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

Apologies if something similar has been posted, I just can't find the answer. We have a 5th Generation Thinkpad X1 Carbon connected to a Thinkpad Thunderbolt 3 dock. At the moment the display is mirrored using a VGA cable to connect to the dock. What we would like instead is to connect the dock to 2 external monitors with separate content on each monitor and the laptop display blank. I just can't figure out if this is possible, what might be needed, and how! Any help greatly appreciated.

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

Sorry for the bit of a wall of text, I'm trying to be as detailed as I can. I've been pulling my hair out a bit on this one, and I've tried steps found in at least half a dozen threads that I read through on here, but to no avail. I wanted to make a separate thread because my issue seems to be happening before most of everyone else's. I've tried: installing drivers in a specific order, not plugging the dock in until everything is setup, forcing a PD reset (hold power 8 seconds), updating bios to latest and trying all the Thunderbolt security/compatibility/passthrough settings, etc.  Specifics: An end-user has a 6th gen X1 Carbon and purchased this dock: https://www.lenovo.com/us/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun... Which specifically says it's compatible, and I've used the dock finder utility to verify the compatibility. I'm running Windows 10 1809 and have triple checked driver versions and BIOS settings. The driver shows up correctly in Device Manager and the Thunderbolt software runs properly. I've disabled my antivirus in case something was interfering.  Problem: However, no matter what I try, when I plug the dock into the machine, I don't get a single prompt or anything that indicates it's been connected, other than that the LED on the dock goes from amber to white, the NIC lights up (if plugged in), and the laptop charges properly and indicates as such. You're suppo...

How can I add a wireless card to the Carbon X1?  The original answer was "can't be done" becuase the computer is a sealed case and has no capability for it.  I call BS!!  The computer obviously has a slot for it, a Sim card holder, and the option to order it from the factory with wireless.  How to add wireless to a non-wireless Carbon X1?

A:Docking Stations for X1 Carbon

You don't say which generation X1C you have, but AFAIK you can add a WWAN card.  Instructions are in the Hardware Maintenance Manual for your particular model.
 
The challenge will be antennas if they aren't already installed, and finding a card that passes the BIOS whitelist.
 
This isn't something I can address in detail, but if you'll list your MT-M - like 20FB002SUS as an example of a WWAN-upgradable unit - others will probably be able to help.  (Upgradable means that the antennas are already in place.)

Hi Lars,Warm Greetings & welcome to Lenovo Community, happy to have you here.
 
I doubt as in order to use Lenovo Thunderbolt 3 Dock there has to be Thunderbolt present in your older systems. It doesn't work with USB 3.0 ports.

Hi, I am looking for a laptop which is small in size (13 - 14 inches) and has strong specs. I locked on to Lenovo X1 Carbon 5th Gen with 512 SSD and 16 GB RAM. My specific requirement is to use 3 external displays via docking station, I look online and found this "http://lenovoquickpick.com/usa/system/thinkpad/x-series/x1-carbon-5th-gen#accessory/68848" and "http://lenovoquickpick.com/usa/accessory/40AC0135US/thinkpad-thunderbolt-3-dock-us". I thought I'd talk to Lenovo Support about this just to make sure. Even their support has two opinions. One agent said that the docking stations will work with 3 external displays (2 display ports and 1 VGA). I talk to another agent after a few minutes and he said the laptop will only work with 2 external displays and not 3. Can anybody from the community confirm which of the two agents are correct. I currently have HP 650 G2 Probook which works perfectly fine with 2 display ports and 1 VGA port at the same time and let me use 3 external displays. Thank you,

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.

A:Thinkpad Thunderbolt 3 docking station does not charge Thinkpad P51 battery.

Everbody's p51 would be the same.  The thunderbolt port won't work as a charging port.  The thunderbolt specs specify 100w max.  That's not enough.  Your thunderbolt port is not for charging.  To charge via the dock, you need a workstation dock, not a thunderbolt dock.  A thinderbolt dock can charge things like an x1 carbon (5th gen) or x1 yoga (2nd gen)

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.

I have a 5th gen Carbon connected to the Lenovo Thunderbolt docking station. After some time, perhaps a sleep or hibernation, the laptop loses ethernet connectivity and can only use wifi. ipconfig reports media disconnected. But if I do a restart of Windows 10, ethernet is back, no problems. Also if I use the ethernet dongle connected to the laptop's weird little ethernet port, there are no issues.  There are other issues with the dock, like intermittent loss of wireless keyboard and mouse connectivity, but I'll worry about those in another thread.

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

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.

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?

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? There's a separate thread discussing the 'hissing' which appears to be coil whine from the dock in my case. Another person resports more of a clicking sound from near the left of the laptop (near the TB3 port), see here: https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Carbon-6th-Gen-Coil-Whine-Dock-Issues/td-p...

Hello Everyone, I am new here so please go easy on me.I just bought and X1 Carbon 5th Gen laptop c/w Thunderbolt 3.0 docking station.The problem that I have is that the docking station won't recognise any of the external screens that are connected.I am using two Acer screens (one is connected using HDMI port on the dock and the other one uisng Display port).I have tried by connecting just one screen but nothing.I can see that Thunderbolt software is installed and its connected to my laptop.The laptop will charge through the docking station and also the wireless mouse and keyboard will work fine through the dock.Lenovo recommended that i should update my drivers.So I installed Lenovo Companion from Windows store. But it won't update my system. After clicking on System Update, I will get an error message saying "There is a problem in reteriving new updates for your system.Please try again later".Hence I downloaded all the drivers from support website and installed them manually but my docking station is still not working with the external monitors.The monitors works fine when connected directly to the laptop using the HDMI cable. Thanks in advance for your help.

Machine model: 20HRCT01WW At seemingly random intervals the Dock stops working (for USB perphirals) and my wife has to move keyboard/mouse to the machine itself - defeating the purpose of a very expensive dock. Machine is fully up to date the current version of windows and all drivers (including the Thunderbolt dock). I would report this directly to support but Lenovo it won't allow to me register my wife's X1 with my account inspite of the fact that I'm the one who ordered it. Ugh. ThanksMark Levison

I have a 6th Gen X1.  One of the thunderbolt ports no longer works with the monitors on the docking station - the keyboard and mouse do work.  The monitors do work when plugged into the other thunderbolt port.  I am worried that one will stop working too.   I do not know of any damage or issues and I ensured the latest drivers were installed.   Any ideas on how to troubleshoot?
