LenovoThinkpad Thunderbolt 3 Docking Station (40AC0135US)

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

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.

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.

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.

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.
