Lenovo USA ThinkPad Thunderbolt 3 Workstation USB Dock with 230w and 65w AC Included with Power Cords (MFG P/N ; 40AN0230US)

Old Unit Couldn’t Sync Monitors, New One Works!
I’ve always had a laptop dock at my desk. It just makes connecting the laptop so much easier rather than having to plug in and disconnect multiple cables when going portable. My new Thinkpad Carbon X1 Extreme Gen 2 uses Thunderbolt instead of a proprietary dock, so I picked up this unit.Yet so far it seems to handle everything I need. I have two monitors connected, Ethernet, audio cable, and all the USB connectors filled, including one going to a filled 10 port USB3 hub.I don’t have any USB3 storage connected, as I use a NAS and second drive in the machine. I only occasionally temporarily connect thumb-drives or external drives directly to the laptop, so I don’t know how well it would handle storage through the dock.The big annoyance I have with this dock is that it has trouble syncing two monitors. With my old proprietary docks it was instantaneously synced. With a fresh boot of the computer this dock will first display on one screen, then switch to the second, then switch back to the first, then back to the second, etc., etc. in an eternal loop. To fix it I turn off the second screen, wait for the first to stabilize, and then switch on the second screen and it works fine. This loop doesn’t happen if I always use the on/off button on the dock. As long as I use that button to put it to sleep and wake it up the dock only does a single cycle of syncing the monitors and it’s fast enough that it’s not crazy annoying. So, one star off because dual monitors are not as smooth as proprietary docks.**** UPDATE 01/27/2020They came out with new firmware for the dock in January 2020. After installing it I could no longer run multiple monitors at all, as all screens would turn black whenever the second monitor was plugged in. I had to hard shutdown the laptop to get a screen back. Prior to the firmware update the hub had trouble syncing, but eventually worked. Now, nothing. Every screen black. Tried all kinds of things including different monitors and cables, etc. I now have to plug one monitor directly into the laptop.**** UPDATE 02/11/202Contacted Lenovo support. They over-nighted me a new unit. This new one works. For the first time it boots up with two monitors connected without any sync issues. So, either the first one was bad or they fixed something over the past 6 months.

Not good for displays – basically an over-priced, underperforming USB hub
I have had this docking station for a year and have found it to be frustrating from day one. My set up is 100% Lenovo: Thinkpad X1 Extreme with GeForce 1050 Ti + 2x P27h-10 monitors. I figured that getting a Lenovo doc would mean it would be seamless. Hardly the case. It’s only been problems. I would not recommend this product.I should have known from day 1 to just return it. When you plug it in with the monitors attached, you get a “Display Connection Might be Limited” warning from Windows. Great. To try and solve this I have updated the dock firmware, updated my Thunderbolt drivers, updated my display divers, and finally reinstalled windows from scratch. Nothing fixed it.During normal use, the monitors will randomly just go blank. Sometimes I’m lucky and they come back after ~3-5 seconds, but often I have to unplug/plug the docking station. Doing that has about an 80% success rate, otherwise I have to restart the computer 🙁 A hassle if you are doing something with lots of windows open (I’m a developer so often have lots of terminals/compilations and other uninterruptible processes going).Additionally, sound is extremely unreliable. I use a monitor sound port (the only one one the doc is on the front of it and I don’t want the wire running across my desk) and frequently when the computer either wakes up from sleep or the monitors turn on after being off the sound does not work. I have about 80% success with going into device manager, and disable/enable the HD Audio device. If that doesn’t work – restart required :(In the end, I’ve bypassed the doc and plug one of my monitors directly to the thunderbolt port (no “Connection Might be Limited” when I do that) and daisy-chain the monitors using display port. The doc is now a really crappy (as in very few ports with a really short cable) USB hub that I paid hundreds of dollars for.
