Laptop overheating, overworking, no sensors detected.

Hi all

I am having some issues with my laptop over heating and shutting itself down. My machine also sounds busy as heck no matter what it's doing.

Here is the output of "acpi -V"

Adapter 0: on-line
Cooling 0: LCD 0 of 10
Cooling 1: Processor 0 of 3
Cooling 2: Processor 0 of 10

From what I've read, it's supposed to tell me what the temperature is.

I was recommended to try lm_sensors. I downloaded it, and here is the output of "sensors detect."

# sensors-detect revision 5729 (2009-06-02 15:51:29 +0200)
# System: Hewlett-Packard HP Pavilion dv5 Notebook PC (laptop)
# Board: HP 3600

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y
Silicon Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No

Intel AMB FB-DIMM thermal sensor...                         No
VIA C7 thermal and voltage sensors...                       No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): y

Trying family `ITE'...                                      No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): y

Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.

...which takes me back to ACPI...which also can't detect much. (I'm a little confused here, tbh).

Here are my modules from rc.conf

MOD_AUTOLOAD="yes"
MOD_BLACKLIST=(pcspkr snd-pcsp)
#MOD_BLACKLIST=() #deprecated
MODULES=(powernow-k8 cpufreq_ondemand cpufreq_powersave)

and my daemons

DAEMONS=(syslog-ng network netfs crond hal)

Excuse this long post, but I thought it'd be best to be thorough. If you help me solve this I will forever be indebted to you, your children, and your childrens children.

dont forget to add cpufreq to your daemons and to check your temp run acpi -t
also with some panels you can add a temp monitor and cpu monitor to it

lewis1711 · 2009-09-19 03:22:08

Thanks for the reply.

D'oh! I added cpufreq into my daemons. It's doing a lot better, not getting as ridiculously hot as it was before, I imagine because the cpu isn't working overtime when I'm just idling.

But still, if I did want to preform some process-intensive task for a few hours, I imagine the same problem would occur.

also, acpi -t returned nothing.

Is there anyway I can set up a temperature sensors, and use that to control my fans accordingly?

Certain laptops have specific acpi kernel modules, for example asus_acpi, toshiba_acpi or thinkpad_acpi. You might want to have a look into that.

Certainly have a look at this page: http://wiki.archlinux.org/index.php/ACPI_modules

guzz46 · 2009-09-19 04:35:01

sensors might give you a temp reading

i can't control my fans either, they are controlled by the bios, on average my temp sits around 50c and if i spend a few hours compiling something it goes up to around 80c but it has never overheated and shut down before, the fans just step up in speed

Another tip would be to try and remove the dust that your laptop has been collecting. Solves my overheating problems every time
