Hi Lars,
right. when doing nothing, or hardly anything, it sits around 70 or so. dow=
n to 40/50 if I'm on the train... so it does seem to work, just not when fu=
lly powered.
What I haven't configured at all is powerd (so it's using the defaults)...=
I've been wondering how all the components that I listed before interact wi=
th each other...for example, i don't want my CPU to be eating cycles (and p=
ower) @ 2 GHz when I'm doing nothing.
I'll try your suggestions (kill cpufreq,tweak powerd to see how it goes ).=
=20
BTW, how does one use/enable/configure speedstep features?
my CPU is=20
CPU: Intel(R) Pentium(R) M processor 2.00GHz (1995.01-MHz 686-class CPU)

thx :)
