P70 USB 3 and Thunderbolt 3 Port Controller Questi...

Q: P70 USB 3 and Thunderbolt 3 Port Controller Questi...

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

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.

I just got a P50 with the M1000M and a Thunderbolt 3 display.   I am trying to get a Startech.com Thunderbolt 3 to Thunderbolt 2 adapter to work to run my 27" Apple Thunderbolt display.   I have updated about every driver there is, yet I get "Ensure you are using the right cable" message and nothing shows up in my "attached device" list for thunderbolt (when I run the app).  I noticed that in the Device Manager there is no Thunderbolt Controller showing up also...   I am running the graphics cards now in discrete mode.  Also am running Win10.    Any help would be appreciated.  I got this computer primarily because of the Thunderbolt 3, so I could still use my old display.

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.

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!

And when I tried to open the thunderbolt software, it shows me the following warning.I tried to update the driver, but the installer said it was all ready. And then I downloaded HWINFO64 to check, I could not find the thunderbolt 3 controller under the PCI-Express X4 BUS. Is that means my thunderbolt 3 port is broken? What should I do with this? Btw, when I plug in the thunderbolt 3 dock, the powersupply is also connected, and the dock also provide the power, two power supply input at the same time, will that be a reason of the crash which also burn the thunderbolt 3 controller?

I'm using the thunderbolt port for a single connection to a Dell usb-c dock (power in, KVM out, speakers, network, etc.).  The 720 charges real slow and the battery status message (in Lenovo Settings app) states that the "AC adapter cannot provide enough power for normal operation of your computer".  The Dell usb-c docks are powered with a 180w power supply that provides 60w of power to the computer, which is more than the 45w power supply that comes with the 720.  I have tried 3 different Dell docks, including a Dell thunderbolt 3 dock with a 240w power supply. I have to believe this is an issue with the Thunderbolt 3 driver on the 720 or something BIOS related.  BTW, the 720 has Windows 10 pro loaded (updated from the home version loaded by default) and Bitlocker enabled.  Don't think these changes have anything to do with the issue. I purchased Lenovo's thinkpad usb-c dock (which states that it's universal) and hope it charges the 720.

As far as I know, Thunderbolt 3 allows a maximum power input of 100 watts, whereas the charging adapter for the respective device inputs 135 watts. Nevertheless, is it still possible to charge the laptop through the Thunderbolt 3 port using a high powered USB power bank? I recently purchased this laptop and discovered a dirty little secret Acer included was that once the battery reaches 41% the CPU throttles itself to 0.78 mHz which makes the system very unstable. (Bear in mind, battery saver was off, and CPU was set to High Performance, and 100% max load). I realize the charging process will be very slow, but will the device still charge? I need to know this ASAP because if it doesn't, and the CPU throttling issue still occurs, I will sell the notebook on Kijji, and purchase the Dell Inspiron 15 7559 that has a larger battery, same processor, and doesn't undervolt the CPU when you have 41% battery still remaining. Being charged $1,400 for a laptop that throttles its CPU down to the speed of a primitive Pentium 3 when the battery has sufficient charge is a total rip off.

As no-one seems to have an answer for my dual display-problems with the P50 and workstation dock, I now have a (hopefully) simple question: Is the rear P50 Thunderbolt 3 port active while the computer is docked? I wonder if I can use the StarTech Thunderbolt 3 to dual displayport adapter, and connect my two displays to this, using the dock only for USB and LAN connections. I hope someone can answer this, as I'd rather not spend another $100 on yet another useless adapter.

Does anyone know how many PCIexpresslanes are allocated to the thunderbolt 3 port on the Yoga 730 15".  I have gotten in touch with lenovo technical support, but they had no idea. I did see where the 720 is thought to have 2 lanes, but I am not sure if that is the same on the 730. Thanks for any info!

I'm having issues getting the TB16 to work with the XPS 15 9550. I successfully installed all the drivers in the proper order as documented prior to plugging in the TB16 for the first time.

I've verified that I indeed do have a Thundrerbolt port - there is a Thunderbolt symbol next to the USB-C port.
When I do plug in the TB16 the power button on it will power the system off/on.
I've used a usb-c to Displayport adapter and a usb-c to usb 3.0 adapter with a flash drive. Both worked successfully so the basic functionality of the usb-c port is working.

When I plug in the TB16 I never got an authentication window pop-up. In the Thunderbolt software it shows no attached devices.

The details setting in the Thunderbolt software looks fine, it appears to have the proper driver and firmware levels.

When I check the Thunderbolt driver it says that 'the hardware device is not connected to the computer'.
I'm at a loss - everything looks good except for the fact that nothing happens when I plugin the TB16. I'm wondering if there's a hardware problem with the Thunderbolt controller itself? I'd appreciate any help that anyone can give me.

A:XPS 15 9550 - Thunderbolt port not working - TB16

You might open the Thunderbolt software and set it to allow all devices.  I reset my system and redid the TB16 and it shows the cable and dock as approved devices.
It was not hard for me.  The thunderbolt controller is on the computer.  You show some correct info for that controller, although since I have a 9365, that specific info may be different, but you do show a different controller generation..

I just bought a new Sandisk Ultra USB Type-C Drive 64GB which is intended to be used with Type-C devices and Android phones.  It is recognized in my Android phone but it is not recognized in my P50 workstation. Am I doing something incorrectly or is this port not intended to be used as a data port?

Hello - I wish to connect my 24" Dell monitor (it has every port imaginable) to my Lenovo Yoga 720 WITHOUT using the Thunderbolt port. Is this possible? I am a Jazz musician and I with to use the external display for (1) reading complicatedf [e.g., classical piano] sheet music and (2) for use with DAWs (digital audio workstations, such as Abelton, Pro Tools, etc., where there is LOTS of info crammed in tight and a large monitor is needed). My Yoga's TB port is used for a 500 gig Samsung external hard drive.  The Samsung houses my music programs (e.g., the DAWs, Ivory piano, Easy Drummer, etc.), and I placed them there for the fast speed (this really helps eliminate the latency on the pianos).  I don't need fast speed with the monitor; my prior Lenovo G780 worked just fine with my 24" Dell monitor; the G780 had an HDMI port. I don't find a "TB dock" that has (1) HDMI, display port, etc. AND (2) another TB port.  Does such a thing exist? I've tried the crappy "USB montitors."  They (1) suck and (2) are not 24". Am I screwed here? Thanks, - Jeff Newton (Jazz saxophonist and pianist)

Hi,I am trying to hook 2 Dell U2417H monitors via the W541 Thunderbolt/mDP port. I am chaining the 2nd monitor from the 1st using its DP output port. The MST is only enabled on the first monitor as instructed. My laptop has integrated NVIDIA K1100M video card which is capable of daisy chaining.https://www.nvidia.com/content/PDF/line_card/6660-nv-prographicssolutions-linecard-july13-final-lr.p... I cannot extend to the 2nd monitor as it does not detect any signal. I know that my 2nd monitor do work. There seem to be no option to turn on/off MST from my laptop. I don't see where the problem can be. Can someone help? Thanks
