It has been a while since I worked with Lenovo systems, but in the last job I had, that is all we used at our company.
From what I remember, if you go to Lenovo's site, and put in your full model #, you should be able to find the exact drivers for it. By full model #, if you had a T400 laptop, you would have to tell them thinkpad T400, machine type 2768, and model 11g. That full number, (in my example 2768-11g) should appear somewhere on the laptop. If I remember right, its on the bottom of the unit.
Once you have that, you should be able to go to this page
and then start the process to get you to arrive at the drive download page for that unit.
If you see the attached picture, that is what I come up with if my laptop was the one I was using as my example (T400, Model # 2768-11g).
