Hi,

sorry for the late reply. As usual, I have had to travel and did not get a chance to connect to the Internet.

let me tell you my experience. I have had a horrible experience with 9. I mean, horrible compared to what I normally experience with FreeBSD. I simply did not get it working at all. As I needed the machine, I installed Fedora 16. At least it worked. I was most happy when I could install FreeBSD 10 and it worked after I did not need that machine that urgent for work anymore.

Let me compare;

How did you get this value? No battery inserted? The range should be from 0 to 100.

I have 0 here.

Mine runs currently also on AC.

I do not have anything with IBM or Lenovo.

I also did not load anything specific for the X220 except of the Intel KMS module.
