Thunderbolt 3 Dock Gen 2 with X1 Carbon Gen 5

Q: Thunderbolt 3 Dock Gen 2 with X1 Carbon Gen 5

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.

Hi!I just got a new "X1 Carbon 5th Gen - Kabylake (Type 20HR, 20HQ)" and a "X1 Carbon Thunderbolt 3 Dock". I have an external screen connected to the dock and it works fine (VGA connection). I also have an other monitor with display (DP) connection that I want to use. But my computer can't find the other monitor, only the one with VGA connection. Is there any easy ways to fix this problem?Best regards

I've been using a USB 3.0 Pro dock with my Carbon X1 5th gen. I wanted to updgrade my external monitor to an ultrawide - so I bought a Thunderbolt 3 dock. The dock will charge my laptop, but nothing plugged into it is detected, nor does it show up in device manager or in the Thunderbolt Software. I did install the drivers for the dock. I then tried a USB-C dock to see if I had different results - same problem. The dock doesn't show up in device manager, nothing plugged into it is detected. The dock does charge my laptop.  Any ideas what I can try to troubleshoot this?

I recently purchased the X1 CRBON 5TH Gen (2017)...type 20HR plus a thunderbolt dock.I connected them together with a Dell 28" 4K (@30Hz) screen (p2815q) connected through DisplayPort from the dock, plus a Microsoft keyboard and Jabra 510 USB speakerphone.Using the Windows 10 stock image from Lenovo, plus Office 2016, Chrome, Visual Studio, Skype,  and various other apps (putty, RDP, SAP GUI, others) the video performance was atrociously bad. Alt-Tab, which I use heavily would take 3-4 seconds to respond, switching between applications, Windows would freeze and sometimes crash, I would often get blank or black windows in Chrome and Office. This was on the embedded Thinkpad screen as well as the external monitor.I ensured Windows Update was up to date, as well as Bios, Drivers etc through the Lenovo companion app. So...I dove into the BIOS and voila! There is a switch that lets me change the Video memory from 256 to 512 MB allocated!I went to change it, and it would not change until I changed the setting:BIOS > Config > Thunderbolt 3 > Security Level = from "User Authority" to "DisplayPort and USB"I switched that setting, and then set my video memory to 512 MB, rebooted and voila!

The X1 carbon 6th Gen supports Thunderbolt 3, yet it is not listed as compatible with the Thunderbolt 3 Dock Gen 2. Anyone have an idea why? Also the ThinkPad T470s.
 
https://support.lenovo.com/us/en/solutions/pd500265
 
The X1 Yoga 3rd Gen and X1 Yoga 2nd Gen are listed as compatible. Perhaps it just means that the dock has been specifically tested with the listed models? Surely Thunderbolt 3 is Thunderbolt 3 and the dock should work with plenty of other Thunderbolt 3 machines?

I just got a new Carbon X1 6th generation (20KG).  I started using this with my Thunderbolt 3 dock (40AC), that I successfully used with my previous Carbon X1 5th Generation. There seems to be some compatibility issues here. After using it with the docking a while (apprx. 1 hour), the X1 suddenly started to continuously disconnect/reconnect from the dock (each 2-3 seconds), before it permanently was disconnected from the docking and would not connect at all.  When I disconnected the X1 from the dock and restarted (without connecting to dock) the X1 Thunderbolt software and devices/drivers related to that on the X1 "went crazy" and appeared/disappeared from the device manager continuously (each 2-3 seconds). I needed to enter bios and temporarily disable internal battery for it to normalize again. If I then connected to dock, the same would happen after some time. I've updated Thunderbolt software, drivers, firmware and also Thunderbolt 3 dock firmware and drivers, so no more to do there. I have not verified it completely yet, but it might be that the disconnect/crazy_stuff happens when the battery charge of the X1 reaches 100%. I once connected the X1 to the dock when the charge was 97% and it was stable then (the X1 does not charge on AC when the battery is > 95%). If this is the reason, one solution might then be to use Lenovo Vantage to set max charge to e.g. 97%, but I think this is a poor solution. Some ... Read more

Just setting up my new X1C6 with Win10 and the ThinkPad Thunderbolt 3 dock. Everything seems to be working, but occasionally the fan starts spinning like crazy, and a process named "WMI Provider Host" appears in the Task Manager with >25% CPU usage. After a few minutes the system is back to normal.  After a bit of Googling, I went to Event Viewer -> Applications and ... -> Microsoft -> Windows -> WMI Activity, and I found a series of errors that coincided with the excessive CPU load events. Every error has a reference to a process ID that corresponds to "Thunderbolt.exe". This leads me to think that the problem is related to my docking station. I tried downloading the docking station drivers from https://pcsupport.lenovo.com/en/solutions/acc100356 but it turns out that I have an even newer version installed already (something .12 vs .10) . Yesterday, I heard some loud hissing from the corner of the laptop where the TB3 ports are. It disappeared when I unplugged the dock, and came back after I plugged it in again. After a restart, it went away, and the port as well as the dock seems to be working fine (currently with Ethernet and a VGA monitor). Any ideas what to do here?

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

Hey Everyone, Hope someone here can help out.We've deployed ~60 of the 6th Gen X1 Carbon's (20KG Model Type) with the Lenovo Thunderbolt Dock (40AC Type)We've used Lenovo System Update to install all system and dock updates.When we've docked the computer the thunderbolt dialogue appears and we select always connect.Everything works for our users for about a day, then they complain that their computer isn't charging, their screens have gone black or are flashing, or the computer starts making device disconnect/reconnect sounds while the thunderbolt icon flashes in the taskbar repeatedly. All symptems persist after a reboot. We've been working around this by going into the BIOs and disabling the built in battery, Then plugging into the dock and powering on the computer from there. So far we've only had 1 user experience a recurrence (We haven't ruled out user error)I'd like to know if there is fix, beyond the "disable internal battery" solution. Thank you in advance for any insight you can offer.

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).

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?

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 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.
