I have a 2645 as well (it's a 600E), and I experience this as well. sadly, I have no insight, since I haven't investigated--even with APM turned off, the screen does go entirely black when I close the lid, so most of the time I just do that. > Furthermore I'd like to know the most elegant way to turn sound on on an > TP600 (Type 2645). How did you solve this issue. I have this in my kernel file: device pcm options PNPBIOS for 4.7-STABLE FreeBSD 4.7-STABLE #14: Wed Dec 18 07:53:23 PST 2002 there's no problems running, but there is a seemingly intractable bug in the interaction of the sound driver and APM--if you suspend the system, sound doesn't work when it wakes up. I asked freebsd-mobile@ and the information (including from Warner Losh) was that the pcm driver is not APM-aware, and I'm not sure if it's even possible to fix. I also haven't had any luck running pcm/csa as loadable modules, although other people did, so it's possible I gave up too soon. I was going to suggest checking the archives, but I can't find the threads. maybe you'd have better luck.
