Thinkpads Forum

I have just received a 4337 docking station which I bought here http://www.ebay.es/itm/151957696947, and I'm trying to dock my x230, but it is like impossible, it just does not fit.

It looks like the "plastic parts" which have to take their place in the holes of the laptop are fitting on them, but at the same time, there is a gap between the docking connectors.

The laptop also does not look to be fitting at the base:

I don't know if there is any problem with one of these parts of the docking station:

Any ideas?

Welcome to the Forum, roxor.

The reason it doesn't fit is because this particular model does not support the x230, only the x220.

You need the ThinkPad Ultrabase™ Series 3 (0A33932) for your x230.

EDIT: I stand corrected by dr_st below. I was originally referencing an outdated Lenovo accessories list.
The 433715U and 433710U are indeed compatible with the x230.

See: https://support.lenovo.com/us/en/solutions/migr-4tpjf4

That's not true. The X230 and X220 are supported by the same docks.

Could it be that the dock is stuck in a locked position? Does the eject button depress fully when pushed down?

Hi dr_st and USSS,

Many thanks for confirming docking station compatibility!

1. For everyone's information, we have used the "ThinkPad Mini Port Replicator Series 3 (Product no: 4336-xxx)" [the 2nd item in below link as you folks supplied]:

2. From personal experience, our T410 and X230 were fully compatible with the "ThinkPad Mini Port Replicator Series 3 (Product no: 4336-xxx)".
From deduction, one would imagine that the X220 would also be compatible with above Mini Port Replicator Series 3.
Thinkpads like to plan their Port Replicators to be compatible for several generations.
