I've been trying to purchase a couple of 433815U docks from my usual vendors, but I'm told Lenovo has discontinued those. While I'm sure these could be found somewhere, Lenovo suggested that the current T440 series dock 40A20090US "might" work for us. I'd rather buy a current part over a discontinued part, so . . . has anyone found that the T431s will work on this new UltraDock from first hand experience? If it doesn't, we'll just use a USB type replicator. Thanks,
Jim

No, the new dockings wont work with the T431s - only the old Series 3 port-replicators work.

I would recommend to buy one of the old docks. USB 3.0 docks are not very good, they cause many problems.

Yes, I've also found that USB docks can be troublesome. Thanks
