an update is available for your BIOS (F.13). 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

.

Thank you for your understanding.

Title:
  scaling_max_freq always on lowest

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  I have HP EliteBook 8440p with quadcore CPU, using Ubuntu 12.04 and Gnome-Shell 3 using two bateries.
  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.
