My TP 600 type code is 2645-510 according to the sticker and the upgrades were the following (not very old stuff as can be seem from the dates):

- Battery MaxiMiser and Power Management Features for Windows 2004-02-19
- TrackPoint driver for Windows 2000/XP 2003-12-23

After these two the sound device stopped working. Currently, I have no idea why it broke up and how to fix it. The most amazing thing is that it actually worked fine right after the installation, which was actually an upgrade from w2k. Could it be possible that there was be some old driver hanging around from w2k, which got overwritten afterwards?

I also tried following upgrade but it didn't really include anything sound device related: Windows XP Supplement Files 2001-10-18
