I just purchased a new T400 2764-CTO which has the discrete video. I replaced a three year old T43 with a screen that failed. Lenovoi told me my two port replicators for the T43 would work on the T400. That proved to be an error. So now I am in the market for a T400 port replicator. I am looking at the Lenovo Thinkpad Advanced Mini-Dock 250410U. I have purchased two power supplies and so do not need another power supply. I don't trust Lenovo for an accurate answer.
My questions: Can I purchase an Advanced Mini Dock without the power supply? And secondly, will this Mini-dock work with the T400 2764-CTO. (I am running Vista Business as my sole OS.)
yes, 250410U is the correct part number for the advanced mini dock compatible with the T400.
it is sold with an a/c adapter and unfortunately cannot be purchased separately. you could, however, resell the adapter if you don't want it. forum.thinkpads.com has a free marketplace if you're interested.
