If I set hw.p4tcc.cpuperf_performance to 13 (the lowest available) hw.p4tcc.cpuperf follows. But I can't see wether it's slowing down the processor, and it certainly don't slow down the coolers :( > Also, have you tried APM?

I can't even get battery info from it. I didn't work much on it other than enabling it through rc.conf and loader.conf. I tried apm -e 1, but that didn't have any effect either. regards, Espen
