Laptop and linux: overheating? I need help

k3rn31 · 2008-01-22 07:31:30

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?

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:

Yeah, but that is the ArchWay

and this is what we - arch users- like ;-)

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 and maybe it is destroyed. It is affect the system or the settings?

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

 lsmod | grep cpuf
cpufreq_ondemand        7180  1 
cpufreq_powersave       2048  0 
cpufreq_stats           5144  0 
acpi_cpufreq           11548  1 
freq_table              4112  3 cpufreq_ondemand,cpufreq_stats,acpi_cpufreq
processor              28248  2 thermal,acpi_cpufreq

/etc/rc.conf

MODULES:
 acpi-cpufreq cpufreq_stats cpufreq_powersave cpufreq_ondemand...
DAEMONS:
acpid dbus hal @cpufreq...

this what is needed, then:

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="800MHz"
max_freq="2.2GHz"

k3rn31 · 2008-01-23 20:50:39

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...

how do they match ?

schivmeister · 2008-01-24 14:47:48

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

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.

k3rn31 · 2008-01-25 13:16:53

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

schivmeister · 2008-01-25 18:14:50

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?

zyghom · 2008-01-26 03:12:04

cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

k3rn31 · 2008-01-26 09:32:24

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.

I think that we are wrong

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...

zyghom · 2008-01-26 14:01:53

every way to get the target is ok right ? :-)

k3rn31 · 2008-01-27 08:11:18

Yeap. I followed the 1st one. Thanks
