Thinkpad P50 compatibility with ThinkPad Thunderbolt 3 Dock

I am considering to add a dock station to my Thinkpad P50.

I have seen that Lenovo is starting to sell a new shiny ThinkPad Thunderbolt 3 Dock (40AC0135UK).

It doesn't seem to be available in the Uk Lenovo Shop but I have a found a distributor who's selling the product.

Is the ThinkPad Thunderbolt 3 Dock compatible with Thinkpad P50 ?

 

Thanks

Re: Thinkpad P50 compatibility with ThinkPad Thunderbolt 3 Dock

Hi LeftyX,

Welcome to Lenovo Community! And happy to have you here.

As I understand that you have query whether Thunderbolt 3 Dock is compatible with ThinkPad P50 or not?

Looking at the Lenovo Options Compatibility Matrix it is not compatible with ThinkPad P50

 

I hope the above information helped you. 

Please feel free to post in Lenovo Community Forums if you have any further queries!

 

Regards,
Prabhansh

Re: Thinkpad P50 compatibility with ThinkPad Thunderbolt 3 Dock

Hi Prabhansh,

 

I've seen that compatibility matrix, hence the reason I am asking.

I don't understand why it cannot be compatible.

The Thinkpad P50 has a thunderbolt 3 port.

Is there any other thunderbolt 3 dock station compatible with my Thinkpad P50 ?

 

Thanks

The main reason being its not compatible with ThinkPad P50 as this uses USB Type-C Gen 1 and Thunderbolt 3 dock requires USB 3.1 Type-C Gen 2. So therefore it will probably not work with your system

 

I hope the above information helped you.

 

Cheers, 

Prabhansh

Re: Thinkpad P50 compatibility with ThinkPad Thunderbolt 3 Dock

Why does USB-C version (5Gbps vs 10Gbps) matter for Thunderbolt 3 ( 40Gbps )? Thunderbolt 3 ports in P50 and P70 do work at 40 Gbps.

I was quite interested in this myself, however the documentation ( https://support.lenovo.com/ca/en/solutions/acc100356 ) states that it shares the same fault the Workstation Dock has: it's still impossible to connect two 4K monitors via DisplayPort and run them both at 60Ghz. At least not without Thunderbolt 3-> DisplayPort adapter.

Re: Thinkpad P50 compatibility with ThinkPad Thunderbolt 3 Dock

Hello Prabhansh,

 

I couldn't find any Lenovo specs on my Thinkpad P50 but I've found this site which states the the port is actually a USB 3.1 port (Type-C, Gen 2).

Do you have any link to documentation where I can check what type of Thunderbolt my system is mounting ?

 

Thanks

Looking at psref of Lenovo P50 it only states that system is occupied with USB Type-C / Thunderbolt 3. Chances are there that Thunderbolt 3 Dock may work. But the only difference I found that newer system in which Thunderbolt 3 Dock is compatible are all having USB 3.1 Type-C Gen 2 / Thunderbolt 3 port.

Re: Thinkpad P50 compatibility with ThinkPad Thunderbolt 3 Dock

Hi Prabhansh,

 thanks for your help.
I've spent these last 2 hours trying to figure out what type of thunderbolt port my P50 has and what
compatibility there is with other thunderbolt docking stations.
Disappointed about Lenovo. Spent tons of money on this machine cause I wanted support and fast
help and still have to do figure out things myself.
Do you know if there are any other Thunderbolt 3 Docking Stations compatible with ThinkPad P50 ?

Thanks

Re: Thinkpad P50 compatibility with ThinkPad Thunderbolt 3 Dock

P50 has Thunderbolt 3 port. USB version does not matter. If you get Lenovo own Thunderbolt 3 dock, and some Thunderbolt 3->DisplayPort adapter, you should be mostly in Lenovo-supported territory.

 

There are some more details about 3rd party docks in  https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/tp07_en/thread-id/56737/page/3 . HP and Startech seem to work, with Startech technical specs explicitly mentioning P50 - https://www.startech.com/uk/Cards-Adapters/Laptop-docking-stations/thunderbolt-3-laptop-dock~TB3DK2D...

Hello again, 

 

Had a word with Lenovo & they confirmed ThinkPad Thunderbolt 3 Dock will not work with ThinkPad P50 or any workstation as dock can only provide 65W power which is not sufficient enough to power P50 or any workstation.

 

I hope the above information helped you.

 

Cheers, 

Prabhansh
