u/rugbrod1 Hi, We truly understand how frustrating it can be to deal with technical issues, and we want you to know that we are here to support you every step of the way. When you first received the dock, were there any recent changes made before this issue arose? Has it worked well for you in the past? Additionally, have you noticed if the problem occurs with any cables you use to connect the monitors and the dock? It's really important to ensure that all relevant drivers and firmware are up to date, including the BIOS, Intel Thunderbolt driver, Intel Thunderbolt firmware, Intel/AMD video drivers, Intel ME firmware, and dock firmware. You can easily find updates on the Lenovo support website: https://lnv.gy/3OqVWKZ . Keeping these updated often resolves many display and connectivity issues. If you're experiencing problems after a dock firmware update, such as no external display or USB devices not functioning, please download and run the recommended dock firmware executable from Lenovo's support page. For AMD systems, you may need to disable the built-in battery in the BIOS before reconnecting the dock and restarting your system. Also, it’s a good idea to check your display settings in Windows, ensure that all cables are securely connected, and use only original Lenovo adapters and cables. Please verify that your external monitors are set to their recommended resolutions. We’re here for you, so please keep us updated on your progress. -Kate_Lenovo More on reddit.com

Docking station works great as well - these Lenovo docking stations will attach to anything with a USB-C port, so I was able to connect a Dell computer, a Lenovo and a Microsoft Surface up, and each one worked just fine. Didn't think that was possible. Verified purchase: YesCondition: Pre-OwnedSold by: garwig_87 ... This is a very good docking station for my new Thinkpad carbon x1 but it does cost too much.

HALLELUJA Brothers and Sisters, there is a new firmware for the USB-C Gen2 40AS dock and it seems to be working just fine for a while now using the following firmware/driver combination:
Firmware: https://download.lenovo.com/consumer/options/thinkpad_usb-c_dock_gen2_fw_v1.0.8.03231.exe
Radeon Driver: https://download.lenovo.com/pccbbs/mobiles/r1bap05w.exe
If you have any issues, dont even consider going to their support forum, i've seen chimps on reddit with more observable intelligence than most ""support specialists"" there.
And not like anybody cares, but as of today i'm done with this sub.
All the shitposting is bloody annoying if you ask me and simply has nothing to do on a technology focused sub in my opinion. 70+% of the posts have zero information, 25% cant use search and as much as the rest of the 5% of this sub is amazing with mods/howto's and tonnes of good info and a just a handful of people who are actually know their shit... but i just cant be assed to shift through the shite for a speck of gold. Never thought i would say this but this sub could do with a moderator or two.
Good luck peeps and have fun!

r/Lenovo on Reddit: 40AS USB-C Docks suddenly stopped supporting external displays
February 11, 2026 -
I have two identical Lenovo 40AS Gen 2 docking stations. Yesterday, seemingly out of nowhere, they stopped supporting external displays. I tried three different monitors - two from Dell and one from Lenovo. None of them work with either one of the docking stations. All three work when directly plugged into one of two Lenovo laptops. I also tried various original USB-C cords to no avail. When I try updating the firmware through Lenovo vantage or directly it failed because of the DP hub.
Has anyone else experienced this issue? Does anyone have a solution or a concept of a solution? Thanks a ton for your input in advance! This is really torpedoing our families working from home situation.

Hey rugbrod1, I'm having a similar issue. DP hub fails in the firmware update, the rest go through and are good, but still my externals don't work. I followed all the resources Lenovo was able to provide via their website and the vantage app, still nothing. Did you have any luck? If so, would you mind sharing some wisdom with me? I'm a flight sim guy, trying to do external displays for my flights, but I cant even get to the part of setting them up in the sim because this basic part of just having external displays isnt working.
