Lenovo USA ThinkPad Thunderbolt 3 Dock Gen 2 135W (40AN0135US) Dual UHD 4K Display Capability, 2 HDMI, 2 DP, USB-C, USB 3.1, Black

I got this today and I'm in love. Everything is working seamlesly. I knew this was not listed to be fully compatible with my Lenovo Yoga C930, but I took the shot anyway since another reviewer mentioned the things that worked that did and didn't On my end, the only thing that I'm noticing that's not working is the power button. It has an amber light and doesn't do anything. However, I'm guessing this is due to the compatibility issue and there's not much that I can do about it. To be honest though? I couldn't care less about it. It finally allowed me to have everything connected in one place and only have one connection towards the laptop, so that I can easily move without issues. Moreover, I was having issues with the usb 2.0 in my laptop, and when I tried to connect my wireless mouse and keyboard to the cheaper USB C hubs I had there was too much lag. This dock solved the issue. The ethernet works perfectly, and so does everything else so far. So I would definitely recommend.

I have been a ThinkPad fan for decades and this Thunderbolt Dock is just amazing! Everything works and its brand new, even the smell. Everything came wrapped with manuals. Recommendation to download the firmware to take full advantage of every port. And make sure to check laptop compatibility. This dock may not work for every ThinkPad. Happily satisfied. Thank you! PD: my english is not that good sorry :(

Finally i decided to write something about the performance with macOS. Well, everyone knows this is a pretty tb3 dock, and i use it with my DELL 5290 2-in-1 (2* tb3 ports), everything works fine, power delivery, DP output 4K@60zh, HDMI output 4K@60hz, ethernet, extra tb3 port, all checked, it is a perfect dock if you want to a reliable TB3 connection. However, in my scenario i also want to use it with my macbook pro, 2017, 15inch. the fact is, i can't get the 4k@60hz from its own DP/HDMI ports, i have to use USB-C to DP/HDMI cable to connect it through the tb3 port at front panel, otherwise i have to run at 4k@30hz@HIDPI OR (QHD@60hz but without HIDPI). i have tried to intall the latest firmware through its website but no luck, it's really bad but we cant blame lenovo. anyway they designed it to support its own laptops (windows), the macOS support will never on its roadmap. but still a bit shame. Nov 2019, yesterday I updated the dock firmware to the latest 3164 version by a windows laptop, then switch back to macbook pro with macOS Catalina10.15.1, now I can get the 4k 60hz from the dock's dp. great work. the problem is, it looks the power supply of the dock are not sufficient for the macbook pro anymore. the battery of the macbook pro drained quickly after i connected the display to the dock's dp port. not sure if its firmware issue or i have too many payloads here. then i have to use the original power supply of the mbp to charge it. after did some research, i connected a secondary power adapter to its 230w port, now the dock is chargd by two power bricks and then it can charge the mbp again. all done now. now in Feb 2022, the dock died after 3 yrs, the battery indicator keep flashing when i connector laptop to the dock, changed with another windows laptop, same result, i wont purchase any Lenovo products anymore, so lame, revise the star to 1.

My original thinkpad docking station frizzed out. Without it, my office could not function. I paid a little extra for immediate delivery, but Amazon came through and delivered a new one withing an hour! It works perfectly.

My ThinkPad X1 Gen 7 laptop runs Linux (a Ubuntu derivative), but the manufacturer only guarantees compatibility with Windows, so I was a bit concerned if it would work well for me. However, it worked just fine. I didn't notice a single issue with regard to the dock station. Some overview of my experience: - The keyboard/mouse attached to the station will NOT work during the cold boot. They will fine work during a soft reboot though. - I use 2 monitors (HD + 2K). Tried them via HDMI and DP connectors, and all the modes worked well. I managed to get 1920x1080@144Hz via DP. 2K is constrained to 60hz. I guess you should not expect anything better at 4K. - I loved the dedicated headphones/mic jack on the station's front panel. It's very convenient. However, it's a separate audio device, so you can't just switch the head set, you also need to change settings in the apps. - One feature that this station has and it's not mentioned anywhere in the docs or amazon description is a power button. It's not the station's power button, it's a "relay" to the laptop's power button. By using it you can power on/off your laptop. Once, I managed to make my laptop sleeping via this button, but I have no idea how it happen. Alas, it's not documented. I'd suggest that some OS support is needed. If you're running Linux on ThinkPad X1 and want to use this station, make sure that: 1. You have the latest firmware. They did a lot of fixes for Linux compatibility. 2. The thunderbolt packages are installed and up to date. 3. The docking station is properly enrolled (see "boltctl" for Ubuntu). All in all the station is made very solid. Couple of "not so well" things that did NOT affect my review: 1. The station heats up a lot. It seems it consumes a significant amount of energy for own needs. 2. The docs are too brief. It's hard to figure how/if the USB ports are different. 3. The power button behavior is not covered in the docs at all. UPDATE (-1 star). When I received a new 4K monitor (BENQ), I figured that this dock port cannot handle 4K+2K setup. I wonder how it can handle 2x4K then. I've spent hours trying different cables and settings, and the conclusion is: two high-res monitors simply won't work via the station. The only working setup is attaching one of the monitors via the laptop's HDMI/USB-C port. It can be a Linux issue though. I haven't tested it on Windows.

I'm using this on a Lenovo ThinkPad T14 gen 1 and it works perfectly! I have it plugged into the thunderbolt port and able to use my two 32" 1440P monitors at native resolution!

I bought this for my Lenovo carbon Gen 2 extremely, but it also works with my work laptop (dell precision 5530).

Excelente producto, fácil de usar.

I loved everything about this product. Handles my UHD 4K Displays very well.

While the Lenovo 40AN0135US Thunderbolt 3 dock may work well, this product is listed as new and is clearly not. DO NOT BUY. The package came in a generic box and packed loosely and poorly. There are scratches on the unit itself, the documentation is missing, the included cable was the wrong type (USB 3.1 instead of Thunderbolt 3) and the power cable is clearly used and dirty. The package was also missing: ThinkPad Thunderbolt 3 Workstation Dock Split Cable ThinkPad Workstation Dock Slim Tip Y Cable These are listed as coming with the product by Lenovo when you buy new. The listing has them as included, but clearly they are not. DO NOT BUY.
