Underclocking for overheating in Ubuntu

post #1 of 8
Thread Starter 
Hi everyone!
So here's my problem; I have this laptop, an HP dv5z-1000.
It's a piece of crap, but I need it for work etc. I have ubuntu 10.04 currently installed and updated. The processor is some kind of AMD dual-core 1.9Ghz, I believe (turion?).
The laptop often overheats and shuts off. This happens whenever I run something the computer decides is too difficult, such as Skype, converting m4a's to mp3's, etc.
I'm thinking that if I underclock my CPU, or just lower the voltage, I can make a serious improvement.
I added the CPU frequency monitor to my Gnome panel, but setting it to coservative/powersave/950Hz still doesn't help much. I've installed powernowd, but am not really sure how to use it - I'm still quite a newbie with linux.

Any help would be greatly appreciated. Thanks!

if never cleaned the heatsink and you had the laptop for a while, chances are its filled with dust and that's what is causing the overheating.

I would use CPUFreq

I used CPUFreq in order to under-clock my processor in my laptop. Unfortunately, my laptop had an nForce motherboard chipset, and I couldn't undervolt my processor with the traditional Intel methods... and that was all there was. However I was from a 2.4GHz to 1.6 drop, and that helped reduce the heat and power consumption in my laptop.

Download cpufreq from the repository.

Open a terminal as root or use sudo:
Code:
cpufreq-info
to view your profiles and
Code:
cpufreq-set
to set your profiles.

Use
Code:
cpufreq-set -h
To determine what to put in the command line.

Hybrid - you were right! All I needed was a can of air. Pretty embarrassing that I actually disassembled my laptop before even trying that. Now it runs cool and quiet.

Don't feel too bad. My daughter's laptop was overheating. Looking at it I saw that the fan had died. So I ordered a new one, about $10 on ebay (I know, I know, what a rip). After disassembling the machine and removing about half of the parts to get at the fan (it's a Dell), I discovered a gob of lint stuck in it. Removed the lint and the fan burst into life. I think I probably threw the now redundant fan in the garbage in disgust.

Usually when someone has an overheating laptop, the first thing I do is clean out the fan and heat sink. Solves the problem the majority of the time, usually throw on new thermal compound while I'm at it too just to help it even more.

Though I have repaired a few laptops that just run hot no matter what.

Nice 3 year necro post.
