ThinkPad Series 3 Docking Stations with USB 3.0

As of June 2012, variants of the docking stations with USB 3.0 support have been released. They are identical to the original docks, except each has a single USB 3.0 port, distinguished by a blue color. The USB 3.0 docks can be identified by the 433x-x5x part number (as opposed to the 433x-x0x of the original models).

The following docks are available with USB 3.0:

• ThinkPad Port Replicator Series 3 with USB 3.0 (433615W)
  • One of the four USB 2.0 ports replaced with USB 3.0

• ThinkPad Mini Dock Series 3 with USB 3.0 (433715U - U.S.)
  • One of the six USB 2.0 ports replaced with USB 3.0

• ThinkPad Mini Dock Plus Series 3 with USB 3.0 – 90W (433815U - U.S.)
  • eSATA port replaced with USB 3.0
• ThinkPad Mini Dock Plus Series 3 with USB 3.0 – 170W (433835U - U.S.)
  • eSATA port replaced with USB 3.0

It is unknown why Lenovo chose to sacrifice the eSATA port on the Mini Dock Plus instead of one of the USB 2.0 ports as on the other docks. This means, unfortunately, that there is no docking station in this series supporting both eSATA and USB 3.0.

Supported Thinkpads and USB 3.0 compatibility

Each of these docking stations supports the same Thinkpads which are supported by the respective original models. However, the USB 3.0 functionality is available only on the Ivy Bridge Thinkpads, and an the Core i7 variant of the X220, which includes a third-party USB 3.0 controller where special provisions have been made to support the USB 3.0 docks. With all other models, the USB 3.0 port will only function as USB 2.0.

Modification for X220 Tablet

Kaze22 wrote on forum.thinkpads.com:

I tried docking my X220 Tablet to my W520 Series 3 Plus Dock today, didn't work cause the stupid alignment blocker was in the way.

I ripped the blocker preventing the X220T from attaching off with brute force.

Problem solved, it works like a charm, saved myself 150 bucks on a ultrabase, now I have a series 3 dock that supports all the laptops with no blocker.
