Is the ThinkPad X220T Tablet compatible with ThinkPad Mini Dock Plus 3 Series?

[#1]

Question

Can I check if the X220 tablet can by used on a Thinkpad Mini Dock Plus series 3?

All the info I've searched so far says it is compatible with the X220 (all) but doesn't list the X220t. 

Answer

The expansion options for the X220T are the Ultrabase Series 3 and the USB Port Replicator. The Series 3 Docks are not compatible.

Please refer to the following guide for more details.
