How do you underclock with linux?


Once I get my laptop set up I want to underclock the CPU because it runs WAY to hot and eats WAY to much battery power.

Its a 2.6 GHZ CPU and I want to get it down to say.... 1 GHZ.

When I was using windows xp I would just use a tool called "CPU eat and be cool". Is there any linux programs that could do something like that?

I think you mean "CPU frequency scaling". What distro are you using?

I am using Damn Small Linux on this laptop.

But if you see the thread I made before this I can't seem to get my network adapter set up.

What laptop...

What is the make and model of this hot machine and is it as warm without throttling while running Windows?

Underclocking is, strictly speaking, reducing the rate of function of the CPU by changing settings in the BIOS. Do you have a BIOS that will let you over/underclock?

It was a laptop that I was given by my Computer Service Technician teacher but he made some modifications to it.

1: Added a new hard drive.

2: Added a new CPU.

I just wish he could have added more ram to it. :-/

As mentioned...

Install the package for "cpufrequtils" and you will be able to use the command "cpufreq-info" to see what frequency steppings are available and use "cpufreq-set" to manage the stepping profile and the maximum frequency of the CPU.

Google for the man pages for the commands.

OK, fine---but what does that have to do with underclocking or cpu frequency scaling?

You'll get better help here if you stick to one question per thread.
