relationship with the OS where you can navigate the host device going through the connected dock via USB or what? Thanks,

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?

I used the Lenovo System Update (v5.07.0074) and was prompted to download and install (was listed as Critical Update) the Firmware to my Dock.  As always, I closed all applications and sat as the Firmware downloaded. I got the expected prompt to ensure I was plugged in. I then watched as the upgraded prompted me to install. Installation completed and everything appeared to be fine.  I powered down the thinkpad and disconnected. Worked from the living room, then went back to the dock. Connected, and noticed that before I connected the White light on the power button was illuminated. Shrugged, and pushed the power button. Nothing. I un-plugged the Dock, got a cup of coffee, returned and plugged it back in. Nothing. I then noticed that none of the pass-through power was working on the dock.  So, I unplugged it again.  Unplugged everything connected to it, and held the power button down for 15 seconds in an effort. All of this at the recommendation of Lenovo Support. Who, by the way, was very nice and well spoken. Nothing we did worked. I happened to have another Thunderbolt 3 cable in my bag, and no change. I powered up my new X1 Yoga, and connected the cable. No power. This wasn't passing power at all. I confirmed the Intel Thunderbolt app was running, and confirmed that Windows was not even detecting the Dock.  Lenovo is sending me a replacement.

Since the last Thunderbolt firmware update the DP ports no longer work. No matter what settings you try, no signal is detected. The only way to use monitors now seems to be to use the front USB-C port and connect it to the first monitor and then use DP daisy chain from monitor 1 to monitor 2. We have 2 Thunderbolt docks with the Update installed and both have the issue. We have one with the stock firmware and it works flawless.  Anyone else having the same issue? Any idea how to fix?

Hello, My company recently purchased a dual 4k setup for a work station. The setup is the following:2 ThinkVision P27 monitorsLenovo ThinkPad Thunderbolt 3 DockT570 (Type: 20HA) I setup the monitors and docking station yesterday and was able to power the displays using a X1 Carbon 5th gen (i5 model type: 20HQ) thru USB-C without issue. I have a user testing out the desk now with a T570. I'm able to get one monitor to funtion at 4K and the other is running at 1080p. 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?

I have been experiencing issues with my USB keyboard on my XPS15 9550 w/TB16 Dock when the Logitech G610 USB keyboard is plugged into TB16 USB 2.0 port in the back.
The keyboard will hang, accepting no input. or may hang on a certain letter, thus producing an "aaaaaaaa" across the screen until the keyboard "comes back".
Keyboard seems to work fine while plugged directly into the XPS15 rather than the TB16.
I also have an external USB drive for backups that I use connected to the TB16, although seems to be functioning fine. I have not had a backup fail, so, I assume it is working fine.
I have tried downloading all of the drivers, and re-installing them in the proper order according to the documentation while disconnected from the TB16, and then connecting to the dock.

Is anyone else experiencing a similar issue?  Is it the dock or the 9550?

A:USB Keyboard Hangs/Quits working on XPS15 9550 and Thunderbolt Dock TB16 . W10Pro x64

If you happen to run Citrix Receiver, make sure you're running at least version 4.9, since earlier versions are known to cause USB issues with the TB16, although that typically presents as the USB ports not working at all.  If not, then there was also an issue with intermittent USB device disconnects that was eventually solved through a combination of drivers and firmware, so when you say you've downloaded all of the drivers, please confirm that includes:
- BIOS
- Thunderbolt firmware
- Thunderbolt software
- ASMedia USB Host Controller driver

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!

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.

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.

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!

Hi allWell we all now about the fan issue which is much better since the last BIOS update.Nevertheless I have sometimes fluctuation fan noise, although there is no load. 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

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?
