Thought I'd add that
a) I'm using 'speedstep_centrino' and haven't tried 'acpi_freq' - should I?
b) Uninstalling powernowd makes absolutely no difference to the problem -
only when it's installed and I ca

I have the same problem I think the machine is an Asus A8V clone (AJP)
My CPU sits at 100% when on AC - but scales correctly when on battery. I've

I've attached my lspci output and uname as given above.

I didn't know that the commands you make with sudo and those under sudo

So I done that and... no ameliorations... it's always the same...
# echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
Yes ! We're on the way of a solution (maybe)
I didn't try to switch to battery. So when I'm on battery the Ondemand
and Conservative auto scaling works well !!
Maybe it's a matter of laptop-mode ? Is it enabled by default ?

I have the same problem on my Asus Z71v. Speedstep is supposedly

It's very strange... everything just used to work fine with Edgy, Dapper

When I run those commands the behavior seems the same but now the applet
don't show any changes (if the CPU is at 100% or at 46%, the icon don't
change). I only see the changes with the command : cat /proc/cpuinfo |
grep "cpu MHz"
So it don't solve my problem...

Thanks,
we now know where the problem lies.
For the kernel group you need to provide some more information:
Output of lspci -vv
Output of lspci -vvn
Output of uname -a
There were quite a number of updates that were made to the kernel that
will be available as of tomorrow. Please check if the pro
Yes, you must have root privileges. Just do a sudo -i before, and then the two
commands I gave you (no need to sudo those). When finished type exit.
Be careful that you will have full powers over your system with sudo -i (kids,
don't try this at home).

I done what you tell me but... there is a problem :
$ sudo echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

We can check if the problem lies with the cpufreq-selector utility or
with the cpufreq modules.
Remove the CPU frequency scaling applet, and run the following commands:
sudo echo ondemand >
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scalin
Try with these two commands and tell me if you see any difference:
modprobe -r speedstep_centrino
modprobe acpi-cpufreq

speedstep_centrino 9920 0
freq_table 5792 3
speedstep_centrino,cpufreq_stats,cpufreq_ondemand

gives no answer
So the answer is speedstep_centrino
Do you have a solution ?

Is your cpufreq driver "speedstep_centrino"or is it "acpi_freq"?
You can check with an lsmod.
