Will this work with X220?

No, X220 requires a different dock: http://www.amazon.com/Lenovo-0A33932-Thinkpad-X220-Ultrabase/dp/B004W9BGMQ/ref=sr_1_1?ie=UTF8&qid=1419015259&sr=8-1&keywords=x220+dock&pebp=1419015261831

I think you will be fine. The vendor forgot to add the T after the X230. The key thing to focus on is the model number 3435-2TU which does correspond to a tablet pc when you Google it. Enjoy.

I have no idea! Sorry. Mine is a 255W and it works for that one. Not sure about compatibility with anything else.

I doubt it. My xe1 with 18-55 attached and the 55-200 detached barely fits. I think that the x100 would not fit at all.

If it's micro USB, probably not. I've been looking for a replacement for the X205TA, and even Asus doesn't have them (out of stock). They use some sort of proprietary interface, which is extremely frustrating!

The power from the Ultrabase does go into your X220 via another connection that is on the bottom of your machine, but if your main power port is "funky" (probably from being hit or bent) then it might be shorting inside the machine and potentially damaging other components.If that was my machine, I'd get it in right away to have the power port fixed.

This model is NOT compatible with the X240. It only fits the X220 and X230.

I do not know about the X360, however, if it has a USB input, it is likely that it will work.

Go to this link: http://support.lenovo.com/us/en/documents/migr-70299 You will see: The ThinkPad X200 UltraBase (43R8781) snaps easily onto your ThinkPad X200 Series and X201 Series ultraportable or tablet system for portable expansion.Notice it says both X200 and X201. I cannot confirm this because I have an X200 but from this it appears it will work with your X201.

I don't think so. Lenovo's compatability guide does not list this for the x1: support.lenovo.com/us/en/documents/pd014572 I don't think the X1 has the doors or slot on the bottom of it to accept the docks connector that you can see in the picture.

Although the description only lists the X240 as a compatible X series, if you go to the Lenovo site, http://www.lenovoquickpick.com/tur/system/thinkpad/x-series/x250#accessory/46405, and look at the accessories, it does list this one as a compatible docking station. I would just select one that has a good return policy and try it out. It is likely going to work but on the slim chance it won't then you can return it easily.

I just noticed that you were asking about the x25, not the x27. I would say yes, in that case.

Not positive but I don't think so, it only works for certain 5500's (not all)

In theory it should if the code is available. I'm not to familiar with that brand. I would recommend the x10 remote. It has more features.

Not sure. But fits my daughters X220 fine. Try the Lenovo site and it will give you a compatibility list.

Probably if X201E is a 11.6". I suggest that you compare the dimensions of the two computers.
