Description Casper Pedersen 2005-10-28 15:58:43 UTC 
Hardware: Dell Latitude D610

When I unplug the AC it sets the CPU freq to 800mhz which is correct, but when I plug the AC in again it stays at the same speed. The powerstate is correct (performance -x reports "Performance     active  AC_default_scheme"), but it seams that it does not write the correct information to /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq & scaling_max_freq. If I echo the correct number to these files the CPU speed will go to the correct.

My /etc/sysconfig/powersave/cpufreq & scheme_performance are set to default values. ALLOW_THROTTLING="no"
Comment 1 Michael Gross 2005-10-31 16:49:34 UTC 
I suppose the syslog would be helpful. So please attach 500 lines of /var/log/messages. To me this looks intended. Does it work if you set ALLOW_THROTTLING="yes"? Please try this first.
Comment 2 Casper Pedersen 2005-10-31 17:00:16 UTC 
There is nothing in /var/log/messages. And 'ALLOW_THROTTLING="yes"' does not work. 

I've attached a dmest | grep -i acpi which have a few errors in it.

Please don't compress attachments. Specially small ones.
And we still need the syslog. There might be indications of what this problem is about there.

/proc/acpi/ac_adapter/AC/state shows the correct state.
