It is true that if I boot my machine with attached power cable (BIOS version A20) the fan is always on. After removing power cable and attaching it again after one minute the fan stopped to disturb me. Strange solution but it works! :-) Thank you for your tip svctr!

After a while the fan stopped. Actually I had 3 minutes left. Since I currently have a very old battery that just stays alive for a couple of minutes I cannot say whether this would help others (fan going off could be caused by some "remaining time event" or a "X minutes on battery event"). I'll check with a better battery then... For anyone who stumples upon this:

Ubuntu runs smoothly after tweaking the usual things. However, if running Compiz the UI is still terribly slow. Almost like on my 4-yr old notebook. Hope they'll fix that pretty soon. @Peter: I bought the T400, quite a decent device. Ubuntu runs smoothly after tweaking the usual things. However, if running Compiz the UI is still terribly slow.

I only expected a !quite! laptop and so I was disappointed. It would be really interesting for me to see (or better hear) this T400, because it was one of the others I could have choosen from. To get more silent one you should choose the cheaper but old Dell D640 (ups, I don't know the linux support :-|). A friend of mine had such a thing - nice! And you can use it for programming and such, but slower than E6400 ... they should send you the E6400 + the T400 and then you can choose :-) > have to feel like I’m disturbing

That's a whole lot of money. I don't want to sit in the library (where it's always super quiet) and have to feel like I'm disturbing the others. But I'm starting to think that there is no perfect notebook for Ubuntu. The Thinkpad T400 (which I'm also interested in) has two graphic cards (= switchable graphics), but Ubuntu doesn't support it - btw. Windows 7 doesn't either. What is it with those manufacturers. Shouldn't they build devices that work for most OSs? @Peter: That’s exactly it, — when I buy a laptop for ~1500€, I really like everything to be as expected. That’s a whole lot of money.

I works very well (like I described in my blog entry). And the fan is not loud, but always on. This is the same under windows! I am sure you will have (different) problems with any laptop out there with linux, because no device manufactur will support linux until 2020 I guess ;-) Although with the fan stuff in my dell this is a bit ugly for such an expensive device ... :-( Hey, I don’t think that ubuntu is not supported.
