Laptop overheating

While any activity CPU temperature greatly increases. So cpufreq sets for it minimum frequency (it's 800MHz for me) and I can't work with laptop. If I disable cpufreq, BIOS turns off laptop.

My MODULES and DAEMONS sections of rc.conf

MODULES=(powernow-k8 cpufreq-ondemand cpufreq-powersave)
DAEMONS=(syslog-ng crond hal fam @cpufreqd @alsa @networkmanager @bluetooth @kdm)

/etc/conf.d/cpufreq

# valid governors:
#  ondemand, performance, powersave,
#  conservative, userspace
governor="ondemand"

# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="800MHz"
max_freq="1900MHz"

Re: Laptop overheating

is your cpu fan working correctly when the temperature increases?

Re: Laptop overheating

Try setting the conservative governor, I use it on my laptop and works fine. Only steps the CPU up to the highest when really needed. It's better than ondemand. I use powersave when I'm on battery power too. Laptop-mode-tools can automate this for you too just a heads up.

from wiki

Note: This is not the same thing as cpufreqd. Never run both cpufreqd and cpufreq.

My point is it is either a typo, or you have wrong daemon set in your rc.conf.

cpufreq is for cpufrequtils, I believe that's what you're using (due to conf and modules). Use Powertop to check your CPU frequency on the fly.

BTW, how high the temperature goes? More details abour your laptop? Maybe you need some additional scripts/modules to increase fan performance, I did.
