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

Works well from laptop to duel monitors!

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.

So every evening, seemingly at random, all of the wired clients on my network would be unreachable. After hours and hours of testing different aspects of my network, replacing a couple of small switches and even ordering a completely new router I figured out this dock was causing a broadcast storm, making all the wired clients on my network inaccessible.It got to the point where I ordered a new router and right before opening it and swapping out my current router, it dawned on me that this wired network outage happened every night at about the same amount of time after I stopped working. Basically, when the laptop connected to this dock would go into sleep mode, the dock created a broadcast storm. The second that I unplugged the Cat5 cable from this dock, all my wired clients were instantly accessible again.Lenovo support refuses to admit or recognize that this is a problem. All drivers and BIOS are up to date. Using a manually set IP seemed to fix the problem for a brief period but it happened again today. The second I removed the network cable....BOOM....wired network clients are back up. I've found threads on Lenovo support about other users experiencing this issue also.Complete garbage and really sours me on Lenovo. Seems like the only fix is to take a loss on this and buy a different dock.

I have a Linux desktop that's a bit old, but works well. I got a refurbished Lenovo L13 Yoga laptop which is newer and faster, and came with Windows 10, upgraded to 11. I immediately put in a 2TB internal SSD, installed Linux but kept Windows on half the drive. I wanted to use this laptop as my main system, connected to my existing monitor, and I have a logitech keyboard/mouse that can switch between 3 systems, so I can use it for the old desktop, and the laptop with both Linux and Windows easily.So... after a short time, I decided that getting a dock would make this all much nicer, and it did. I've been able to reduce cable clutter, have more USB 3 ports, and a wired network connection that doesn't interfere with the USB-C port (Don't know who designed the connectors on my laptop, but they don't both fit at the same time).Got the refurb model of this dock, connected it up with no directions (there were none) and everything worked right off, with no extra drivers or settings. The audio works just like connecting a line out - all automatic. Even the on/off switch works to turn the laptop on and off. I believe it does not charge when off, which will keep it from overcharging. I'd imagine you could get around this if you needed to charge it while off.As a bonus, it charges faster than the charger that came with my refurbished Thinkpad, which was not the original Lenovo charger.By the way, I connected the speakers together with the desktop by using a simple Y-connector for the audio outputs.

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.

Prior to receiving this my WFH setup consisted of two monitors, several USB charging cables, a conference speaker, and the power cable to my laptop. Moving from my office desk to another part of the house involved unplugging everything from my laptop and then plug it all back in when I came back. Not that it was difficult or cumbersome, just a delay in my schedule and a slight annoyance. After receiving this, plugging all of my devices into it, and then connecting my laptop, it was great! Everything works perfectly and now when I need to take my laptop somewhere else I just disconnect the power cable to my laptop and off I go! When I return, I plug the power cable back in and my monitors and everything else are connected. It allowed me to shift cables around as well and clean up my workspace too. Before, I would periodically kick a monitor cable with my feet. Now, all cables are tied up and out of the way because they no longer needed to plug into my laptop and I could choose where I set the docking station on the desk. I should have purchased this a long time ago.

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.

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 :(

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 CableThinkPad Workstation Dock Slim Tip Y CableThese 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.
