Lenovo Thinkpad Thunderbolt 3 Docking Station (40AC0135US)

I am using this with a Lenovo Yoga 920 and Ubuntu 18.04. It works flawlessly. Display outputs, USB hub, offline charging USB port, Ethernet, power pass-through, and audio all work for me in the current Linux kernel with no special drivers or other hoops to jump through. Everything also runs at full 40Gbps speed as far as I can tell. Mine came with a 0.5M passive type-3 cable, which is the longest a passive TB3 cable can be and still support full 40Gbps connectivity. (not that this dock has 40Gbps of devices, but there is a Thunderbolt pass-through port, remember, so a downstream device like a graphics card could theoretically use that. I have not tried to do this.) Unlike the Dell TB16 and some others, this cable is type-c at both ends, meaning you could replace it with a longer cable if you wanted. Options are a longer passive cable limited to 20Gbps or a much more expensive cable with active electronics that allows you to get 40Gbps at a longer cable length. I think it's nice to have this option as the 0.5M cable constrains placement of the dock/laptop slightly on my desk. I plan to use a longer active cable once it arrives. The only thing to watch out for is that Ubuntu 18.04 supports Thunderbolt security directly through the default Gnome desktop environment. If you're using Unity, an older Gnome, or something else, you might not have any way to unlock access to the dock's functions other than the display adapters until you log in under the newer Gnome and authorize the dock's connection. Even after you've saved it for automatic authorization, you still have to go to Gnome every time to let it connect. You only have to do this once per boot/connection of the dock, and it continues to work under other desktops if you log out and switch over. If the displays are working for you but nothing else is, this may be your problem. Yoga 920 has no TB3 security at the BIOS level, but others such as the 720 do, so that's another thing to keep in mind. These issues is not specific to this dock, it's a general TB3 and Ubuntu thing. Hopefully someone will come up with a standalone tool for managing TB3 security in Linux soon, as Gnome hasn't quite made it back to the grown-up leagues yet and it's annoying to have to use it for anything. Just for comparison, and of relevance to those looking for a TB3 dock to use under Linux: Previously, I had been trying to use a Dell TB16 dock, expecting better support for Linux since Dell does officially support Linux. The problem is that they only support it in combination with certain Precision and Inspiron models. You need a firmware update to the dock just to get it working properly in Linux, and the tool that does the update checks the machine you're running it on and will only run on those models and in Windows. Some Linux support. I did eventually get it working, but it was a lot of hassle and it required using one of those Precision machines. It wouldn't even run on another Dell Inspiron that had TB3 type-c port on it but wasn't on the official support list. This Lenovo dock, by comparison, worked pretty much out of the box. I did let it run driver updates in Windows, but I'm not sure that mattered. I have a Yoga 920, which is not on the official support list for this dock (the 720 is) so if there was a firmware update that touched the dock and not the computer, you *might* need a Lenovo to run it, but I will say that it wasn't obvious to me that Lenovo was restricting support in that way, and it never said it was updating the dock, as opposed to the TB3 firmware on the laptop itself. This dock behaved as expected the first time I plugged it in under Linux. Last comment: Ubuntu 18.04 does boot more slowly when it boots with this plugged in. I don't hide the startup messages and what it sits at is indeed the loading up of thunderbolt. This only adds about 5 seconds or so, and it seems to work just as well if you plug the dock in after the boot is complete.

Ordered this docking station hoping it would would with my laptop (non-lenovo), but mostly got it so my wife could bring her computer home to work. Plugged everything in, and got nothing on the external monitors I had set up. I even dumbed the system down to only plug in power to the docking station, the thunderbolt usb, and ONE external monitor...to no avail. TRIED to get in touch with lenovo support to see what was going on, and apparently there's a known issue with these docking stations that it won't recognize external monitors. I waited a full day for a response from lenovo, which only turned out to be a "please send the part number and serial number of your docking station and computer"... after i sent them that information, there was radio silence. NO MORE responses between support. Let me also state that I tried calling them as well, was put on hold for 40 minutes, then they hung up on me. After I sent them my response with part number and serial number, I finally got another response another day later, saying to update the drivers, and they provided a link to their website with the downloads. I downloaded the drivers...while the computer can be charged via the docking station, the dock was still not sending signal to the external monitors. I don't know how what else I need to do to get this lenovo computer to work with a lenovo docking station. I can't get any help from support and I am still getting no help from support. I will be sending the unit back this week for a refund and looking for other options that will allow her "compatible" computer, as well as my "older" gaming laptop to work with external monitors. Lenovo is garbage. They should be embarrassed by there customer support. I'm embarrassed for them

I’ve been using this Lenovo dock at my desk for a couple weeks now, and it’s honestly made my setup so much cleaner and easier. Plug in one cable and boom... my monitors, keyboard, mouse, and charger are all connected without me fumbling around with cords every morning. The build feels solid too, not cheap or plasticy like a few other docks I’ve tried in the past. Performance has been smooth with no random disconnects or lag on peripherals. It handles dual displays with no issue, and charging through the dock works perfekt with my Thinkpad. Only thing I wish is that I had bought it sooner instead of messing with dongles and extra adapters so this just keeps everything tidy and stress-free. Total win in my book. Comes with a thunderbolt cable and power supply. You can't go wrong with this docking station.

My Lenovo Thinkpad X1 Carbon (6th gen, with 8th gen i7) works with the dock almost flawlessly with windows 10. My dock is hooked up with 3 x 24in external monitors, one on DP, one on HDMI, and one on VGA. Each monitor runs at 1080p, with my laptop closed. All other ports are fully utilized - ethernet cable, and the 4 USB ports - except the audio plug, which I haven't tried yet. The dock can run all day long without any heat issues. Now the caveats: 1. The DP cable can get disconnected from the socket if you move the dock around, or wiggle the cable. Make sure you plug the cable all in and don't move it (or the dock) around. 2. Make sure you run the Thunderbolt app from Lenovo to allow access to the USB hub on the dock in order for it to work. This is a one-time thing. 3. The supplied USB-C cable is kind of short (maybe 1.5 feet). I'm thinking of getting a longer one, like 3 feet, so that I have more flexibility moving my laptop around. Be sure you get the cable that can support 40 Gbps and adequate power delivery wattage (like 100W)

I regularly switch between a variety of thunderbolt docks, from the "dock" I use when I'm out and about, the dock I use at my office, and the docks I use when visiting the offices at HQ. The docks vary in brand from Lenovo, Belkin, and Dell. And of all of these docks, this Thinkpad dock is the only one that works universally for my Lenovo and Dell laptops without any muss or fuss, every time. I plug it in, the drivers are downloaded automatically through Windows, the screens turn on and the USB ports all work. The other docks will work well with one laptop or another, but fail miserably with others. The Dell docks for instance just straight up don't work at all with my Yoga 920. The dock's design is pleasing, with a little red LED for the dot on the 'i' in "Thinkpad" adorning an otherwise pleasant, sharp, professional look. Front port options are adequate, with another USB-C/Thunderbolt port for more modern accessories, and a 4-pole combination 3.5mm jack for your headset needs! I do have some complaints though: The power/sleep button on the dock does not work at all with my Lenovo Yoga 920 laptop. It doesn't do anything. I've actually not hooked up a laptop where the button does function. I've updated drivers etc, but no luck. Another quirk of the device is that it actually "pops" a little bit after it starts to heat up, much like you might hear metal start to make noise as it gets warmer. In the years that I've owned the dock it has never been an issue, but it does happen shortly after turning it on. Neither issue is enough to subtract a star though.

Worked and then a few days after the return period, it stopped working.

Bought this for use with my Lenovo ThinkPad P1 Gen 3 to run a dual 4K monitor setup at work. Runs both monitors at 4K 30 FPS decently well, although there is noticeable latency compared to directly connecting one monitor via HDMI. USB ports function normally and the laptop does charge, albeit slowly (and in some cases slowly loses charge while connected and under high load). Power button on the dock works as expected, as does USB charging of other devices. Occasionally, the dock loses connection for a couple seconds and reconnects afterwards - not sure why this is happening but it is not a huge issue for my application. For a "budget" dock used for productivity / web browsing it does the job decently, but I would never recommend this dock for gaming or other high-performance applications, at least with the laptop I am using.

I purchased this dock to extend peripheral capacity for my new Yoga 920 Lenovo laptop. I took a little gamble because I was unable to find definite answer to whether this dock works with Yoga 920, neither was appearing in compatible accessories on maker website. But since both Yoga and dock use Thunderbolt interface, I took a shot and got it. And I am happy to report all works perfect. Right upon dock connection, Yoga recognized it immediately and activate it. Now I was able to hookup additional external monitors: 32" 4K Samsung and 27" HD monitor. All work great simultaneously with Yoga running 4K at the same time. Then I added my external Pioneer USB3.0 BD/DVD burner to the dock and still have plenty USB ports to use going forward. The dock has everything you may think about including front headphones jack output , additional thunderbolt port and fast USB 3.0 port. Rear is equipped with two Display port outputs, 1 HDMI output, 5 USB 3.0 ports and even analog VGA15 output. The rear Thunderbolt output is used to hookup my Yoga using supplied cable. One more thing, the dock comes with its own power adapter. So my original Yoga adapter now stay in my travel bag while the laptop gets charged through dock whenever is hooked up with it. Overall great product, super easy to install if you have right laptop. Worth every penny.

I am using this Thunderbolt 3 dock with Lenovo X1 yoga Gen 2 and Macbook Pro 16 and it works great as of now. 65W Power delivery works for both platforms and all the ports are functional (not sure about ethernet yet) I had to update the dock to the latest firmware version which fixed glitched when connected to a monitor

Vendu comme produit reconditionné mais comme neuf et parfaitement fonctionnel, de plus le cordon d'origine US a été remplacé par le cordon secteur français, une petite mise à jour automatique du firmware par Lenovo Vantage et tout est OK.

I was very pleased with my purchase. The Thunderbolt 3 Dock worked as advertised. Initially I ran into some configuration issues in connecting my two external monitors to the docking station. It was my misunderstanding of the monitors input port selection. Everything worked once the correct input port was selected on the two monitors. Please note that the external monitors that I connected were not 4K; they were 1920 x 1200.

De momento no se si funciona, lo he comprado de segunda mano y no viene con el cable thunderbolt adecuado, ha traído uno que no puede enchufarse en ningún lado, como se puede ver en la fotos. El cable incrementa el precio unos 30€ y no contaba con este sobre coste, cuando llegue probaré como va.

The product should have had a warranty of 3 years.. I just bought it last year. When I had issue and went to lenovo.. they told me that warranty expired in 2021!! How on earth is this legal?
