ThinkPad Ultra Docks - Difference between models

Question

Hi, Can anyone advise whether the only difference between the various thinkpad ultra docks models is just the power rating on the adapter? Will I be able to use a 40A20090 ultra dock with a 170W adapter in conjunction with a laptop that requires a 170W adapter. Thanks.

I am half kidding: you are missing a normal expectation.
Whatever, whenever, wherever you are, do not trust advertising. They are about bragging, they don't have to be real, they only tell you how good it could be and never let you know about how bad they may be. But they usually don't dare to lie much, so take them as a reference.
In your case I believe you are expecting too much from X1 and T420s. You should actually try them out before order. It is easy to understand the reflection, it is because of the Corning Gorilla glass. It is a big pro but also brings about a few cons I think I can generalize every piece of your disappointments into this, like the heat and noise are because of the much improved computing power. You just have to think it through before buying.
And to the difference part. Quality cannot be measured without time. That is the difference.
Anyway I am not selling Thinkpad, I am just a fan. I understand that actually the brand is not as shiny as before, but it is still the greatest to me.
