i've been fixing the Overheating, thanks for that, it worked, i just reopened my laptop and cleaned it VERY well. but now idle is @ 50*C and not 20-30*C, because of the frequency being at max 2.5GHz. but normaly, at idle, the freq should be very low, like @ 1.2 but when i change it on the freq scaling on Unity, it get back to 2.5.. Any help?

Ubuntu 11.10, i5 M460 @ 2.5GHz

What do you mean with "but when i change it on the freq scaling on Unity, it get back to 2.5"?

Have you triedecho "ondemand" | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor? This would normally save your last used power mode too. Other available power-mode-options are available with cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors.

  • yes, i did tryed them, well, with that, i mean, when i'm on userspace governor, i can't control the CPU freq, like, when i select 1.6GHz, it goes back to 2.5GHz is seconds... and even ondemand, it use 2.5GHz. Jun 21, 2012 at 11:00
  • do you experience this behaviour on another system as well? You might want to check that to determine if it is a software or a hardware problem.

    is the PC really idling? Use top to check that there isn't a process taking useless CPU power (because it is stuck in a loop or similar)
