Inspiron 1100 cpufreq

I setup cpufreqd on my laptop to try and control speed, mostly to prevent heat issues.  I've noticed that no matter how I setup the /etc/conf.d/cpufreq it always stays in performance mode when plugged in , however when I unplug the AC it goes down and switches to on demand, is there a seperate configuration somewhere regarding laptops that I need to setup?  I'd like it to listen and throttle down on AC when not doing anything.

Re: Inspiron 1100 cpufreq

Did you enable your cpufreq in /etc/rc.conf? Also, I had such trouble, because I use my own build of kernel. It includes cpufreq in kernel, but cpufreq script expects module. I corrected it and all became good.

Re: Inspiron 1100 cpufreq

Info in the wiki. The most import think is that after you modprobe the desired cpufreq modules you edit /etc/conf.d/cpufreq . There you can select the desired governor:

#configuration for cpufreq control
# valid governors:
#  ondemand, performance, powersave,
#  conservative, userspace
governor="ondemand"

# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="1GHz"
max_freq="2GHz"

The name of each governor speaks for himself. Also you don't need to set valid suffixes - they're automatically detected.

It's settings, but you need activate its. Part of /etc/rc.conf:
DAEMONS=(syslog-ng network !netfs crond alsa acpid dbus hal ntpd cpufreq )

Re: Inspiron 1100 cpufreq

I have modprobe'd the appropriate governers  and cpuqfreq drivers, it runs but my config file is overwritten, anytime I go  to battery it's immediately throttled down, but when I'm plugged in it rarely does, and usually when I need it at full speed.
