P50: Thunderbolt 3 dock not recognized

Q: P50: Thunderbolt 3 dock not recognized

Hi,I have a Thinkpad P50 and today my Dell Thunderbolt Dock arrived.Unfortunately, it doesn't work (= it is not recognized in any way), although Dell specifically says that the dock also works with non-Dell Thunderbolt 3 machines. I have installed the Thunderbolt software from the P50's driver site and updated to BIOS 1.17.Lenovo released an "Intel Alpine Ridge Thunderbolt Firmware" for the P70. But there's no such firmware update on the P50's site, just the Intel Thunderbolt Software from November.The 1.17 UEFI/BIOS Update says it fixed a Thunderbolt issue, but apparently not mine Has anyone ever gotten some Thunderbolt 3 device working on the P50? I just hope this will be fixed soon, because the Thunderbolt dock seems to be the only convenient way to drive three 4K displays with the P50 (2 via Thunderbolt 3, 1 via miniDP).

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

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

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

HP ZBook Dock with Thunderbolt 3 usb device issues. USB Keyboard randomly sends a stream of a repeated character.  I will be typing and mid worrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr d will get results like in the word above.  The inverse happens alot too, were it just drops a few characters i have typed. USB Mouse lag is horrible. Both devices will stop functioning, need to reboot the dock to recover them. Any one have any suggestions or which drivers are the most stable?

#HPExpertDayYou will have to update BIOS/Firmware if any. Install the docking station drivers. Try using a different keyboard, if the issue stops then issue was with keyboard.http://support.hp.com/us-en/document/bph07165

So I have an X1 Carbon Gen 5 (Kaby Lake) and the Thunderbolt 3 Dock Gen 1 (40AC0135US). I bought two 4k monitors and after several frustrating hours figured out that the Gen 1 dock can't output 4k on two externail monitors at 60hz, this appears to be a dock limitaion only. I see that you now have a Gen 2 dock (40AN0135US) that says it will do 2x 4k @ 60hz, only problem is that every compatability cross refrence I can find does not say the gen 5 X1 Carbon supports this new dock. I don't see a good reason for it not to be compatiable, but wanted to find out for sure one way or the other before I bought it, as it is not cheap.

I want to buy the Lenovo Yoga 920 (i7 with 16 GB) and I?m used to work with 3 external full HD Monitors. Since it has 2 Thunderbolt ports, it looks like the Thunderbolt 3 Dock may work with the 920. However, it is not listed on the compability list for the dock. Therefore: are the dock and the 920 working together?

As the only docking solution available and moving from a more traditional dock, its less than suitable.  HP needs to make a longer cable and the end that connects to the laptop should be at a right angle.  The cable is so stiff and thick it takes nearly 4" to make the turn.  HP makes it impossible to find this out how long the cable is with out purchasing and at that point your stuck with it.  Hardly a customer satisfaction issue they should want to propigate!

We recently started using Bitlocker with a PIN at startup. On all our laptops using the "old"-type dock, that you click your laptop into everything is working fine, the users put the laptops into the dock, turn it on, type in the Bitlocker PIN using the external monitor and keyboard, and then processed into Windows. Our problem is with everyone using the new Lenovo ThinkPad Thunderbolt 3 Dock. When the users connect the laptops to the dock using the cable and then power on from the dock, the laptop will power on (the LED in the ThinkPad logo lights up) but the monitors and keyboard connected to the dock is not working, and then after some time the laptop will power off again. We currently use a workaround where the users power on, type in the Bitlocker PIN and login to Windows before connecting the laptop to the dock, but this not a proper solution. We have Enabled both "Thunderbolt(TM) device" and "USB device" under "Support in Pre Boot Environment" in the "Thunderbolt 3"-menu in BIOS, but it still doesn't work. Have anyone else experienced this problem? Or does anyone know of a proper solution.

Love the concept of the thunderbolt 3 dock, can't fathom how it was designed though.  On my zBook 15 G3, the power and thunderbolt ports are on the right side of the laptop.  The dock has the cable port on the left rear side, completely crossing over all the ports when you put the dock on a desk with the back facing away from  you.  Then they ship a cable that is barely long enough to put the dock directly behind the laptop and connect it.   Where do I buy a longer cable HP, please!

Hello all,I bought a Yoga X1 2018 and during the shop they suggest the Lenovo Thunderbolt 3 Dock. Since I thought that having to disconnect only one cable when bringin the laptop from the desk to the meeting room would have been useful, I bought it.With my disappointment I setup everything and I did some tests on the laptop just to discover that the performance of the laptop when powered through the docking station are 1/3 with respect to when it's powered by the 65W power supply and 1/2 of when the laptop is on battery... (234pt vs 640pt vs 563pt | dock/65W/battery)Now since the docking station has a 135W power supply, I really can't think that this is an issue with the supply from the docking. Also since the laptop is even faster on battery I really don't understand how it could be related to the power supply... anyway I've connected both the 65W power supply and the docking and the performance are back to normal.Is there anyone who can suggest me what's going on or how to report this to Lenovo?

Hi allWell we all now about the fan issue which is much better since the last BIOS update.Nevertheless I have sometimes fluctuation fan noise, although there is no load. This is mainly when the notebook is at the thunderbolt docking station.I found out, that as soon as I connect my notebook to the docking station more or less all app-processes suddenly move over and start running on the GPU. The CPU has virtually no load.Why do all processes start to run on GPU when the notebook is connected to the dock? Is this an issue or is there a good reason for this behaviour?My Notebook and Windos has the latest drivers/bios and updates installed.Regards,Sebastian

I can't update my dock since it gives an error every time I try to update. I tried manual updates but BIOS files never show up, I think the problem lies with my service code not being in the system.
I tried entering the service tag and express service tag but it says it's not a valid product. If I provide the service tag and express service tag on this forum, would it be entered in the system so to speak? I also get critical updates and when I click update, an error occurs so my dock is not in sync with my XPS in terms of drivers. When I try to do manual updates, I'm only given 3 files and can't find bios files anywhere.

The X1 Yoga 3rd Gen and X1 Yoga 2nd Gen are listed as compatible. Perhaps it just means that the dock has been specifically tested with the listed models? Surely Thunderbolt 3 is Thunderbolt 3 and the dock should work with plenty of other Thunderbolt 3 machines?
