T480 and Lenovo Thunderbolt Graphics Dock?

Q: T480 and Lenovo Thunderbolt Graphics Dock?

I own a Thinkpad T480 (20L5: Intel UHD graphics, Core i5 8th gen) and since it supports Thunderbolt 3, I want to attach an external GPU and display for light gaming. I see that Lenovo itself has a "Lenovo Thunderbolt Graphics Dock" but does not offer that as compatible with the Thinkpad series. Nevertheless, as Thunderbolt 3 is a standard, I am wondering if the Graphics Dock works with the T480. Did anybody already try that?

All, Can you use the T480 with the Lenovo Thunderbolt 3 Graphics Dock that has the external GPU.Look for the solution to attach 3 external 2560 x 1440 monitors (DisplayPort and/or HDMI) at 60 Hz. Also would the 40AJ0135US Ultra Dock allow me to use the 2 x DP and 1 HDMI at the same time. Thanks

We are currently using Lenovo T480 laptops with ThinkPad Thunderbolt 3 Docks (Model 40AC0135US) in our office and frequently encounter the following issues: ? When a user connects their T480 to the dock, their monitors do not display any video? When a user connects their T480 to their dock, their monitors will display video, but USB peripherals (keyboard, mouse) do not work? When disconnecting from a dock, the charging light on the T480 stays lit and Windows shows the laptop is still connected to power and charging? External displays flicker intermittently When a user experience issues with their dock, the only way to get things working again is to shut down the computer, disable the internal battery in the BIOS, and then plug the T480 into the dock and turn it on. However, the issue eventually returns and we have to repeat the steps again. We have also tried the following steps, but continue to see issues:? Run Lenovo System Update and install all driver, bios, and dock firmware updates? Replaced Thunderbolt cable? Change the Thunderbolt Security Level in bios to No Security and Uninstall Thunderbolt Software Most of our laptops are running Windows 10 1709. Has anyone else experienced these issues and know of a good solution?

Hi, I was wondering if anyone have any experience with the Lenovo Thunderbolt 3 Graphics Dock and if it works with the X1 Gen6 Carbon?  I did see it's been optimized for the IdeaPad 720S 13-inch 8th Gen Intel processor but would like to know if it works with other models too. It would be a weird limitation to lock it down to only one computer.. Thanks!

Out of ideas does anybody know of a trick or sequence of steps to get instalation completed ? Let me mention that the laptop is pretty current in drivers.

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 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...

I am using a T480 with the TB3 dock and 2 external monitors.My problem is my screens go black for a couple of seconds every x amount of time. I've updatad all drivers found under the Display and Video graphics section Drivers T480I remember when updating to Intel Thunderbolt Software for Windows 10 (64-bit) - ThinkPad T480, T480s, X1 Carbon Gen 6 - 1.41.565.0I received the following screen:(I did get 2 Thunderbolt SW apps in my start menu and uninstalled the one which was visible via add/remove programs) These updates did not resolve my monitor issue.I later on noticed there is a new TB3 Dock FWWhen I wanted to make the update I got the message the TB SW had to be above 17.4.77.400. (the version insalled and active was 1.41.565.0) I reinstalled TB SW 17.4.78.500 and performed the TB3 dock FW upgrade. Now I am in the situation I do not have a Thunderbolt SW application to allow/select TB devices to connect.V1.41.565.0 seems to be a new DCH driver. reverting back to the legacy driver 17.4.78.500 is not somethig I should have done.It seems the DCH driver came with it's own Thunderbolt SW application, which is no longer available. Is there a procedure to completly reinstall the DCH driver including the Thunderbold SW or revert back to the legacy driver with Thunderbold SW (which now states the application is not in use anymore) Thanks!

Hello, My company recently purchased a dual 4k setup for a work station. The setup is the following:2 ThinkVision P27 monitorsLenovo ThinkPad Thunderbolt 3 DockT570 (Type: 20HA) I setup the monitors and docking station yesterday and was able to power the displays using a X1 Carbon 5th gen (i5 model type: 20HQ) thru USB-C without issue. I have a user testing out the desk now with a T570. I'm able to get one monitor to funtion at 4K and the other is running at 1080p. If you check display settings I'm unable to increase the resolution to 4K. I've updated all drivers on the T570 including the display driver and thunderbolt docking station driver this morning and the system still fails to power dual 4K. I brought back the X1 I used previously and it powers the screens normally. I checked the specs of the T570 and its identical to the X1 as far as processor is concerned and the model page claims the USB-C port on the T570 can power dual 4K. What else can I try?

In short: can you recommend a graphics dock suitable for the Yoga X1 2nd gen? I just got this decked out ThinkPad Yoga X1 (second generation) and all it really needs to crush graphics-demanding games is an external graphics card. I've read articles about using Thunderbolt 3 graphics docks for just this use case, and I've read about a specific Lenovo Thunderbolt 3 graphics doc which appears to be only compatible with one model (not mine). What I can't find is anything about plugging one of these into my computer, or if it supports such a thing at all... Can any computer with Thunderbolt 3 use generic Thunderbolt 3 external, self-powered graphics cards?

(For those of you who have followed my previous threads, I've now ordered a T580 with 4k display). I'm looking for a T3 dock which can do the following on a T580. It would allow me to use just one cable to dock/undock it: 1) Attach a screen with a 2560x1440 resolution with 60Hz (digital connection)2) Attach a screen with a 1920x1200 resolution with 60Hz (digital or VGA connection)3) Full Ethernet port4) Charge the laptop (originally, it comes with a 45W power adaptor)5) Have at least 1 classic USB 3.0 port Unfortunately my budget is limited so that I can't go for the original Lenovo one. If there's a dock which can all the above except for attaching two screens, then this would be ok as well, for the time being (assuming I can run one screen via the dock, and the other screen directly from the HDMI of the T580). Then it would just be 2 cables for docking/undocking...

I have recently purchased both of the subject items.  I was informed via chat channels with Lenovo that the graphics dock would work with the X1 Yoga 3rd Gen.  However, upon connection, my Yoga recognizes that a Thunderbolt device has been connected but it does not recognize that a graphics card or USB ports exist.  Thus, my mouse, keyboard, and monitor do not work while connected to graphics dock.  I have downloaded and installed the drivers for the graphics dock but the result is still the same.  Does the graphics dock really work with the X1 Yoga 3rd Gen?  If so, is there a BIOS setting I must address to make this configuration work?

I used the Lenovo System Update (v5.07.0074) and was prompted to download and install (was listed as Critical Update) the Firmware to my Dock.  As always, I closed all applications and sat as the Firmware downloaded. I got the expected prompt to ensure I was plugged in. I then watched as the upgraded prompted me to install. Installation completed and everything appeared to be fine.  I powered down the thinkpad and disconnected. Worked from the living room, then went back to the dock. Connected, and noticed that before I connected the White light on the power button was illuminated. Shrugged, and pushed the power button. Nothing. I un-plugged the Dock, got a cup of coffee, returned and plugged it back in. Nothing. I then noticed that none of the pass-through power was working on the dock.  So, I unplugged it again.  Unplugged everything connected to it, and held the power button down for 15 seconds in an effort. All of this at the recommendation of Lenovo Support. Who, by the way, was very nice and well spoken. Nothing we did worked. I happened to have another Thunderbolt 3 cable in my bag, and no change. I powered up my new X1 Yoga, and connected the cable. No power. This wasn't passing power at all.

I just got my P52 with Quadro P1000 GPU hooked up with my new 40AN0230EU docking and 3x 24" monitors. Two of my monitors is connected through Display Ports, and the last one is connected with HDMI cable in the docking side and DVI in the monitor side of the cable. My problem is that the two monitors connected trough DP can do up to 1920 x 1200 pixles (which is recommended), but the last screen (which is identical to the other two) connected through the HDMI "hybrid" cable is only able to do 1920x1080! When I try to connect the HDMI directly into the computer instead of the docking I am suddenly able to do full resolution on the last screen too (1920 x 1200). I'm wondering what I can do to fix this? I've also tried to connect my P51 with Quadro M2200 GPU to the same docking, and that computer is able to do 1920x1200 on all the three screens trough the docking without any problems.

I recently received a ThinkPad T480s for my work PC and a Thunderbolt 3 Dock. I'm loving the laptop, but the dock is having some troubles. I'm worried either the dock is bad or worse, the laptop's Thunderbolt hardware is bad. The dock will cut out and appear to crash on certain occasions. I'm still trying to experiment with the triggers. I'm not 100% sure, but it appears that while I'm using it everything works fine - so long as I keep the laptop awake. It's when the ThinkPad goes to sleep or I leave my desk for a long enough time that the screens will have appeared to drop out. Or after the laptop has gone to sleep and I wake it up, then a few minutes later the dock crashes. For the most part the issue resolves itself once the dock power cycles and the displays come back up, but the last time this happened the screen was frozen and I had to do a hard shutdown of the laptop by holding the power button. My dock is pretty heavily loaded. It has the following peripherals attached: 2 DVI monitors with DVI to DisplayPort converterr connected to the dock1 VGA monitorEthernet connectionKeyboard USBMouse USBAudio OutAll monitors plus the docking powersupply are connected to the same powerstrip. The closest post resembling my issue is this one: https://forums.lenovo.com/t5/Displays-Options-and-Accessories/Thunderbolt-3-Dock-crashes-and-emits-c... But it doesn't appear to have been fully solved. I've updated the ThinkPad's Thunderbolt drivers and firm...

Hi guys, This morning System Update ran and installed a bunch of the newest March 2019 updates. The big one was the Intel Management Engine. After rebooting, when my Thunderbolt 3 Dock is plugged into my Lenovo P52 it freezes on the POST screen with the Lenovo logo. If i unplug the dock it boots fine, plug the dock in after the OS is booted, things work fine. Its just during the POST during secure boot. I tried reflashing the Thunderbolt firmware to the 11/2018 to no avail, reflashed the dock with version 3.x of the firmware (latest) no difference, downgraded the firmware on the dock, changed the boot support methods for thunderbolt, so on and so forth.  Its strange it doesn't get past the logo screen it just sits. Is there another version of the Thunderbolt firmware i should be using besides the November 2018? I really would not like to peel back all the different updates that it updatedAnybody got any ideas? Is there a way to find what the cause is? Honestly i can unplug the dock when i reboot and plug it back in within a second after the POST screen and things work as normal. Its just a pain.

Hello everyone, I recently bought a Thinkpad X1 Extreme and I am now locking for a suitable Thunderbolt 3 dock. 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.

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.

My t480 no longer charges via thunderbolt dock.

It will maintain charge. When plugging a docking station, attached perepherper function normally, but again, not charging. This behavior started recently.  Additionally I noticed that in device manager the UCSI USB connector manager sometimes will error out with an error 43. But this is sporadic and may be unrelated. Device manger view appears to repeatedly refresh, but have not been able to discover the conflict. I refreshed the os (win10) and it worked correctly for a bit, but then started doing the same thing again. Is this an error induced by a recent Lenovo or Microsoft update? Hardware problem?  Software?

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

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

Hello,I've just bought T480 with Thunderbolt 3 Lenovo USB-C hybrid dock and my laptop is not charing when connected to dock. External monitor and other devices connected to dock work fine, but laptop even do not recognize dock as charger. It acts like it running completely of battery. Where can be a problem? Thank you

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
