T42 CPU scaling limited

I have a IBM T42 Laptop with got acpi running.
I can control the speed of the CPU stragely only
1.80 GHz
1.60 GHz
1.40 GHz

I'd like to be able to trottle it down to 600MHz, thats also what's the value of /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq : 600000

An other try would be cpudynd but that stops with:
cpudynd version 1.0.1 Copyright: Ricardo Galli <gallir@uib.es>
cpudynd: CPU frequency control disabled
Error: Nothing to do, exiting

I've read alot in this forum and can't find any advice here or elsewhere. Hopefully somebody knows.

Thanks

Re: T42 CPU scaling limited

you could try using powernowd just to check if it works, it workes alot better than cpudyn (in my opinion)
it is in the aur

Re: T42 CPU scaling limited

I have the speedstep-centrino module loaded, if that's what you are meaning.
powernowd is for AMD processors according the manual and the homepage.

Re: T42 CPU scaling limited

powernowd is a daemon (just like cpudyn) (it is in the aur) I did not mean the module big_smile


(it might however be a module as well, but it is not what I meant)
