Possible workaround: I have improved the temperature of my laptop a lot, by doing the following: 1- setting Trip Points and Polling Frequency in /etc/rc.local, as described above: echo -n "105:0:85:50:40:35" > /proc/acpi/thermal_zone/THRM/trip_points echo 10 > /proc/acpi/thermal_zone/THRM/polling_frequency
2- following the information in the UbuntuGuide.org website about SpeedStep for my processor: How to enable your CPU's Power Saving/Frequency Scaling features http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_enable_your_CPU.27s_Power_Saving.2FFrequency_Scaling_features I chose the OnDemand governor. My laptop is a Sony Vaio VGN FS315M, with Pentium-M 1.73Ghz. I am running the 386 kernel, because this laptop seems to have issues with the Generic kernel. It now runs most of the time at 798Mhz, but it increases the frequency quickly as needed. It is feels more responsive than before, when I just used the Trip Points and Polling Frequency. However, it is very obvious that the fan is still not being used as much as I would like. Ideally, when the laptop is plugged to main power, I would like to set it on Performance mode, and use the fan as much as possible. When I do: cat /proc/acpi/thermal_zone/THRM/* I see that there is absolutely no information about Active cooling Trip Points. Once again: if I need to provide any info to anybody working on this problem, just let me know. Which makes me wonder: who is working on this? Any idea of when a new version of the kernel will come out, hopefully with some improvements? -- CPU overheats during high usage "throttling <not supported>" https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
