When turning on the Thunderbolt 3 workstation dock using a P52 the USB and audio ports do not work. Means that a USB connected keyboard or mouse is not usable. I can resolve the issue by unplug&plug-in the 65W power supply cable. Why are keyboard/mouse/headphones not instantly working when switching on the dock? Is there a special setting necessary? Thx!

Hi all, Before I blow $500 on this dock can anyone tell me if my t470s will work with it? I want to output 4k at 60hz to two monitors. https://www.alogic.co/alogic-thunderbolt-3-dual-display-docking-station-w-4k-power-delivery-black.ht... It uses HDMI for one of the outputs, and my monitors are thinkvision p27u-10's which have HDMI 2, so that shouldn't be a issue.

HiI just would like a description and confirmation on what the following options do under the Thunderbolt 3 dock in the Bios for this series laptop I tested the option "No security" and this seems to bypass the authentication pop up when logged into Windows when plugging in the Thunderbolt 3 dock. So essentially it enables network ethernet connection to work straight away Can someone tell me what the other options do?

I have a X1 6th Gen. Recently I got two different Thunderbolt 3 docks. Work gave me a Kensington one. I bought a Caldigit one for home. I have them connected via the diagrams below - basically through my monitors as usb Hubs. (nBoth docks have similar problems: 1. Keyboard repeats keys: https://tinyurl.com/TB3Keyboard2. Mouse randomly pauses: https://tinyurl.com/TB3Mouse3. Web cam stuters: https://tinyurl.com/TB3Webcam4. USB Head set crackles5. Sometimes my laptop hard freezes requiring a hard reboot. Yuck. There's even more USB devices (phone, etc) but they're more "optional" than than mouse/keyboard/webcam/headset.  When i connect them directly to the docks, there's no (maybe fewer?) problems.  Has this happened to anyone else? It feels like an X1 problem since this repros with two different monitors and two different docks. A few other coworkers have reported weird issues as well with their X1 and the docks.

I have an XPS 13 9360 connected to the WD15 dock. I've noticed that regularly the external mouse and keyboard I have attached to it stop working.
Here are some things I have observed:

When this happens, the mouse and keyboard are still recognized by the computer. i.e. when I plug and unplug them I can see them show up and disappear from Windows Device Manager. Also, when I view the mouse and keyboard's device status in Device Manager it reports "This device is working properly."
The USB port on the dock seems to be working fine. I know this because when this happens I can unplug the mouse and plug in a different peripheral (e.g. external hard drive) and find that it works fine. But when I replug the mouse, the mouse still does not work.
I know my mouse is fine, because when it stops working I can unplug it from the dock and plug it directly into the laptop's USB port which causes it to work fine (but if I unplug and replug to the dock it does not work).
The laptop's built-in keyboard and touch pad still work fine.
This usually seems to happen sometime after coming out of sleep especially when waking the computer using the power button on the dock (but not always as far as I can tell so far).
Sometimes restarting the computer fixes (temporarily) the issue.
Sometimes unplugging and replugging the dock fixes (temporarily) the issue.

A:When Using WD15 Dock External Mouse and Keyboard Stop Working Occasionally

This is admittedly a rather long shot, but try installing the latest Thunderbolt firmware for your XPS 13?  I know the WD15 is just regular USB-C and that the USB-C controller firmware is updated as part of the regular system BIOS update, but I'm wondering if the Thunderbolt controller might still be in the hardware path somehow and therefore a firmware update there might fix something like this.

Hi community,  I'm expiring strange issues on some of our X380 Yogas when working with a USB-C Dock (Type 40A0). The cursor starts to freeze for a second, and then jumps, sometimes the keyboard types unwanted letters (I don't know the english word for it, but e.g. I would like to type Thinkpad, and out comes Thinkpaaaaaaaaaaad or Thinnnnnnnnnnkpad), and on a connected USB Headset the audio quality is bad. This happens only with USB devices connected over a USB-C Dock, if directly attached to the Yoga its fine. Also the internal Keyboard and Trackpoint are working fine. There are not always all 3 problems the same time. And usually after a clean boot everything is OK, it happens only after undocking, and docking in again.  On some computers having that problem, installing the USB-C Dock Firmware update fixed it. But on some others it does not. Anyway installing this Update is a pain, since it cannot be installed unattended. Maybe any ideas here? I have not contacted Lenovo support yet about this. Regards, DJ

My company has issue me a Lenovo T470s and an Ultra Dock to replace my existing equipment. I have two external monitors connected to the docking station with display port cables. The problem that I am experiencing is that if the laptop is docked and the cover is open, I get video on the laptop display and one external monitor. The other external monitor gets no signal and goes to sleep. If I close the laptop cover, I get video on both external monitors. A co-worker told me that this was working as designed and that the solution for getting video on all three monitors was to connect one external monitor to one of the display ports and the other to the DVI port. (He hadn't tested this configuration and is using two display ports with the laptop cover closed.) I tried my coworker's suggestion and got the same result but prior to switching to DVI, I downloaded and installed the latest(?) driver for the HD Graphics 620 adapter from this website (lenovo.com) and that seemed to solve the problem (when using two display ports) but after shutting the laptop down, I had the same issue the next day. What I want, is to have the laptop cover open and still be able to use two external monitors and get optimal resolution on all three monitors. What's the best configuration for achieving this? (Don't guess, like my co-worker. Give me something you've tested and that you can confirm that it works.)

hi, I have setup one of my faculty with a Yoga 920131KB plus Thunderbolt 3 Dock. He has an existing monitor (Samsung Syncmaster P2450) that should support 1920x1080. Seems to be current on all drivers and patches under Win10 EDU version. (Including the CCG4 Firmware Update to v55). We are using the HDMI output from the dock. If we try to configure extended desktop to the Samsung monitor at 1920x1080, the screen extends off both sides about half an inch. Maybe also a quarter inch over at the top.  As a work-around, set at 1680x1050, video generally works as expected, but the display starts about 2" in from either side. Generally I don't like using add-on utilities (prefer to just use standard windows built-in options), but somewhere along the line this has the Intel Graphics HD Utility.  I was using that to switch resolution, the Windows settings seemed to track along with changes in the Intel utility, but still overscanned the display.  I played with some other settings in the utility about Display Scale (other than 100%), didn't seem to change anything. A second problem occurs with this setup: when the laptop is used at home, put to sleep, then plugged into the dock, the screen is displayed on the external monitor at maybe 200% (?).  That is, you only see the central portion of the image.  No fiddling with settings seems to correct it, but rebooting usually fixes it. The second problem also occurs with a similar Yoga 920 + Dock (d...

Also wanted to mention something I noticed while working on this: I saved a log from the Intel Utility. There is a section in there about "Maximum Image Size".

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.

Issue 1I purchased the ZBook Studio G3 + 2 months wait on the Thunderbolt 3 Dock to primarily connect 2 4K Samsung monitors.  When connected via the display port one will display at 4k while the other will only display @ 2560X1440.  I had bought a a couple of CableMatters thunderbolt 3 X display port adapters while waiting on the dock.  If I plug one of the monitors in using the adapter and the other into the display port both will display 4K.Anybody else having this issue? Issue 2After the computer goes to sleep only one monitor will wake up.  The NVDIA control panel still shows both connected.  Only way to get the second monitor awake is to shutdown and reboot. Issue 3I have the displays configured to go blank after 1 hour.  Once this occurs and I enter my password all of my open programs are displayed on one screen rather than on both.  This would be normal if you have undocked and re-docked a laptop. Issue 4If the laptop is opened while docked. One display goes blank and one is duplicated with the laptop screen.  This is not typical docked behavior.  I moved from an  Elitebook 8540W with dock.  I'm really questioning my whether this was an upgrade.

We received a new 5510 laptop that works great on its own, but when adding in the thunderbolt dock we experience odd issues

1. If the laptop lid is closed while connected to thunderbolt, the laptop will hang at the Dell bios screen.  If the lid is open while power turned on, the laptop boots up fine.  However, the BIOS screen is still not visible on the external monitors, only when the OS has loaded
2. Dell shipped a new dock which had no differnce, and then I uninstalled every single driver and downloaded/installed in order from Dell's website, including updated Thunderbolt firmware and BIOs

The laptop is running Windows 10 x64

2 things I have noticed:
1. In device manager, the Thunderbolt Controller 1575 is hidden.  Viewing hidden devices and opening this controller states:
"Currently, this hardware device is not connected to the computer (Code 45)"  The resources tab states that there is a problem with the device
Of course, reconnecting makes no difference.  I have also unplugged all peripherals from the dock to make sure there was not a conflict
Second, in device manager, there is no listing (visible or invisible) for  ASMedia USB 3.0 Extended Host Controller Driver for Dell Thunderbolt Dock, regardless of uninstalling it through Add/Remove Programs and re-installing.
One more note - I am able to work normally after booting with the lid open successfully and then closing the lid.

A:Precision 5510 issues with Thunderbolt dock

I have the exact same symptoms with the same hardware (precision 5510 & WD15). the computer will not POST when it is either started or restarted with the built-in display closed. If the lid is open... all is fine. Ohh.. and when you do try to start/restart with the lid closed, i get a 2 orange, 7 white blink code. it will continue to repeat this until I open the lid and press the power button. This will then cause the unit to successfully POST and boot up.

I have three ZBook 17 G3 that I cannot get a Thunderbolt dock installed correctly on. The first does not seem to want to install the thunderbolt driver, so that one's fun. The other two are having a different issue entirely. I have read multiple threads here about similar issues, and none have offered a solution for my situation.I have tried the latest BIOS, I have tried an older BIOS, I have downloaded the drivers and firmware(which won't install because it doesn't detect the dock) Whenever I plug the dock in, Windows installs the drevices, but gets stuck and winds up with a "Base System Device" that it cannot find a driver for. I have tried three different docks, and three different cables. All have the exact same result. Is there an obscure driver that I need to download to install that is not obvious in all of my searching? Any questions or clarifications, I'm happy to respond. -Keith

Hi all, I do tech support at a university that uses various Lenovo notebooks across campus. I have noticed a trend among the users that have a Thinkpad Yoga 370 Notebook and are using a Thinkpad Thunderbolt 3 Dock, myself included. Occasionally (every few weeks or so), one of the affected systems will show "plugged in, not charging" tooltip when hovering over the battery tray icon. When this happens, the charge indicator light by the charging port and Thunderbolt port does not turn on, the battery continues to drain, and unplugging the Thunderbolt cable and either plugging it (or the regular power cable) back into the notebook has no effect. These systems all use Lenovo System Update to keep their drivers and BIOS up to date, and I have updated the firmware on the Thunderbolt 3 Docks manually. This issue was brought to my attention because it started happening to me and my laptop/dock after the first few weeks of having it, and this behavior continued to happen for months. I would constantly be plugging in and unplugging my laptop, as I do on-site support in several buildings, and my laptop goes everywhere with me. In October I stopped using my dock entirely, and since then have had 0 problems when just using the laptop's regular charging cable. I have 3 or 4 other users whom I support that have this issue though; due to the sheer volume of documents they need open at once, they need a multi-monitor setup and ethernet ports, so not having a dock is not an option.

I just got a new Carbon X1 6th generation (20KG).  I started using this with my Thunderbolt 3 dock (40AC), that I successfully used with my previous Carbon X1 5th Generation. There seems to be some compatibility issues here. After using it with the docking a while (apprx. 1 hour), the X1 suddenly started to continuously disconnect/reconnect from the dock (each 2-3 seconds), before it permanently was disconnected from the docking and would not connect at all.  When I disconnected the X1 from the dock and restarted (without connecting to dock) the X1 Thunderbolt software and devices/drivers related to that on the X1 "went crazy" and appeared/disappeared from the device manager continuously (each 2-3 seconds). I needed to enter bios and temporarily disable internal battery for it to normalize again. If I then connected to dock, the same would happen after some time. I've updated Thunderbolt software, drivers, firmware and also Thunderbolt 3 dock firmware and drivers, so no more to do there. I have not verified it completely yet, but it might be that the disconnect/crazy_stuff happens when the battery charge of the X1 reaches 100%. I once connected the X1 to the dock when the charge was 97% and it was stable then (the X1 does not charge on AC when the battery is > 95%). If this is the reason, one solution might then be to use Lenovo Vantage to set max charge to e.g. 97%, but I think this is a poor solution. Some ... Read more

I am using a Jabra UC Voice 550 Duo USB headset (Skype model) with Windows 7, for business communication. Or, at least, that was the intent: The reality is that if I use any ports on the docking station, I lose connectivity in the middle of a call. Several Skype chats started out okay, and then the microphone on my end simply stopped working (I could still hear the other party.) Also playing audio (Youtube via Google Chrome) has also resulted in eventual loss of playback. I have had to plug the USB headset directly into the laptop, in order to obtain glitch-free audio (via the on-board Intel USB root hub). The ASMedia USB root hub in the Thunderbolt docking station seems to be the culprit: I have two HP Z24n monitors plugged in via DisplayPort, and it makes no difference if I use USB ports on the monitor vs. directly plugging the headset into the Thunderbolt docking station itself. Since the laptop has limited USB ports, I would like a solution to this problem, please. The ASMedia root hub is running on driver version 1.16.33.1, dated 04.02.2016. One last thing: I got driver software for my Z24n monitors on CD-ROM, but hardly any notebooks are shipped with CD/DVD drives these days - and I could not find an online copy of the software, so I could install the display profiles.

I've been experiencing general stability issues with the ThunderBolt 3 dock. I purchased Extreme X1 for work because of the impressive specs and portability of the device. Overall I've been very pleased with the performance and build quality of the device and Lenovo's software suite makes keeping everything up to date really easy. WIth that said, I've had LOTS of issues with general stability of this product. It appears to Lenovo had issues with the discrete graphics (Nvidia Geforce GTX 1050 ti) which may have mostly been resolved with the latest update. I'm on a fairly recent version of Windows 10 (1803). When using the Thunderbolt 3 dock I still experience lots of issues where the device freezes or becomes unresponsive when docking or undocking. Often times I must force power off the device completely because the device is unable to wake from sleep correctly when docked. I have not tested whether device itself is unable to wake from sleep or if it's just because it is connected from the Dock. However sometimes the device WILL wake correctly but then certain functions will not work, notable USB data will not work often but will be powered (keyboard lights are on but can't use caps lock, for example). Or sometimes the VIDEO won't display at all (thunder bolt graphics issue with discrete GPU) however I can clearly see caps lock works on my keyboard.

We purchased a new X1 Carbon 6th Gen with the new Thunderbolt 3 Dock Win 10 1803 and have had all kinds of problems. Bad enough to consider other brand alternatives. All Lenovo drivers are current, we updated the firmware and drivers for the dock. With that we still have the following problems and dont know how to resolve them1. The network connectivity from the dock to laptop with USB-C loses connectivity on occasion. Also when the user shuts off the laptop, comes back and turns the laptop on, no network connectivity is re-established. The only way to fix this is to unplug the USB-C cable and plug it back in. Sometimes that will lock up windows and we have to do a hard shut down and start of the laptop. 2. Running the display out from the dock is not always reliable. The monitor will turn off randomly. To bypass this issue we have to just plug the monitor directly into the laptop. 4. Occasional random bluescreens with a stop  code DRIVER_VERIFIER_DMA_VIOLATION. This error is related to bad drivers.Are we missing something. Is there anything we have to set in the BIOS to resolve these problems?

Also tried to reboot the computer multiple times.
Even tried a K17A Dock and had the same issue.
We were finally able to get the computer to connect to the vpn once we used a usb net adapter to plug the ethernet cable into.
Tried plugging the usb adapter into the computer directly and into the dock. It worked whether it was directly connected to the computer or the dock.
It only does not work when we connect the ethernet cable to into the lan port on the TB16 and K17A dock. And only for the one computer.

I have been experiencing issues with my USB keyboard on my XPS15 9550 w/TB16 Dock when the Logitech G610 USB keyboard is plugged into TB16 USB 2.0 port in the back.
The keyboard will hang, accepting no input. or may hang on a certain letter, thus producing an "aaaaaaaa" across the screen until the keyboard "comes back".
Keyboard seems to work fine while plugged directly into the XPS15 rather than the TB16.
I also have an external USB drive for backups that I use connected to the TB16, although seems to be functioning fine. I have not had a backup fail, so, I assume it is working fine.
I have tried downloading all of the drivers, and re-installing them in the proper order according to the documentation while disconnected from the TB16, and then connecting to the dock.

Is anyone else experiencing a similar issue?  Is it the dock or the 9550?

A:USB Keyboard Hangs/Quits working on XPS15 9550 and Thunderbolt Dock TB16 . W10Pro x64

If you happen to run Citrix Receiver, make sure you're running at least version 4.9, since earlier versions are known to cause USB issues with the TB16, although that typically presents as the USB ports not working at all.  If not, then there was also an issue with intermittent USB device disconnects that was eventually solved through a combination of drivers and firmware, so when you say you've downloaded all of the drivers, please confirm that includes:
- BIOS
- Thunderbolt firmware
- Thunderbolt software
- ASMedia USB Host Controller driver

Hi!I just got a new "X1 Carbon 5th Gen - Kabylake (Type 20HR, 20HQ)" and a "X1 Carbon Thunderbolt 3 Dock". I have an external screen connected to the dock and it works fine (VGA connection). I also have an other monitor with display (DP) connection that I want to use. But my computer can't find the other monitor, only the one with VGA connection. Is there any easy ways to fix this problem?Best regards

I have erratic mouse movement and keyboard issues from these external components when used through the dock via the USB ports. I have an E-Port Plus II dock.  If I leave the laptop slightly open the issues go away. 
The same issue that was reported here, but no resolution was posted. Is there a fix? en.community.dell.com/.../19997634

Hi Guys,
i installed the D3100 dock on my XPS 13 and everything works fine, until i had some kind of update on windows10. After this, windows shows the message "display link core software is not available anymore on your pc". I've updated the driver, re-installed the displaylink driver, but since that upgrade, the mouse and the keyboard started to lag in a pretty buggy way.
If i use the laptop without the dock everything works fine.
I'm using Dell wireless mouse+keypad.
Any suggestion?

I am not sure if this should be on here or on the peripherals section of the forum.
I own a XPS 13 laptop and type c dock, I have erratic mouse movement and keyboard issues from these external components when used through the dock via the USB ports.  If I leave the laptop slightly open the issues go away.  Also if I plug them directly into the USB ports on the laptop I also get no issues. This is my current work around although for a brand new laptop and dock having to plug in 3 things rather than just the docking station doesn't make much sense.
I have tried the keyboard and mouse on other PC's with no issues.

Hi everyone!I recently purchased a T480s with the following specs:- i7 8550u- MX150 Graphics- 16GB of RAM- WQHD Display I am running a Setup with the following Displays: internal Display @ WQHD, external Display 1 @ WQHD, external Display 2 @ FHD.Everything works perfectly fine, if I connect External Display 1 via a Thunderbolt Dock and DisplayPort and External Display 2 via HDMI directly. The problem I encounter is the following:I have some "small Adapters" for Thunderbolt -> HDMI or Display Port. They used to work fine until yesterday, now all adapters, except for one (USB C -> HDMI, USB and USB-C) have stopped working. All I get is a message stating that there is a malfunctioning USB device.Funny part: All adapters work fine on a Dell XPS15, Lenovo MIIX 510 Tab, and so on. Whats the problem? I already tried System Restore to a few days ago, did not help... Thanks,Jakob

Hey all, I'm having an issue with my new X1/Thunderbolt setup, and I was hoping I could find some help here. Problem:I'm currently having a problem where my keyboard and mouse are cutting out intermittently. This happens at random for about a second or so at a time.With the mouse it almost feels as if the computer is lagging.. but it's not. With the keyboard it can cut out mid press of a key, and the letter (or it's even happened to me while pasting) will just keep going for a second or two before the keyboard comes back in and sends the signal to release the key. Setup:I have a new X1 Carbon gen5. This is replacing a Macbook Air, which I had hooked up to an Apple Thunderbolt 27" monitor (Model# A1407):https://en.wikipedia.org/wiki/Apple_Thunderbolt_Display(These are both from ~2011) This is a Thunderbolt 1 monitor, so the connector is the same shape as mini-display port. Apple makes a Thunderbolt 2 -> 3 adaptor (2 was backwards compatible with 1), which I have and am using:https://www.apple.com/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter My keyboard and mouse are wireless logitech products, and are hooked up through the monitor. The display seems to work fine. I don't game really, so maybe I'd see some flickers if there were fast refreshes going on, but for my use so far I have not seen any issues. The only issue is the hooked up peripherals (which so far is just the keyboard and mouse).These all still work f... Read more

Hi,I just got a X1 Carbon 20HR, and the ThinkPad USB-C Dock with it. The issue is, that when I use the dock and have it connected to my external monitor [Samsung LU28E85] then the mouse is lagging a bit - but enough to annoy me and make it harder to reach the right buttons.... This is both when I use a cabled mouse, as well as via Bluetooth or the Logitech connector. I would say thoug, that the cabled mouse seems to perform a little better than the wireless connections.When not in the dock and working on the screen of the laptop, there are no issues with any of the mice at all.There also seem to be a bit of lack with the keyboard entries...... Any advice?I was wondering if it can be the dock which is "underpowered" and should have been the Thinkpad Thunderbolt 3 Dock instead? I have you can help Kind regardsLasse

Hi, I think I hit some sort of edge case here. I've tried a lot of things but just can't seem to nail down the problem. Hope you guys can help me out with this one This is the equipment I have:X1C6 - 20HK-CT01WW (Windows 10 pro)ThinkPad Hybrid USB-C with USB-A Dock - 40AFWired mouse (Logitech-G402 & Corsair Harpoon) The problemWhen I connect the mouse to the dock and the dock to the laptop, the mouse works but it always freezes randomly for a second and then moves normaly for another few seconds before getting stuck again. This is really frustrating me and have no idea what to do. Also I dont have anything else attached to the dock. What I've triedOk so to debug this, I replaced the laptop with my old laptop. So my setup now looks like this:    Mouse <-> Dock <-> Old LaptopThe mouse works with no problem at all. At this point I feel the problem is with my X1C6 since the setup works with an old laptop. So I download all the drivers and install them. Including BIOS update and chipset drivers on my X1C6. No luck at all. Same mouse freezing problem. I feel my mouse has some compatability issue so I try a different wired mouse from a different brand. Still no luck at all. I try a third mouse which is wireless. I plug in the USB receiver into the dock and windows installs drivers and wireless mouse works perfectly! I tried to connect the wired mouses directly to the X1C6 and it works perfectly! So no driver issues. T... Read more

Hello all. I have a user with an older X1 Carbon (Machine Type34443444GYU) and a ThinkPad USB 3.0 Dock (basic model from what I can see). They've been using it for over a year at the very least but for the last couple of weeks their wired keyboard and mouse on the dock just lock up. The keyboard and touch pad on the laptop work fine. Undocking and redocking do the trick but this happens several times a day with no rhyme or reason. I've run virus scans, hardware diags, done some cleaning on the system, updated all the drivers I can find and I even swapped the entire dock and all of it's cabling for the same model. We had a spare that had never been used. I reinstalled the dock drivers fresh. The only thing I have not had a chance to do is to update the chipset which I saw was availble via Lenovo updates. I intend to do that as soon as I can get access to the system again. If that fails to help does any one have any ideas at all about what to try? Thanks!

It appears that the only way to report a BIOS bug to Lenovo is to post in the Forum (at least that is what hardware support told me), so here goes! Base system:20HF-CT01WW (T470s)BIOS: 1.11 (issue also showed up under 1.10)Windows 10 Pro Edition, Creators Edition, fully patched.

The Thunderbolt port only shows up in Device Manager when the Thunderbolt firmware utility is run - it appears that Thunderbolt ports dynamically attach to the PCI bus only when necessary (i.e. firmware utility asks it to turn on or a device is plugged into the port).Booting with battery from a cold boot (machine powered off for at least 15 seconds) results in a hang with the windows boot time circle of dots cycling endlessly.

I have a X1 6th Gen. Recently I got two different Thunderbolt 3 docks. Work gave me a Kensington one. I bought a Caldigit one for home. I have them connected via the diagrams below - basically through my monitors as usb Hubs. (nBoth docks have similar problems: 1. Keyboard repeats keys: https://tinyurl.com/TB3Keyboard2. Mouse randomly pauses: https://tinyurl.com/TB3Mouse3. Web cam stuters: https://tinyurl.com/TB3Webcam4. USB Head set crackles5. Sometimes my laptop hard freezes requiring a hard reboot. Yuck. There's even more USB devices (phone, etc) but they're more "optional" than than mouse/keyboard/webcam/headset.  When i connect them directly to the docks, there's no (maybe fewer?) problems.  Has this happened to anyone else? It feels like an X1 problem since this repros with two different monitors and two different docks. A few other coworkers have reported weird issues as well with their X1 and the docks.

When we have a USB Mouse and or Keyboard plugged into the laptop or the ThinkPad Pro Dock (M3F00) it will not boot, it will boot however if we turn off the USB UEFI Bios Support off, then we will have to use the laptop keyboard to logged in. Then the external mouse and keyboard will start working after that.How do we get this to work with the external keyboard and mouse. Seems to be a hit and miss issue with our organization.Added note...Mcafee Endpoint Encryption is also installed, and the system will lock up either before or at the McAfee login screen. Machine Type Model: 20L6S0SJ00Operating SystemWindows 10 (64-bit)Processor: 1x Intel Core i7-8650U Processor(Core i7-8650U)Memory: 2x 16GBDDR42400Operating System: Windows 10 Pro 64(EN:English)Hard Drive: 1x 512PCIeNVMeOPALWireless Network: 1x Bluetooth Version 4.1Ports: 1x RJ-45Camera: 1xGraphics: 1x Intel UHD 620Monitor: 14.0 FHDIncluded Service: Sealed Battery Replacement

Hi All I have been crawling through these forums and Google in general, it seems a lot of people have similar issues. I run a T470s, I use a Startech USB-C to HDMI adaptor allowing me to connecto to 2 external monitors. I have done for many months and all was fine. I recently ran system update and found multiple drivers needed updating, I ran this and since I cannot use my external monitors.  Thunderbolt software is up to date, as per screenshot it doesnt show the controller version or details in lower half. Device Manager doesnt show the controller at all (even hidden devices). I have tried:uninstall/reinstall of TB SWrunning the firmware update tool but that just says 'No Active Controller' in the system.I have tried reinstalling every Intel driver availablethe BIOS was updated by System Update previouslyI have checked the BIOS settings and everything is enabled I found a system restore point from a few days ago which I think is before this started, rolling back to that allows the TB3 SW to show the controller version and a device showing in Device Manager but my monitors still dont work. A further reboot without changing anything takes me back to 'None' controller version and nothing in Device Manager. Open to the idea it could be my adaptor has died, I understand you sometimes need a TB3 device connected to update the FW (?) but I do not have any other devices, hoping to try my adaptor on another machine at head office next week to ...

Am running a T470s with a Gigabyte eGPU. Been working fine until I upgraded to the latest BIOS 1.31 the other day, and now it no longer works. The small fain of the eGPU will spin up but the main unit itself (main fan, lights, etc.) will not spin up at all.Thus far I have...1. Checked BIOS settings (No Security)2. Installed/reinstalled Thunderbolt software & firmware3. Downgraded BIOS to the last two versions and back4. Tested eGPU with work laptop & it functions as expectedI'm running Windows 10 but I believe that the issue is unrelated to Windows 10. The reason is, is that beforehand, when the laptop first boots and is still in the BIOS phase, the eGPU used to fire up immediately (lights & main fan). But I cannot even get that, which tells me the issue is not Windows 10 related.Any other suggestions before I go open a support ticket with Lenovo? I'm still under warranty at least.

Since Microsoft so cordially invited me I upgraded to Windows 10 Pro on my T530 2394-SXU. One of the "oh by the way" caveats to use my free copy of Windows 10 was the G4ETA5WW 2.65 BIOS upgrade on the T530. This Lenovo supplied BIOS ask for a password even though there isn't one and does not recognize the Lenovo SK-8825 external keyboard when attached via the 4338 dock or plugged directly into the T530. After booting I must re-plug the keyboard before it is recognized. To bypass the useless BIOS password I just press enter. Once in BIOS setup I cannot change any of the keyboard related parameters. I did a clean install for Windows 10 and so far everything else is working. Anyone have any suggestions? Can I install release 2.64 BIOS? This T530 was at 2.53. TIA for your help.Bob Helms

I (someone else had already had the problem and documented a fix) found a solution. Uncheck "Turn On Fast Startup" in the "Shutdown Settings" located in the "Define Power Buttons" section in control panel "Power Options". Control Panel>Power Options>Choose what the power button does>Shutdown Settings>Uncheck Turn On Fast Startup. This insures that all USB ports get poked correctly, fast start up evidently does not. I could not tell any difference in my start up times.
