T480 + ThinkPad Hybrid USB-C with USB-A Dock USB problems

Q: T480 + ThinkPad Hybrid USB-C with USB-A Dock USB problems

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

Hi Guys,I have a T480 laptop with a pro dock docking station and 3 monitors i want to try to get working.2 of the monitors are working fine via a VGA > DP adapter. The 3rd i bought a USB-C to HDMI adapter, though i cannot get this to work, even with the other two monitors disconnected.If the laptops undocked and the 3rd monitor is connected to the USB-C port, it works. Has anyone had luck with 3 monitors on this docking station? I have been considering a display port hub, can we use adapters with these hubs ok or does it only work if the cable is solely DP Thanks guys

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 all Anyone else have a X1YG3 as well as a Hybrid USB-C with USB-A dock? It's this one which is being described: https://support.lenovo.com/au/en/solutions/pd500180 I have two of these docks, both connected to two external monitors, one via HDMI directly and the other with a DisplayPort to DVI adaptor. Unfortunately on only one of such docks, upon plugging the USB-C port in, the two monitors never power up, and in Device Manager, the error of USB Port Reset Failed shows up. The way to fix this is to use Device Manager to uninstall the Unknown USB Device (the dock) and then in a few minutes time it fixes itself up. Would anyone else have experienced something similar, or is this a replacement dock beckoning?  Thanks in advance!

Hi, I"m using a T480 with Windows Hello / face recognition, but it works very unreliable.And I am not referring to the quality of recognition, but the operation itself.After a reboot, I can see the IR LEDs blinking, so I know the camera is in operation and it works perfectly.after a while (Don't know what exactly is needed to reproduce, perhaps some sleep/hibernate cycles), the IR LEDs and the camera are simply not activated on the sign in screen. Fingerprint Auth works, however, there were some cases when fingerprint also refused to work in such cases. Inside windows, I have seen several times the Window Camera Frame server taking too much CPU and  I thought it might be related, so I disabled this service. It did not change anything - Face recognition still worked for some time, and then it stopped again. I suspect this could be some driver issue. Anyone else facing such problems? Any ideas, hints? Thanks

I've purchased the Lenovo 520 Yoga, and I need to have a docking station for it. The shop where I bought it recommended the Thinkpad USB-C Dock and said it was compatibale, but I can't get the laptop to recognize the dock.I've installed the drivers as instructed, and I've gone through the troubleshooting guide. I can't find anywhere that this laptop is compatible with the dock, so I want to ask if anyone else is using this combination. And if not, do you know of any other docking stations that are compatible with the 520? This is a problem, as my job requires me to use a docking station to work efficiently, and a lack of docking possibilites really makes the laptop worthless. Any tips, suggestions and experiences are useful! Best regards,Morten, Norway.

Hello, I have a P50 that I am trying to output to two displays. I have a Pro dock that I realize can only drive 1 digital signal with so I am using the DVI port to display to 1 external monitor and the LCD itself. I am trying to connect a second monitor using the mini DisplayPort  on the right side of the laptop, but Windows 10 does not detect this monitor to be available. If I disconnect the DVI cable on the back of the dock, I get output on the mini DisplayPort. Is this just a limitation of the laptop or do I have something configured incorrectly? I am able to achieve the desired functionality (DVI monitor from dock + mini DP monitor from laptop + LCD) on an X240 ThinkPad, but the setup does not work with a P50. Any help would be appreciated.

Hi guys, I have a ThinkPad T480 combined with a Pro dock (side). I was hoping to use 3 external monitors (not including the laptop screen). The pro dock only has 2 display ports and the laptop has a HDMI port which i was hoping to all use to get my 3 displays.My setup is 2 VGA external monitors to display port adapters and 1 hdmi monitor to the laptops hdmi port directly. 2 display port monitors display fine, however the HDMI display goes black. If i un dock the laptop, the HDMI monitor works.Can i not output all 3 at the same time, i know the laptops chipset allows 3 monitors.I was thinking of buying a USB C to HDMI adapter for the 3rd monitor, maybe this would resolve it? thanks in advance

I have a user with two LT3053s (2560 x 1600) and his previous T440 + Ultra Dock (I believe) supported the full resolution at 60 Hz (again I believe).  I upgraded him to a T480 and our standard Type-c dock that we deploy limited the screens to 1920x1080 @ 60Hz.  After this and complaints from the user of headaches from the drop in resolution we purchased a TB3 Gen 2 Dock and even after plugging the dock in to the actual TB3 port on the laptop (not the top type-c port) we are having issues with not all of his devices working, namely the kb+m. Any ideas here?  Right now we are running it with the 135W power adapter that it came with, but there is also another power adapter available that did not come with the unit we purchased.

I'm using a Razer Trinity mouse, and it works fine, as long as I plug it directly into the laptop's USB port. If I try to use any sort of USB hub or switch (I've tried three different hubs -- each with a different set of USB cables) the mouse cursor randomly freezes on screen for about one or two seconds at a time. I tried installing the Razer Synapse 3 software on the laptop, and turned off the mouse lighting (to reduce power usage and rule that out), but that didn't help. I've also: -updated all drivers/bios via System Update-installed all Windows Updates-tried all three Windows power profiles

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

I was able to get further with an E520 than the L380 and I think it has something to do with the docking station. I have followed the steps outlined in this post https://www.itecs.ncsu.edu/servicedesk/kb/enabling-pxe-boot-for-lenovo-thinkpad/ as well as various combinations of those listed settings.

I've seen this issue on two separate HP EliteBook 840 G1 laptops now, it's the same build, but different methods of installing Windows 10.The first was a straight 8.1 to 10 upgrade so there were a lot of variables to throw in there with preinstalled software/drivers and such. The second is a 100% fresh build.

I've tried to put it to sleep and wake it up, it does not work.  The only way to get the laptop screen to work is to do a complete shutdown by forcing the laptop's power off.  Once it's off I can power it back on and the laptop's display works properly.It works the same way the other way as well.If I have the laptop display on and then dock the laptop, the dual displays never display anything.  If I shut the lid without powering it down and put the laptop to sleep, the displays never turn on.  If I wake it up, the displays to not function.  Again the only solution to get the dual monitors to work once docked is to power the laptop down entirely and then turn the laptop back on.The laptop, dock and graphics are obviously not working...

I have a new T480 and Lenovo Thunderbolt 3 dock. I find that often when I close--but in no way shut down--the computer for the night, when I restart in the morning, it completely restarts, so I lose open tabs, unsaved work, etc. I can understand enough of the system event log to determine that the computer always goes to sleep when I close it, then, per the power plan, hibernates three hours later--or at least tries to. The first sign of trouble in the logs comes at the time of hibernation. For example, at 2:37:25 this morning there is the routine Information event, "The system is entering sleep. Sleep Reason: Hibernate from Sleep - Fixed Timeout." This is followed immediately by the warning, "6105 - deauth after EAPOL key exchange sequence". Over the next 5 minutes come two more warnings and eight errors. Then nothing until I start the machine in the morning. One of the first events on restart is the information message, "The last shutdown's success status was false. The last boot's success status was true." It appears to me that this only happens if the computer is plugged into the Thunderbolt 3 dock overnight. To the dock are connected a (gigabit) ethernet cable, a displayport monitor, a mouse, a keyboard, and a pair of headphones. Here is a fuller dump of the error log at the last time it was hibernating, or trying to: Level Date and Time Source Event ID Task CategoryError 7/30/2018 2:41:33 AM Microsoft-Windows-DistributedCOM 10010 None The server {3EB...

Dear all, having just updated my the firmware of my Ultra Dock (40AJ0135EU) via Lenovo Vantage to V5.0.6.1, there is now something truly wrong with the power supply; on startup, I am greeted by the famous "low wattage" screen and when using windows, the battery is slowly drained (Lenovo Vantage claims that a 25 W USB-C adapter would be connected instead of the 135 W one). The issue never occurred prior to the firmware update and consistently shows up for any other power cable (trying several ones, including 90 W). So while the "low wattage" screen is annoying, the more severe issue is the constantly drained battery which makes using the dock basically impossible over time. Any ideas? I did not find a way to undo the firmware update - or is the recommendation to wait and hope for yet-another firmware update that (may) solve the issue? Maybe someone has a similar issue and a better / working solution Thx!

I have two 27" 2560x1440 60hz monitors that are plugged into the new Pro side-connect dock (40AH) with a new T480 (Intel 620 integrated graphics) in Windows 10 Pro. I can get either monitor to work fine with the dock individually, but trying to run both simultaneously by extending or duplicating the desktop between them seems to fail as selecting either option under Display Settings just makes the primary monitor black out for a few seconds then come back - the secondary monitor stays black.  There's no error msg or popup that would help me investigate further unfortunately. I'm trying this with the T480's lid closed, and I'm running the latest 1.14 BIOS update and latest Intel HD graphics drivers. This setup worked fine on my old OneLink dock and X1 Carbon previously, so I don't think it's an issue with the monitors themselves. Anyone have a similar setup with the new Pro dock that's working?

In the next day when I wake my machine (by pressing the power button on the Gen2 dock) my system wakes up fine but my external keyboard doesn't work.I have to reboot my laptop to get the keyboard working again. Anyone have dealt with the same problem with Lenovos docks? All drivers and firmwares are installed from Lenovos site and the Thunderbolt3 software (the older app not the new UWP) sees the dock fine. Tried to unplug and plug back the USB keyboard but still it doesn't recognize or work.

Hello, We have a problem with 2 laptops (ThinkPad X270) that "freeze" on the LENOVO logo when using Lenovo Ultra Dock with monitor Dell UZ2715H.Display Dell is plugged by Display port ports and one USB 3.0 (9 pin - used for display integrated webcam) connected to ThinkPad dock.When notebook turned ON with connected USB 3.0, computer freeze on LENOVO logo (To interrupt normal startup, press Enter) and work only when USB 3.0 disconected, or turned OFF and again Turned ON. Firmware on Dock is 2.33.000 Any suggestion? 

A:Lenovo ThinkPad Ultra (Pro) Dock + ThinkPad X270 (20K6) + Dell UZ2715H

I am just going to guess that computer is trying to boot via USB, so you might try changing the boot order in the BIOS so that Windows Boot Manager or the HD is first.

I have a Thinkpad T430 type 23474W4 and a Thinkpad mini dock series 3 type 4338-15U. I already have a Lenovo LEN LS2223wC monitor hooked up to it through one of the DVI ports. I have a a Lenovo LT1952p Monitor that I would like to use as a second external monitor. Both monitors work individually through either DVI or VGA. However, I can't get them to both work at the same time no matter what configuration I use. I was told they didn't have to be identical monitors to work together. What am I doing wrong?

X1 Carbon 6th Gen - (Type 20KH, 20KG) Laptop (ThinkPad) on ThinkPad Pro Dock.  I have a secondary display (connected with DisplayPort).  When the battery is charging, the secondary display works properly.  As soon as the battery is fully charged (100%), the secondary display disconnects and goes black (no signal detected).  The power is still on the the display.  The only way to get the secondary display to reconnect is to unplug the power supply from the dock, then plug it in again.  Has anyone else experienced this?

When I dock the computer and press the power button on the dock it doesn't recognize my monitor as the main screen. I have to hit a key (Windows 10) and put in my password hoping that it's doing that and then the screen comes up. If I reboot after that ... THEN.... it recognizes my screen as the main monitor. How do I fix this? The only time this happens is when I use it off the dock and then put it back on. If it stays on the dock all the time it does just fine. Any fixes for this? Thanks...

Apologies if something similar has been posted, I just can't find the answer. We have a 5th Generation Thinkpad X1 Carbon connected to a Thinkpad Thunderbolt 3 dock. At the moment the display is mirrored using a VGA cable to connect to the dock. What we would like instead is to connect the dock to 2 external monitors with separate content on each monitor and the laptop display blank. I just can't figure out if this is possible, what might be needed, and how! Any help greatly appreciated.

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
