I did become this year the old laptop from son (DELL XPS 8x i7-2670QM @ 2.2, 8 GB / 750 GB 1920x1080). It is better as my old PC (DELL Optiplex SX280 Pentium 1 GB / 500 GB alt. Laptop ACER emachines E620 AMD64 2 GB / 160 GB) and can remplace both (the emachines has a limited resolution! the Optiplex has a limited power...)
but my problem in SliTaz: the fan runs immediately intensively, the air become very warm, so I am afraid that SliTaz can be dangerous for it?
I am using SliTaz with 64 kernel.
in Ubuntu (64 bit 16.04), the XPS can run hours / all the day without any heat developement and you hear the fan extremly rarely. Idem with the most Linux versions I am trying sometimes.
what is to check, what is to do?

[c]tazpkg get-install linux64-cpufreq[/c]

Thank you!
a/ why not immediately in the Iso?
b/ I did restart. No differenz... man linux64-cpufreq > No manual entry for linux64-cpufreq
Is somewhat to do?

Try this:
modprobe cpufreq_ondemand
if no issues:
for config_file in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do echo ondemand >$config_file
done
check if the cpu slows down:
grep '^cpu MHz' /proc/cpuinfo

Hi sixofeight
Thank you very much.
Result (not really comprehensive for me):
@slitaz:~$ modprobe cpufreq_ondemand
@slitaz:~$ for config_file in /sys/devices/system/cpu/cpu*/cpufreq/scaling_gove
rnor; do echo ondemand >$config_file
> done
/bin/sh: can't create /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor: nonexistent directory
@slitaz:~$ grep '^cpu MHz' /proc/cpuinfo
cpu MHz : 2194.970
cpu MHz : 2194.970
cpu MHz : 2194.970
cpu MHz : 2194.970
cpu MHz : 2194.970
cpu MHz : 2194.970

Show output of:
[c]lsmod[/c]
[c]lspci[/c]
[c]for i in $(ls /lib/modules/3.2.71-slitaz64/kernel/drivers/cpufreq/);do modprobe -av ${i/.ko.xz/};done[/c]
then you can try again
[c]grep '^cpu MHz' /proc/cpuinfo[/c]

Hi oui
Yep, you need to load the right "power-options" module for your CPU.
Mine is a AMD, so it looks like this
before:
root@slitaz:/home/tux# grep -i mhz /proc/cpuinfo
cpu MHz : 2599.989
cpu MHz : 2599.989
root@slitaz:/home/tux# modprobe powernow-k8
root@slitaz:/home/tux# modprobe cpufreq_ondemand
root@slitaz:/home/tux# for config_file in /sys/devices/system/cpu/cpu*/cpufreq/s
caling_governor; do
> echo ondemand >$config_file
> done
after:
root@slitaz:/home/tux# grep -i mhz /proc/cpuinfo
cpu MHz : 1000.000
cpu MHz : 1000.000
root@slitaz:/home/tux#
btw
cpufreq_ondemand = the cpu-Mhz will raise if needed and go down if idle.
oh,I forgot to say that I use the 32 bit version, hopefully it's the same for 64 bit.
(sorry for my bad english)

its a little bit old
http://doc.slitaz.org/en:guides:cpu-frequency
why not to the iso - it was discussed - because it produces to much errors in log - I still vote to put it immediatly to the iso

Does underclocking the CPU reduced overheating ?
Long time ago I faced a similar issue with 3.2 series kernel on Debian Wheezy 7.0, updating the kernel solved it. Are you using a Linux 3.2.X series kernel ?
Though this may be a little odd, does the Dell XPS laptop contains a discrete NVIDIA or Radeon GPU ? I'hv seen that laptop overheating problem is due to the the discrete GPU in 99% cases.

^
--> Does underclocking the CPU reduced overheating ? <--
My cpu (2600 Mhz) is (now) using the lowest speed step (1000 Mhz), 90% of Time, during normal work.
The cpu power consumption goes down from 89W to ~22W,
and even with activated "cool n quiet" the cpu temperature is at 25 deg C.
So yes it does.
Kernel = 3.2.71
btw.
cpu scaling is something different than simple underclocking
The available speed steps,(2600,2400,2200,1800,1000 Mhz,in my case)
are automatically dialed = on demand
