Laptop and linux: overheating? I need help

Hi guys. I have a HP omnibook (3-4 years old). I have noticed some overheating problems when I use Linux. (Arch)
The temperature is very high, the laptop is very hot and the fan is making a noise and is working 80% of the usage time. The problem is because when I use it with Windows the fan is not working all the time and the laptop is not so hot as when I use with arch....

Is it normal to have overheating and fan noise probs with Arch more often than Windows?

Any opinions/fixes about that ..?

Thank you!

Hi,
it is not normal to have overheating and fan noise probs with Arch. Here it is running fine on my laptop. Have you start acpid and load the right modules?

Re: Laptop and linux: overheating? I need help

You probably don't have CPU scaling setup, most laptops aren't designed to run at full speed all of the time and stay cool.

unfortunatelly it is normal with Arch because after installing package for scalling it must be set up correctly manually
so follow this page and be happy:

Re: Laptop and linux: overheating? I need help

Thanks guys for all the answers. I will follow the ArchWiki guide and I will post again for the resulst. I must make some other settings or to disable/enable some modules?

I must add that my battery capacity = 0 sad and maybe it is destroyed. It is affect the system or the settings?

Re: Laptop and linux: overheating? I need help

Hi. 1) Any suggestions for the above? About my battery 0 capacity...

2) I followed the wiki and I installed the programs. I put them in rc.conf as demons and I tried to test if the cpu scaling worked but I reveived an error:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq: No such file or directory

sad

Re: Laptop and linux: overheating? I need help

 lsmod | grep cpuf

cpufreq_stats           5144  0

/etc/rc.conf

MODULES:
 acpi-cpufreq cpufreq_stats cpufreq_powersave cpufreq_ondemand...
DAEMONS:

this what is needed, then:

#  conservative, userspace
governor="ondemand"

# valid suffixes: Hz, kHz (default), MHz, GHz, THz

Re: Laptop and linux: overheating? I need help

Thanks for the answer. I have already added to rc.conf these modules/demons as said to the wiki:

load acpi_cpufreq, cpufreq_powersave, cpufreq_userspace and freq_table cause I have kernel:  2.6.23

Why yours are different?

After the reboot the check commands are Ok:

cat /etc/conf.d/cpufreq 
#configuration for cpufreq control

# valid governors:
#  ondemand, performance, powersave,
#  conservative, userspace
governor="ondemand"

# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="2.25GHz"
max_freq="3GHz"

My Proccessor: Pentium(R) 4 Mobile CPU 1.60GHz GenuineIntel

Also I added in my gnome panel a monitor and I have 2 options:
Performance/Powersave and 1.20/1.60. I think that my check is okey.

I have a destroyed battery. Is this affect the scaling? Or with AC is ok?
Also I tried to open a video in youtube and the cpu usage is 88%!!!! OMG!! Is it normal?

Thanks again for all...

Re: Laptop and linux: overheating? I need help

for v in /sys/devices/system/cpu/cpu*/cpufreq/phc_vids; do echo "28 24 21 19" > $v; done

but first

cat /sys/devices/system/cpu/cpu*/cpufreq/phc_default_vids

to get a rough idea and use the median value for the max freq (the first number 28 is the volt ID for the maximum freq, 19 is for the lowest, will be different for different processors) and decrease relatively for the next 3 steps.

80% for video is normal as long as you have an integrated GPU.

One more thing, if you are on KDE, something like KLaptop simplifies and automates all the steps. You just need to load the modules like acpi-cpufreq, and the governors you want. You don't have to start any daemon. There must also be similar apps built with something other than Qt.

I don't know how they much. I don't edit the min/max freq. It was the auto settings. What I must do now?

@schivmeister: I have Gnome. Is there a program to make this settings automatically? Because I don't understand how to find the settings for my proccessor

Thanks

Re: Laptop and linux: overheating? I need help

I had a similar problem with Pentium 4 M 1.6 GHz. I used this Wiki page to fix the problem:
http://wiki.archlinux.org/index.php/SpeedStep

In the end the main problem turned out to be a loose screw on the fan. big_smile

Re: Laptop and linux: overheating? I need help

Yes but these settings are incorrect? ->
cat /etc/conf.d/cpufreq
min_freq="2.25GHz"
max_freq="3GHz" ???

for your processor ? this one: "Pentium(R) 4 Mobile CPU 1.60GHz GenuineIntel" ?

do you see the figures there ?
Arch way is to configure all by yourself wink

Re: Laptop and linux: overheating? I need help

you could install KLaptop in GNOME. wouldn't hurt. Or try http://www.gnome.org/projects/gnome-power-manager/

Ok. But my question is what to put for min and max freq. Max I suppose that is 1.60 GHz. Correct? But min?

Re: Laptop and linux: overheating? I need help

Ok. Thanks:

My min_freq is: 1200000
and my max: 1600000

Now I put:

#configuration for cpufreq control

# valid governors:
#  ondemand, performance, powersave,
#  conservative, userspace
governor="ondemand"

# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="1.20GHz"
max_freq="1.60GHz"

And I saved to /etc/conf.d/cpufreq. Correct?

Also I have already installed Gnome Power Manager. I must do some other settings?

I think that I made it correctly. Do I?

Thanks for all the help.

Re: Laptop and linux: overheating? I need help

I think that we are wrong sad

In this tutorial:
http://wiki.archlinux.org/index.php/SpeedStep

I followed the  Setting up SpeedStep not the alternate method for the  cpufrequtils. I think that I am confused :x

@zyghom: thanks bro for the help but I have installed the first method (cpudyn acpid) and not the cpufreq...

hmm
