It's worked out well for many of us in the past.

I have a T470S type 20HF running windows 10 (version 1703) that suddenly the Intel Thunderbolt Driver was updated and gives me the error "A Thunderbolt controller has experienced a problem and cannot connect to devices or other computers until new firmware is installed." The computer is connected through a usb-c cable to a dockin station which has two monitors connected through display port cables. I tried uninstalling the Intel Tunderbolt Software (ver. 17.4.78.500) and reinstalling it.I tried installing thinkpad thunderbolt 3 dock and usc-c dock driver v10017.I tried to install new firmware with the file N1WTH07W but it says "cannot find correct bin file" I still get the same error and cannot use the monitors connected to the docking station. Please help.

I tried to ask on Reddit but it looks like nobody knows the answer. trying it here  where could I find a confirmation that the T470 with onboard HD 620 graphics can drive two 4K Dell P2415Q at 60Hz monitors when connected via Thunderbolt? PSREFs just say it can support up to 3 displays (which is cool, but at what resolution and what will be the refresh rate) and max resolution supported is 4K at 60Hz (again, great, but how many of them?)I was planning to use either the Startech's Thunderbolt 3 to Dual DisplayPort Adapter or Dell TB16 dock to connect the monitors, as Lenovo is not providing ways to connect two 4K monitors over the DisplayPortIdeally, I'd love to have a dock which can connect both monitors but as I understand current generation of mechanical docks does not allow to use two 4k monitors, I guess it has something to do with bandwidth of chips used for DP ports in the docks.

I have a T470 20HD running Windows 10 Pro. Both the operating system and all Lenovo updates have been applied. Attached to thos is a Plugable-brand USB3 dual HDMI docking station that's been driving a pair of Dell SE2417HG(HDMI2) screens. Or did, until I did the Integrated Firmware of Thunderbolt Function 1.0.12.0-N1QTF16W update, at which point it now only drives a single screen. Windows sees both displays but now can't use one. I've tested both displays and they work fine otherwise, and if I unplug one display the dock will "fail over" to the other display without an issue.Is there a way to roll back this firmware update, or am I basically out of luck?

Network shares, both administrative and explicitly shared, cannot be accessed when the shares are on a laptop connected via ethernet through the new Thunderbolt 3 dock. Using the onboard NIC, WiFi, as well as the NIC on a Thinkpad Ultradock does not cause this.

Hi, I have a T470 laptop with the USB-C charger. I'd like to connect a DisplayPort LCD screen to use as a second display while simultaneously being connected to A/C power and charging my batteries. I am having a bit of trouble figuring out what my options are. 1. I could buy a Thunderbolt 3 hub/dock with a DisplayPort connector on it. I would then connect the charger to one of the USB-C ports on the hub/dock, and the screen to the DP connector. From what I can see, these hubs are fairly expensive, so given that I currently don't need to connect any other TB3 devices I'd like to avoid it if possible.2. I could buy a USB-C - DP adapter or cable, but I have not seen anything with some kind of pass-through function which would allow me to connect my charger. I thought daisy chaining was something TB3 can do, but unfortunately the charger does not have the ability to do this (I know a DP connection has to be at the end of the chain).3. The T470 has a slim tip charge port, in addition to the ability to be charged via the TB3 port. Perhaps a USB-C - slim tip adapter exists which would allow me to connect my charger to the slim tip port, and not worry about the lack of daisy chaining in point 2. I've found a different adapter (wrong interface and wrong direction), but nothing that can do this. Thanks for any info/advice!

Since January I tried to fix my Thunderbolt 3 Dock (40AC) to get it work together with my X1 Yoga Gen2 (20JE). It works nicely in the first months. Lenovo sends me a second dock, nothing changed. Today Lenovo changed my mother board, nothing changed. I changed all cables and tried any hint from support forums and our internal IT department. So different windows installation binaries was tested and all drivers as well as BIOS are the newest versions. Perhaps someone here has an idea what that means if the device manager in Windows says that the device (Thunderbolt Controller 15D2) is not connected to the computer and it is hidden. The device is not hidden and connected, that includes also then the ThunderBolt Software shows all two ports, only during the installation of the driver software or the update tool. That is really crazy. I think this is the main issue. Please check the attached screenshot. Any hint would be helpful. Thank you.

I'm thinking of getting a P70, I see it has 4 USB 3 ports and 2 Thunderbolt 3 ports.  My questions are: 1: Is each of the USB 3 ports connected to their own controller so that each port is capable of it's maximum bandwidth?  Or are all four ports connected to the same controller so that the data bandwidth is divided among the four ports? 2: Similar Thunderbolt 3 port question.  Is each of the two Thunderbolt 3 ports connected to it's own controller?  Or is the bandwidth shared between the two ports? I'm planning on using the USB 3 ports (maybe Thunderbolt 3 also) with a high end, high data rate USB 3 camera that, according to the specs, can use up 95% of the USB 3 bandwidth.  If I were to use two cameras at the same time, it would not work if all four ports are connected to the same controller/bus and sharing the bandwidth.  I have read that laptops usually share all USB ports on the same controller.  I'm hopeing it will be different with the P70, being a "professional" workstation class product. Thanks

Hello,  I have used a 40AC docking station with my 20HQ carbon machine for the last year with no issue. On Monday, I plugged in and neither monitor activated.  The docking station still provided power to my machine, but presentation was not possible.  I tried installing the Thunderbolt driver posted here. The install seems to work but when I open my device manager after restart I still don't have the Thunderbolt controller. When I attempt the thunderbolt FW update posted here, I get the error message below:FW Update errorLack of Controller in Device Manager ( with Hidden shown) Other tests: My coworker with a Yoga type machine was able to connect to my dock and use both monitors.  Additionally, I was able to test on thier dock and the behavior was the same.

My Thunderbolt controller keeps crashing and prevents me from being able to use my USB-C dock (it still charges, but no USB/displays).    To restore functionality, I have to shutdown, hold the power button for 10s, then boot up, but that's only a temporary fix.  The controller inevitably crashes within minutes/hours of booting up and I have to repeat the steps.  Sometimes my external displays continue to work after the Thunderbolt controller crash error comes up, but if I undock/redock they don't work.  I've updated my BIOS (N1MET52W), Thunderbolt driver (17.4.78.500), Thunderbolt controller FW (N1MTF25W), and USB-C Dock FW (3.7) to the latest available, but nothing has helped.  Sometimes the problem will go away for a few days then come back.  Has anyone run into this?Thanks!

Hi,
I myself own an XPS 15 9550 and noticed that I was not getting the full Thunderbolt 3 speedover it's Thunderbolt 3 port. I expected speeds around 2700MB/s, because of the overhead withthe theoretical gross speed of 3870MB/s, but I only ever got 1400MB/s out of it.
I did some digging and found out that none of the XPS notebooks with Thunderbolt 3 are evenable to achieve the full TB3 speeds, because they are only connected with two PCI Express lanes (x2.3).You can read more about this on the following links:Dell Subreddit PostChipset Digging on Forum

Thunderbolt 3 and the promised speeds were the MAIN REASON I even bought this notebook.I feel very cheated here.

Is an m.2 sata 2280 compatible with the adapter that come with t470? A ssd like  GREEN M.2 240GB ? the pins seems different buy i read that they are compatible (but slow). Thank you

Because I didn't liked USB 3.0 ethernet chipsets and USB-based ethernet cannot bear some network-intensive tasks, I wanted to use PCIe-based Thunderbolt ethernet controller on my XPS 15 9550. As there is no Thunderbolt 3 "PCIe" ethernet adapter (except docks), I chose to buy Apple Thunderbolt 3 to 2 adapter and Thunderbolt 2-based ethernet adapter.
I plugged it into the XPS 15 9550 (tested with BIOS 1.1.19, 1.2.14, 1.2.16 and latest Thunderbolt firmware with NVM version 16), and the PCIe device did not pop up. Instead, only USB billboard device is appearing saying that "Alternate Mode configuration not attempted". Both Windows 10 and Ubuntu 16.10 failed to detect the device. I moved this configuration to MSI GS63 laptop, and it detected ethernet controller successfully (that laptop utilizing NVM firmware version 18).
It seems that other vendors are affected with lower NVM firmware version involving setup with Thunderbolt adapter: see the case of Lenovo too. Do you have planned Thunderbolt NVM firmware update for XPS 15 9550? Looks like XPS 13 9360 is using newer Thunderbolt NVM firmware version, though.

I just got my X1 Extreme yesterday. I updated the BIOS to 1.15 and also updated other drivers. The one pending thing is the Thunderbolt firmware update utility. The first pop-up says "do not connect any Thunderbolt device", but then a second pop-up right before the firmware update says "connect at least one Thunderbolt device. I cancelled the update for now due to the conflicting pop-up messages. Note - I do not have any Thunderbolt devices connected to my X1E laptop. Can I upgrade Thunderbolt firmware safely with no Thunderbolt devices connected, or?

Hello,the thunderbolt on my X380 Yoga completely stopped working. As I try to connect a P27h for instance, the laptop charges but does not recognize the monitor or USB Hub.I installed every update available on system update and tried to update the Thunderbolt Software and Firmware. The software installed fine but upon updating the firmware the following promt appears:    When I check the version inside the Thunderbold software, this is what shows up:    I am running Windows 10 Home 1803. Any idea why this is not working? Is my thunderbolt controller not working properly?Thanks

A:Thunderbolt not working / Unable to update thunderbolt firmware

There is an issue with the update for the tunderbolt firmware when updating through the system update utility. This is a known issue that the Engineering department has been working on. The only known resolution to this issue so far has been to replace the system board. Im sorry for the inconvenience this is causing. If the device is still under warranty i would speak with the support center to have a tech install a new board.

Hello, My T470 is hanging when attempting to boot. It hangs on the "Lenovo" screen and  then eventually enters "Boot Menu". I ran the lenovo diagnostics and it threw an error code: START TESTS 20181124T213405UTC START STORAGE_READ_TEST 20181124T213410UTC STOP STORAGE_READ_TEST FAILED 5 S STOP TESTS UHD020020-UN7W0I --- STORAGE FINAL_EXECUTION  FINAL_RESULT_CODE U1THPBDV2-ZD1LE2 Does anyone know what this means? This is on an SSD. Any chance of data recovery? I have no idea where to find information on this error code and no idea how to contact lenovo for information/tech support (all contact pages just seem to be pointers to resources, these forums or order support).  My machine is out of warranty (standard 1 year, purchased ~1.5 years ago) but I did buy with amex with plan that it would cover me for an extra year. Does anyone have experience with this process? What information I would need to get to have amex cover the repairs.  Thanks!Ben

Hi, I got a new T470 a few weeks ago and everything was working fine. It is running Windows 10 Pro. Yesterday, the computer restarted itself and went straight to a blue screen with the "whea uncorrectable error" code.Everytime I try to restart the computer, it is directly blue screening. The automatic repair fails (blue screen), booting from a Windows recovery DVD fails (blue screen) and everything else fails as well. Does anybody know how I can fix this?  Thanks.

A:[T470] Blue screen (WHEA uncorrectable error)

Not good... You might try going int to the BIOS and resetting it to the setup defaults... but if you are getting a BSOD even when booting from a recovery DVD, you can rule out device drivers or a corrupted Windows OS installation as the cause, so that pretty much leaves only one other possibility, which would be bad hardware such as a bad CPU or system board etc..    Since it is under warranty, I would call support at 877-453-6686 and open a ticket.       Best of Luck,
