[Bug 1074362] Re: [HP g6-2245sg] high core temperature cmakes fan run frequently, brings down time on battery


Mario Veygel, as per
an update is available for your BIOS (F.26). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change

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.

  [HP Pavilion g6-2245sg Notebook PC] High core temperature makes fan
  run frequently, brings down time on battery

Status in “linux” package in Ubuntu:

Bug description:
  This is a newly installed Kubuntu 12.10 on a new HP g6-2245sg
  notebook, dual boot with Windows 8 which was pre-installed.

  Under Ubuntu the cpu fan kicks in frequently even if the cpu is idle
  (according to various system monitors. The  HW temperature applet
  shows the temperature going up to 56°C, then the fan kicks in and
  brings it down to ca. 48°C. The fan stops until the temp is up again
  to 56°C, where it kicks in again etc.

  When booting Win8, the idle temperature is stable at 40 °C, and the
  fan never runs unless the PC is busy long enough that the core temp
  goes into the 50°C range, which only happens when playing videos etc.

  This is not only annoying because of the fan noise, but also reduces
  the battery runtime significantly compared to Win8.
