Pls help ID this Dock! Weird Part Number

[WizardOfBoz]

I have my W530 in a Mini Dock that has a part number SD20A23328 04Y2074. The dock looks like a 433835U, with the 170W "butterfly" power socket, 1x VGA, 2x DVI, 2x DP graphics, and 6x USB 2.0, 1x USB 3.0. I think it has the 4338 marking on it.

The parts compatibility listing doesn't even include this part number (infernal Lenovo!). It works great with my W530.

Is this, indeed, a 4338-35U?

Thanks!

04Y2074 seems to resolve to this: http://support.lenovo.com/en/documents/migr-72873 I say "seems to" as Google returns this URL when given 04Y2074 as a search term but it doesn't (now) appear on the page. Nor is that FRU embedded within the HTML code.

4338-35U is ThinkPad Mini Dock Plus Series 3 with USB 3.0 – 170W: http://support.lenovo.com/us/en/documents/pd024298

Ray,

This is why its weird. I have one of these. It's a 170W unit (butterfly power socket) with the blue USB 3.0, which I 've tested and it communicates at near USB3.0 specs. So I don't think it's a 433810U, as that unit doesn't have a USB 3.0 port.

Would a 433815U, which has a blue/USB3.0 port, be this unit? Do the 90W units have the butterfly power socket? If not, then by spec and appearance, and apparent function, it should be a 433835U. This was sold to me as a 433835U. I guess I should let sleeping dogs lie if it works...


Thanks, Jim

The following variants of the Mini-Dock Plus are available:

4338-10U: 90W PSU, eSATA
4338-15U: 90W PSU, USB3
4338-20U: 135W PSU, eSATA - the dock body should be essentially identical to the -10U
4338-30U: 170W PSU (butterfly plug), eSATA
4338-35U: 170W PSU (butterfly plug), USB3

So yours can only be the last one.

I think you are right, dr_st, but Lenovo sure doesn't make it easy, eh?

Thanks,

Jim
