    Two years ago I bought a used Pro dock for twice the price of this one. It serves me well and will continue to be used to give me docking capability in another location. This item is a steal of a price. If you have a compatible ThinkPad, this is a must have tool.Edit Update: After updating system device drivers via “lenovo vantage” I had both USB2 and 2USBv3 ports die. One USBv3 port still worked. Fix is: Device Manager > Universal Serial Bus Controllers > USB Root Hub (USB 3.0) right click Disable and then Enable returns USB port ops. Doesn’t take much time but a definite gut punch from lenovo.

    I’ve been a Thinkpad user for decades. There are certain aspects of the brand that just work for me. The dull black plastic looks good after years, the clunky look is durable and timeless, the keyboards are almost always very pleasant and easy to type on, even on an airplane, and these docks. This dock looks very similar to the one I had 15 years ago for my IBM built thinkpad.I’m using this with my pair of T440 laptops, cheap old laptops that have excellent keyboards and are a steal to buy refurbished. though it’s not listed in the compatibility list, it works flawlessly. The laptop slides very easily onto the dock, even with the extended life battery, and pops off very smoothly, without a click or any real mechanical noise. It’s a nice improvement over the older docks.You get tons of USB ports, an HDMI port, a few other video ports. Truthfully the T440 isn’t powerful enough to support a bunch of screens anyway, but you could run a pair if you wanted, and there are much more powerful laptops compatible with the dock. For the low price of this product, you get a really convenient way to connect a desk of accessories, and the T440 didn’t have a normal HDMI port anyway.If this is compatible with your Thinkpad, it’s a really good bargain and I found no defect with the way the laptop docks (some reviews for some docks complain about design flaws, but this model doesn’t seem to have them.

    I’ve bought several of these for laptops in the office – these have extra video ports which are needed if you want to run 3 monitors simultaneously (note: the digital video ports are paired up so you have to use every-other port on the back. The VGA is independent). My only advice is to make sure these are compatible with your laptop – pull up your laptop on Lenovo’s website, go to the accessories page, and see what docks they are willing to sell you. If this is in that list you should be good to go!

    I bought this docking station to pair with my recently purchased ThinkPad T460. This docking station makes it so easy for me to just set my computer on it at night and have it automatically back up to my hard drive. Plenty of ports available on the back, all of which work properly. This docking station includes a 90 watt power adapter, which is much faster than the standard one included with the ThinkPad. The dock also has a lock on it, which is a useful feature to stop the most basic of thieves, seeing as they could just simply unplug the station and walk away with it, but i’m pretty sure it’s intended for if the station were screwed down to the desk. It is super easy to dock and un-dock, and this feels like a very solid product, definitely an OEM product as well. If you have a ThinkPad of similar model and need a docking station, you can never go wrong with a Lenovo OEM product.

    Pro:1. Extra ports2. Easy docking3. No issues with dual monitor (2 Display port). Can extend desktop 1 & 2 just fine. Laptop can be a 3rd screen, but i usually just go with the two monitors.4. USB ports work fine. Even multiple usb keyboard/mouse dongles, recognizes more than one keyboard & mouse if you have them.5. Mic port works fine also for head set. (trrs)Neutral:6. Had some compatibility issue with a KVM switch, it may be the kvm / driver. It didn’t recognize the keyboard and mouse from KVM.con:1. none for now.Had it for a few months, so far so good, no issues.

    I purchased a used-like new option from the seller Abe’s Electronics Center. I was a bit nervous that the product might not be in great shape with being used but wanted to save some money. This option was about half the price of a new one. Well, it paid off! The one I received was packaged like a brand new one. It included the key for locking the dock and a power cable. Everything was brand new. Based on what I can tell, the only reason that it was marked as used was due to a few scratches that are barely visible which probably occurred during manufacturing. Everything else indicates that this was probably never used. I just wanted to put that out there in case anyone else is considering a used option to save some money. It was worth it!In regards to the dock itself. The dock works great! I wanted to use two monitors in addition to my Thinkpad T460 but the laptop only has one HDMI outlet. The doc has one HDMI and two Display Port outlets. I didn’t have any Display Port cables but ordered some that came quick. They are a great option and provide amazing resolution to my two 27 inch monitors. It also has an option for an Ethernet cable which is really nice if you want to get better speed while docked. I use this computer for work and the dock has not affected the speed or functionality of my computer. My laptop clicks right into place seamlessly making it really easy to use. It also comes with a key to lock the dock so that you don’t accidentally undock it. I don’t think that you would be likely to undock it accidentally since the release button is out of the way but it’s nice to have the added security/peace of mind. Another added bonus is that it keeps constant power to the laptop and my laptop stays charging. So when I need to move somewhere else, it is fully charged up.Unfortunately, I was only able to use this for about three weeks before my work decided to upgrade my laptop to an HP. Even though it was only three weeks that I got to use it, I would recommend this to anyone that has a Thinkpad. It’s really a game changer in my opinion!If you are looking to add a few monitors, simplify your setup, or minimize the amount of cables you have to unplug when moving your laptop, I highly recommend this!

    I really bought this to support the extra (3rd) monitor. I have a T440p with Intel HD Graphics 4600 and saw that this docking station can support 2 external 4k monitors in addition to the laptop screen. It was a bit tricky to get set up because the Display Settings under Control Panel (Win10) would not recognize the 3rd monitor. I had to go into the Intel HD Graphics Control Panel under the Multiple Displays page to enable the 3rd one. Once that was done I could access all 3 monitors through the Control Panel.There were a couple of posts on the internet about not being able to use both display ports at the same time so I am using one display port connection and one HDMI connection. (Never tested using both display ports so I can’t say for sure).The displays are a bit slower but it is only a laptop and it is driving a heck of a lot of pixels. The refresh rate is only 29p Hz for the 4k monitors which might not be good enough for gaming but is fine for office work.

    I have a T440p (which doesn’t even show up as a supported model in the list) and have been using my laptop open, connected to a 27″ monitor for years now. I recently came into possession of 2 identical 24″ monitors and was contemplating how to get these all set up. I knew of docks (use them at work), but I thought that they were going to be too expensive for me. I was a little shocked when these things popped up at less than $30! Anyway, I went ahead and made the purchase, and got a few cables to see if I could get all three monitors running at once. I went with one VGA, one displayPort-to-DVI, and one HDMI. Plugged everything in, and it all fired up just like that. It was actually harder to figure out how to get three monitors on my desk than to set them all up in the dock. Baring any issues down the road, this is a must own.

    Bought this for a T540p and it fits/works fine. One complaint would be that Lenovo seems to make one model of dock for 250 models of computers, so the exact fit of the T540p on this is a bit goofy. Case in point: there is a push tab on the back right side of the dock that simply rests on the battery, meaning the back of the computer doesn’t get a solid “weld” against the dock and moreso just sits awkwardly atop this button thing.

    tl;dr: • multimonitor works on Linux • 75-85% off makes it a hell of a deal • Lenovo cheaped out on the AC adapter, but it’s fineI picked this thing up because it’s compatible with my personal laptop, which despite having a Thunderbolt port, doesn’t support my existing TB3 docks. (I think this is for want of PCI-E bandwidth; my TB docks are dual 4k but the laptop’s TB3 lane is only 2x.)My first complaint about this thing is that it didn’t actually come with a slim-tip AC adapter. Instead, it came with the old barrel-type and a very short adapter cable. That adapter cable caused problems for me, but I only noticed the problem after I had dropped and stepped on it, so that may not be Lenovo’s fault at all. The problem is that due to slight tweaks or a will o’ the wisp, the power would get cut to the device, and when it powercycled, my monitors didn’t come back. I picked up a very cheap, third-party, aftermarket slim tip adapter with decent reviews, and I’ve had no problems of that kind since.LIMITATIONS:For multi-monitor use, the bandwidth limitations on the two DisplayPort ports on the dock allow only 3840×2160@30Hz each. This can be troublesome if your monitors use more bandwidth than that. Both monitors I have hooked up are that way: one is 3840×2160@60Hz and the other is 2560x1440p@165Hz. This means that with both plugged into the dock, sometimes only one will show up or give any output, but this can be worked around. Additionally, each DisplayPort port is paired with another video port of a different type, and only one of each pair can be used together. So it supports only two monitors. I have had no success daisy-chaining standalone MST hubs to try to add a third monitor, but I have only tried with one so far.LINUX QUIRKSYou will need a recent Linux kernel for this to work. I’m running Linux 5.3 on NixOS.Additionally, sometimes a monitor will not show up in the KDE graphical display management tools, even though it is visible in the output of `xrandr -q`. Even when the graphical display is broken, however, VTs pretty much always work. So I have gotten my monitors to behave by instructing xrandr to set the resolutions and refresh rates from the virtual terminal, then quickly switching back. My shell is Fish, so the command in my specific case is this:sleep 10s; xrandr –output DP2-1 –mode 2560×1440 -r 60; xrandr –output DP2-2 -m 2560×1440 -r 60and then switching back to the VT of the display server.OTHER NOTES:The laptop runs really hot most of the time when it’s closed and pushing as many pixels as it can on the two external monitors.
