In the early days of acpi, I had a quirky laptop. The work around for me at the time, was to use the laptop a while until it heated up, then reboot. Grub would start the fan and it would stay running after control was handed off to linux. Surely we're past those days. You might check for firmware updates on the device which corrects it if it's software based. Otherwise you probably have a failing fan and you got "lucky" under windows. The odds of getting "lucky" under linux is likely to be equally as good.
I have 3.11.0-24-generic kernel. What do you suggest I do? It's the latest kernel update for the distro I am using. I am willing to change my distro but I think that all of the recent ones use the same kernel.
Leave it for the moment. If you get desparate, grab the kernel source, load your config file (usually /boot/config-version) into the top source dir as .config, and rum make allmodconfig
Then fix it to compile in everything you need to get going - unless you have an initrd you can use. That will have modules for everything. I ran into the issue that sensors-detect couldn't load kernel modules (Thet were not there), so it couldn't find devices.
Well, I just tried to install and configure the fancontrol program, but by the time I ran the pwmconfig command, it said that I didn't have pwm-capable sensor modules installed. even though the sensor command detected some pwm devices.
It doesn't seem to have anything there to help control the fan and make it work whenever the computer gets hot. I was wondering if it was in the bios but there doesn't seem to be a setting in there for that. I am getting the new fan installed to see if that may be the case as to why it keeps stopping and making my laptop get hot. The fan works it just keeps shutting off randomly when booted in Linux and when it gets hot it doesn't turn on. I also want to know that even if the fan control hasn't been set, what is my computer set to as far as temperature to control the fan whenever the circuity reaches a certain temperature and decides it needs to turn the fan on.
Temperature looks normal to me though. ~45 C is normal operating temperature I presume. If you think this is hot then what according to you should be unhot?
I have an HP Pavilion g6 laptop. My fan runs full speed when I turn it on, and then slows down when the OS starts to boot. Whenever the CPU temperature goes up beyond 60 C it goes up to top speed, and once the temperature comes down, it slows down too. I assume this is normal operating behavior.
it might not be showing it but the processor is getting really hot (the region of the laptop on the left side of the mouse pad, When I opened it to check out the fan, that's where it was. I think the fan is controlled by another sensor that isn't close to the processor). This still looks like a case of a processor processing what it doesn't need to process and getting hot in the process. the cpufrequtils package didn't seem to do anything because the processor is still running hot even through it's not supposed to be doing it. I'm only word processing and that doesn't demand much effort on it's part.
it's starting to look like an HP problem. the fan only seems to work when it wants to. I rebooted it several times (unintentionally I was just trying to start it in windows to see if it will run cooler but after splash screen and booting back into Linux the fan starts working again). I already updated the bios and it did seem to do some good since the fan is more reactive (and with the replacement fan it also seems more reactive whenever it want to be).
I just had the same problem 2 days ago, which caused my hp to overheat & shutdown within 2 minutes oif starting. I took it apart & no the vents weren't clogged but the fan has a cover over it that you have to remove & there you will find a large dust bunny which you'll have to remove with a wire because the fan doesn't come apart from the cooler. Also be very carefull not to lose the small black ribbon clips.
Also keep laptop off of blankets when in bed.
I'm starting to see that I am too used to the fan being on all the time. The processor seems to be heating because I want to believe that it's heating (although you can still feel how hot it is when you touch it before all of this fan business). the fan seems to have a mind of it's own but I never really noticed when it starts to work and under what circumstances that it decides to do so. I think it's detecting heat or maybe it's just trying to screw with me. I'm not entirely sure. I'll work with it for a while to see if the overheating stuff keeps coming up.
What would you consider to be a bad temperature for the computer. When I posted the temperatures after running the command to find them I was told that the temperatures were normal. What would you consider abnormal temperatures that would make the machine turn it's fans on.
Is there a way to set it to where the fan will start on a specific temperature in which you set in the operating system. the cicuitry (assuming the ones away from the temperature sensors) get really hot and it needs to make the rest of the computer hot before the fans turn on. I was wondering if there was a way to set it to where the fans are on all the time. The sensors aren't showing the computer is hot, even though it is hot and I can feel the heat eminating from it as my hands type this message. I want to find a way to set the temperature in which you want the computer to turn the fans on.
I'm exploring this a little further, the fan only seems to run when the computer is plugged in. I checked the bios and there doesn't seem to be a option to keep it running when on battery. Some further investigations are needed.
Running XFCE here, largely for it's 'low cholesterol' approach. It has it's power manager which thinks it's the acpi daemon and will adjust all of those things. Watch out for scripts in /etc/acpi/somewhere called by events in /etc/acpi/events and of course buried BIOS settings
