Have you tried to change the default power setting for your video card? |

I have this card: |

and have this little file auto-switching my video cards fan from running non- |

cat /etc/local.d/set_radeon_power_profile.start |

Apparently, the binary fglrx driver manages power switching more effectively, |
57 |
but with the radeon driver you'll need to switch it yourself. I can't recall |
58 |
what I might have had to enable in the kernel, but if you can't get it going |
59 |
let me know and I'll poke around my .config. |

almost 4 years old. Since I've set it to auto for video card power management |

the battery last longer. |
