LenovoThinkPad Thunderbolt 4 Workstation Dock

I’m using this dock with a Legion 7i Gen6 (11800H w/ 3070). Be aware, I bought this dock knowing full well it is NOT officially supported by Lenovo. I had read on several forums that it would work if you modified the power cable by removing a small piece of plastic that prevents the cable from fully seating inside the laptop power port. Bingo. Worked like a charm. Laptop is charging through the docking station.One other problem people mentioned that was the gsync wouldn’t work over the TB dock. I’m happy to mention this fully works and is supported. Currently using on a 1440p monitor with GSYNC enabled. One note, remember to disable hybrid mode before heading over to the nvidia control panel to verify gsync. Gsync won’t work with the intel GPU enabled.Only small issue I can see is the battery does begin to drain even while connected to the dock if you are planning to do long gaming sessions. My laptop was at 100% and after 2+ hours of gaming I was down to 80%. Just means the power supply can’t quite keep up with the demand so the battery helps supplement power.Other than that, all seems to be working. I have 2x 1440p monitors connected, multiple peripherals, a USB3 hub, and etc. Everything seems to be working. Didn’t have to install any drivers either, plug and play!Will update this review if I come across any issues. Good luck!

The product itself is excellent and functions as intended. Unfortunately, it was not suitable for my specific needs, leading me to return it and opt for an alternative solution. That said, if you're in the market for a docking station, I would highly recommend this one due to its quality and performance.

My laptop is a 2024 Lenovo Legion Pro 7i with a 4080. Monitor is a Dell 1440p 32" 144hz display. This dock was connected to the laptop via an Intel certified Cable Matters TB4 cable (though the TB4 port). All of the Lenovo dock drivers were installed.The Lenovo dock was intended to replace a TobenOne UDS035 dock which wasn't passing power through the TB4 port. Unless noted, the TobenOne dock didn't display any of the other symptoms noted below.- The external monitor (plugged into this dock via HDMI) was getting intermittent patchy blurred areas and strange artifacts. Particularly when gaming.- When changing between the laptop camera and the external Logitech USB camera, the display would momentarily flash off?- My Logitch wireless gaming mouse plugged into a new powered 7 port Anker USB hub hung off the dock (via USB 3.0) started stuttering. I also tried connecting the hub through USB C and saw the same results.- Power connector on the included Lenovo combo power/TB4 cord cord wouldn't seat. It almost looks like the connector has heat shrink going too far up the male connector, physically blocking it from seating. According to other reviews and a couple forums, some brave users are having luck trimming this plastic off. I didn't try.- The TB4 connector on the above Lenovo combo cable barely seated in the laptop as it's physically a very large/long rectangle and it impacted with the triangular corner of the side 7 Pro fan ducting. I believe this problem is only applicable to the 7 Pro (4080/4090) models of the laptop.- The TB4 portion of the connector was so large it was pulling down on the TB4 port. This alone ruled it out for me.- The "official" Lenovo dock tool software application said no firmware update was required. Other users reported v3 of the latest firmware resolving similar issues to what I was seeing.- The standalone Lenovo firmware update tool was repeatedly failing, throwing a vague error. Searches on the error suggest it's a common problem with no known solution that Lenovo has aware of at least since early 2024. Some people claim to be able to still update via Linux. I tried running an Ubuntu Live image but couldn't find the Linux version of the firmware update.- No power was being passed through the TB4 cable from the dock to the laptop. This was also the case with the TobenOne UDS035 dock (and why I wanted to replace it).- The 300 watt power brick for the Lenovo dock is huge. Maybe 50% bigger than the OEM 330 watt laptop brick.Bottom line is this: Either there are compatability issues with my laptop, the firmware on the dock is out of date, I recieved a defective dock, or this dock is just junk. Whatever the case, I'd avoid this dock if you're running a Legion series laptop or wanting to power your laptop via TB4.If you're looking for an alternative, check out the TobenOne UDS035 dock listed above. It lacks some of the rear 3.2 ports, but is getting the same FPS gaming through it that I see directly connected via HDMI and/or just using the laptop's display.

I searched far and wide for a dock that can support 3 external monitors while also providing G-SYNC, and this dock is one of the few with that feature set.Unfortunately, while it works, it can be finicky to get it to work. Perhaps it's due to unstable Nvidia drivers, but I noticed an uptick in crashes since starting to use the dock. Additionally, waking my laptop from sleep with the dock connected takes much longer than usual for some reason, and half the time my monitors don't wake up and I have to disconnect and reconnect the dock to get it to work again.

I have a Lenovo ThinkPad P1 Gen 5 work laptop that I have tethered to my home office using this same model dock, but I wanted to create an outdoor working area, since my home office is in a windowless basement. I'm too lazy to disconnect everything move it every time I want to work outside in the fresh air, so I purchased a rolling desk and another dock (this one), so when I plug in the laptop, it doesn't know the difference from one location to the next. As the P1 Gen 5 has a high power requirement, and I knew this one already worked, I went the same route. The only negative is the cost, but this one is over $100 cheaper than the identical model direct from Lenovo. Very pleased.

This Dock is awesome and works fantastically. Now, if you use cheap crappy old faulty HDMI cables, or/and cheap crappy Thunderbolt cables, and do not know how to update firmware, then this dock will give you a hell of of time. It will cause monitors to flicker and turn off unexpecting. Now, on the contrary, if you use proper normal HDMI and Display Cables, including upgrading the firmware of the dock and use good quality known working USB-c and thunderbolt cable all will be well. Awesome Dock, love it. With that said I do have 25 years of IT experience.
