Q: T480 + Hybrid dock not charging

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

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 was browsing the HK website and check out the order configurations. I discovered I can choose a first drive and a second drive. I personally prefer a hybrid solution with OS installed in SSD. But on the website, there is only SSD option in second drive. So if I choose a HDD as the first drive and an SSD as the second where the OS will be loaded by default?

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 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 just received this new dock this week after trying 2 others. For the past few days after a few minutes the WUDFHost.exe will start taking 20-30% of the CPU, the fan revs up, and my mouse pointer disappears on the monitors. I can still use the mouse, drag windows, etc. Just can't see the pointer or it won't show until the mouse sets still for awhile. Killing this process solves the issue, but it comes back quickly. Issue seems to coincide with the network card usage. Working with Filezilla today seemed to trigger it, but usually web browsing will do it.  I have updated all drivers and the Dock firmware. However it still says I need the dock firmware update even though it installed (two reboots). Now it errors when trying the install again. Things I have tried.I have had as many as 8 Virtual network adapters show up. Uninstalled all and Disabled Hyper-V service. No change. Removed one monitor - No changeI have tried different monitors. No change (although HDMI seems better than DVI with adapter.)Moved all USB devices and network cable to the laptop, out of the dock. No change)I have reinstalled drivers.

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!

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

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.

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?

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?

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!

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?

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.

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?

I have a Lenovo T480 Laptop that I use for work. I do testing in vehicles sometimes and need to charge my laptop when I'm in there. The problem is that when I plug my laptop into an outlet(AC 110V 400W MAX) in a truck my laptop will begin charging for a moment, and then stop, and then start, and then stop, and eventually my computer will crash and restart itself. I have tried using a 140W Power Converter(Schumacher XI14) plugged into cigarette lighter but still the issue persists. When I plug it into a normal outlet everything works fine. I have tried on 3 different vehicles so I know it isn't specific to one. Is there a special charger that I need to use in situations like this? Has anyone else ran into any similar issues? Any help would be appreicated. Thanks!

Hi jmyestre, and welcome to the Lenovo User Community!
 
One of these would do it:
https://www.lenovo.com/us/en/accessories-and-monitors/top-tech/65W-USB-C-DC-Travel-Adapter/p/40AK006...
 
It's not uncommon see problems with inverters and power supplies. You are stepping up from 12V DC to 110V AC then back down to 20V DC. This travel adapter goes direct from 12V DC to 20V DC.
 
Hope this helps!

Hi, I just bought AC Outlet Portable Charger RAVPower 27000mAh 85W (100W Max). The AC adapter of my ThinkPad T480 is rated at 65W max. So I think the power bank should be capable to charge my laptop.  I tested it to charge my Lenovo ThinkPad T480. The output is unstable. My laptop LCD keeps flickering because the battery keeps switching between charged and discharged. I tried to charge another laptop like ASUS A series and a PC monitor. And it works fine. Charging my Lenovo from house AC power sockets also works like normal. Could anyone give me advice on what is the problem with Lenovo? Any particular setting on my windows 10 or Lenovo BIOS  that I need to change? You could see my recording here https://drive.google.com/file/d/1mPBF4hO1tta-9SXwZEVSe3wK7jBzSxIR/view?usp=sharingAlso, the picture of my laptop AC adapter is here https://drive.google.com/file/d/1EFRpZJR36EmD4se92NHeIb8u_bFMkBeJ/view?usp=sharing Any help is appreciated.Thank you

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

We have recently purchased a couple of ProBook 430 G2s and HP Elite USB-C Docking Stations (HP part #: X7W54UT#ABA). The docking stations say they are supposed to charge the laptops but they don't. Any idea why they don't? Also, what docking station WILL provide extra ports AND charge the ProBook 430 G2? Thanks!

I have the following problems and have tried to get assistance from Lenovo without success.  My issues are:1)  Left USB will only work to charge Iphone or with thumb drive.  Left USB will not work with dock or Logitech wifi.  Right USB works 100%2)  When docked using smaller USB C port the screen will freeze on certain apps like act and quote works, but is OK with Microsoft outlook.3) Using Microsoft outlook screen goes black intermittantly.  Shut down outlook and restart and it is OK for a while.     I've updated all firmware for the dock (Anker), video drivers & USB port etc.    I thank you in advance for any assistance that can be provided.....

Just bought a Lenovo soga s730 (in other countries it can be called 730s) and Omen accelerator by hp, there are several problems, the first one: the dock connects only from the second time (the first time it detect the thunderbolt connection, but then driver just turns off, the second time everything is ok); Second: the video card appears in the device manager, but the driver does not automatically turn on, the reboot helps, then everything starts working. The last most annoying problem is that there is no charging through the thunderbolt connector, the dock is in SELF POWER status. Screenshots attached.
