If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

I noticed following: When batery comes under certain available power and/or when laptop is on power adapter and bateries are charging, until bateries are over 85% (not sure correct number), I can't change scaling_max_freq to maximum number. It stays on lowest possible freq and can't be changed. When bateries are over 85%, I can change this file. vi says : "E667: Fsync failed" when I try to save the chages. echo 2534000 > scaling_max_freq doesn't say anything, it just silently does nothing. I am using performance governor. This is my rc.local which I use to set frequencies and governour: echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo performance > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor echo performance > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor echo performance > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor echo 2534000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq echo 2534000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq echo 2534000 > /sys/devices/system/cpu/cpu2/cpufreq/scaling_max_freq echo 2534000 > /sys/devices/system/cpu/cpu3/cpufreq/scaling_max_freq And here is my /etc/sysfs.conf devices/system/cpu/cpu0/cpufreq/scaling_governor = performance devices/system/cpu/cpu1/cpufreq/scaling_governor = performance devices/system/cpu/cpu2/cpufreq/scaling_governor = performance devices/system/cpu/cpu3/cpufreq/scaling_governor = performance devices/system/cpu/cpu0/cpufreq/scaling_max_freq = 2534000 devices/system/cpu/cpu1/cpufreq/scaling_max_freq = 2534000 devices/system/cpu/cpu2/cpufreq/scaling_max_freq = 2534000 devices/system/cpu/cpu3/cpufreq/scaling_max_freq = 2534000 /etc/init.d/ondemand is disabled. I changed all this files, because I got performance problems (cpu on maximum when using firefox and laptop was draging). Then I noticed that I can set cpu (with indicator-cpufreq) to more then minimum freq, so I found out that my scaling_max_freq is also on lowest frequency. uname -a Linux 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Bug is similar to this bugs? https://bugs.launchpad.net/ubuntu/+source/linux/+bug/396432 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/242006 --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
