ThinkPad X1 Extreme BIOS v1.19 FIXES ThinkPad Hybrid USB-C with USB-A Dock incompatibility

Q: ThinkPad X1 Extreme BIOS v1.19 FIXES ThinkPad Hybrid USB-C with USB-A Dock incompatibility

See subject. Ever since the BIOS upgrade, the dock no longer crashes. Two days running now with no problems; prior to the upgrade it would crash routinely when connecting via USB-C. I had to employ the unsavoury workaround of connecting the laptop to a charger and connecting it to the dock via the USB-A port using the USB-A to USB-C adaptor supplied. Now I'm connecting via USB-C cable only. In fact, I'd given up on using the dock at all and had it just sitting there. I decided to give it another go after reading that BIOS v1.19 fixed instances of BSODs occuring when connected to an external monitor (which I did experience now and again when connecting to an external monitor via HDMI i.e. not via dock). Dock Type : 40AFX1E Type : 20MF

Hi All I have an X1 Extreme which for the most part I love. However, I am getting seriously frustrated. For 8 hours a day I have the laptop connected via USB-C to a "Hybrid USB-C with USB-A Dock" via the supplied USB-C cable. In the dock, I have 2 x Benq 24" 1080p monitors connected via DP, a Cherry wireless keyboard/mouse dongle, and a Sennheiser headset for VoIP. The dock is connected to power using the supplier power brick and cable. A few times a day I will get a 'user-mode driver crash' where the dock and all the connected peripherals will crash. The laptop continues to function even though the lid is closed. If I open the lid, all is well on the laptop but the connected components remain 'frozen'. If I unplug the USB-C cable and reconnect it, everything comes back ok. I've tried removing the Cherry dongle and plugging it directly in to the laptop - same issue. Also done that with the Sennheiser. I'm using 1.00.13 of the driver for the dock, and it's on the latest firmware V10010 all from here The laptop works fine when it's not using the dock. It appears to freeze more often when I open a new tab in Chrome, or during a Microsoft Teams call, which seems to suggest it's a 'load' thing that is causing the driver to crash?  I've raised it with Lenovo and they sent me a new cable and closed the case. It's getting to the point where I'm wishing I'd stayed with my previous X1 Carbon. Any help appreciated!

Hi, Everyone. Got me a nice little x270 to replace my old x201.  Happy enough with the machine, but getting it connected to my accessories (monitor, keyb, mouse, ethernet) is a bit of a chore. This machine appears to have a "proper" dock port on the bottom.  Is there a compatible ultradock available for the model 20HN x270?  By proper - I mean, Not USB.  A nice dock I can simply drop the machine into when I'm at the home office.. Thanks!

Hello,I've got brand new T480 with ThinkPad Hybrid USB-C with USB-A Dock and I'm experiencing USB issues when docked.I have read related topics and they seems to be dead without any working solution. Description of problem:When I docked my T480 for the first time, all USBs (only mouse and keyboard) were working. I had left office for night and when I have returned and docked my laptop again, USBs seems to stop working. I?ve tried to reconnecting dock, powering dock off and unplugging devices or changing USB slots without any success.Only restart of computer seemed to get USBs working back again. BUT, there have been about 5 minute period when USB devices were randomly connecting and disconnecting without any warning.Problem appeared again when I left my desk for 30 minutes without turning off or putting laptop into sleep. USBs were dead again. Only restart helped and it was followed with 5 minute period of randomly disconnecting USB devices again.All other connected devices ? 1x FHD monitor via DP, 1x FHD monitor via HDMI and headphones via front 3.5mm jack are working without any problems and laptop is charging properly as well. My laptop is fully updated via Lenovo Vantage and dock in currently at only available FW. Is there any solution to this? It?s get pretty annoying for laptop that is meant to be docked! And it seems that problem occurs accros multiple ThinkPad Thunderbolt docks.. Thank you

I just obtained new LG 4K displays. I have them hooked up to a ThinkPad Hybrid USB-C with USB-A Dock via DisplayPort. The dock is connected to a T480s (20L7) via USB-C. I am running the monitors at 3840x2160 @ 60Hz. The performance is a bit laggy at times...it almost feels like I'm pushing the limits of what the laptop/dock can support. I have the latest drivers and firmware installed for both the laptop (via Lenovo's System Update utility) and dock. Even doing operations like Windows + TAB cause the WUDFHost.exe process (Windows Driver Foundation - User-mode Driver Framework Host Process) to spike up to 10% CPU / 100 % GPU.  Anyone else running with a similar setup? Any suggestions (short of getting new hardware) that I can do to boost the performance with my existing setup?

I have an X1 Extreme plugged into a Thunderbolt 3 Dock (40AN0230US).  Whenever the screen locks it cuts off audio.  I like this. Prevents sound coming from a computer that is locked.  However, when I unlock the computer, the only way to get the sound back it to restart the whole system.  This I don't like.I have 2 monitors (ThinkVision P27H's) plugged  in using Display Port and the audio is playing from one of the monitors.  The monitors are listed in the audio panel, but neither will provide any sound on unlock.  If I change the volume it lags terribly and eventually freezes.  I can switch to internal audio.I have:1) Reinstalled audio and display drivers on the computer.2) Reinstalled thunderbolt drivers on the computer3) Updated the dock's firmwareBut the problem persists.  Any ideas of what to try next besides getting a replacement?  Every item - even the cables - in the chain are supplied by Lenovo.  Should work flawlessly in my estimation.

Does the Thinkpad P51s support the Thinkpad Thunderbolt 3 Dock? I have the Thinkpad P51s with stock Windows 10 Pro and updated to latest drivers and Windows version and installed the latest Thinkpad Thunderbolt 3 Dock drivers. Attaching the Thunderbolt 3 Dock to the P51s as described in documentation, it charges the notebook, however, noting attached to the dock is recognized. I've tested with attaching USB flash drives, headphones, Ethernet, HDMI, and DP, but nothing is recognized nor are any warnings/errors displayed in Windows. While the Thinkpad Thunderbolt 3 Dock is listed as being compatible with the P51s and T570, the notebook order page does not list the Thunderbolt 3 Dock in any of the accessories lists. Lenovo Sales also confirmed that the Thunderbolt 3 Dock is fully compatible with the P51s.  However, I needed to purchase the Thunderbolt 3 Dock separately from the notebook order. What's going on? Has anybody successfully used the P51s or the T570 with the Thinkpad Thunderbolt 3 Dock? Or is this something I need to wait for full support via a future BIOS/driver update? Or perhaps my Thunderbolt 3 Dock is defective? Thanks,Boris

As far as I know, there are 3 ways of updating a ThinkPad:1. System Update Utility2. Lenovo Service Bridge Automatic Driver Scan3. Manual Driver Download & Install When updating my machine via System Update Utility, I was met with a BIOS update for 1.23:     Yet after multiple attempts, System Update Utility failed to download the BIOS update:  So I tried option 2, and used Lenovo Service Bridge to automatically scan and download the pending BIOS update. But oddly enough LSB returned by stating my machine was in no need of an update:   My third and last option was to manually download and install BIOS 1.23. Even weirder this time, I was met with a 404 Not Found page when downloading the update:   So what's the deal? Is this an isolated issue, or is this a Lenovo-wide servicing problem? Perhaps Lenovo pulled this BIOS update to work out some bugs with that particular version? I recently installed a 2nd SSD just to run Linux, but not until this BIOS issue is resolved.  Any insight would be appreciated.Thank you.

Please do not power off".  It stayed like this for 30 minutes and I finally decided to attempt power off but it would not respond.  Holding the power button for as long as 60 seconds does nothing.  I tried closing laptop lid...

I then ran Lenovo's System Update utility to get the latest video drivers.  Under the optional tab in the Lenovo update utility, I selected the "Optimus" drivers and hit download/install.  It installed, and I had to restart.4) Booted into Windows again, ran Lenovo update utility again, and again it had a video driver to install when I checked for updates.  I installed that, had to restart again.5) Booted into windows, checked screen resolution and saw that no external monitors were showing.6) I then decided to get a driver straight from the source.  Downloaded: the following file from  Nvidia: 334.95-quadro-notebook-win8-win7-64bit-international-whql.exe.  I ran the installation, it did a "Clean" installation with everything checked off.

Hi, I'm using a Thinkpad Pro dock with an L470 on Windows 10(both brand new). I have a VGA monitor and a DVI monitor connected, and I can output to both screens as well as the laptop display just fine, however as soon as I undock, or switch off the laptop, when I come to use it again, neither of the screens are showing as connected. I have to unplug them from the dock and plug them back in again, at which point they are recognised and work fine... until next time I have to undock/switch off. I have tried this with a different laptop (also L470, but running windows 8.1) with even worse results. On 8.1 the screen will repeatedly flicker for about 10 seconds, and any combination of the screens will work (sometimes just the laptop screen, sometimes just 1 monitor, sometimes all 3). Even when all 3 work, it rarely has the correct resolution, and takes several attempts to get it working properly. The whole point of having a dock is that there is no need to keep plugging things in every time you sit down, if I have to re-plug the monitors every time it is pretty pointless having a dock in the first place. I have updated the BIOS on the laptop, updated every driver, updated the firmware for the dock and Windows 10 is bang up to date. I'm about out of ideas now and was wondering if anyone had any ideas on a fix for this? I see web searches that this is quite a common issue, but most of the "fixes" are what I have already done, or are specific to Windows 7 or 8... Read more

Although I've read a lot of posts about various docks I am still a little consfused about which one to choose. It seems like the following ones would all work with the X1 Extreme:1. Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W:https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...2. ThinkPad Thunderbolt 3 Workstation Dock (170W):https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...3. ThinkPad Thunderbolt 3 Workstation Dock (230W):https://www.lenovo.com/ca/en/accessories-and-monitors/top-tech/Thunderbolt-WS-230W-dock-US/p/40AN023... Please correct me if I am wrong but to me it seems as if the only difference between these docks is that the workstation ones come with two AC adapters each and a special Thunderbolt/Power cable to avoid using two different cables. Or are there any other technical differences? So if I am okay with a two cable solution couldn't I just use the Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W and connect it via Thunderbolt while at the same time use my 135W AC adapter to charge the laptop? Thanks a lot in advance.

Hello, I've bought yesterday a Thinkpad Pro Dock (40AH0135EU) for my Thinkpad X1 6th Gen (Type 20KH).When i dock my laptop, the battery is charging and the external power button is working.The usb ports on the back do not work, the ethernet and displayport are not tested yet.Closing the lock does not fix this problem. Is anyone know i'f i'm doing something wrong, or something i need to do first?Thanks in advance,
