Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

The preferred interface is located in the sysfs filesystem. If you
mounted it at /sys, the cpufreq interface is located in a subdirectory
"cpufreq" within the cpu-device directory
(e.g. /sys/devices/system/cpu/cpu0/cpufreq/ for the first CPU).
cpuinfo_max_freq : this file shows the maximum operating
frequency the processor can run at(in kHz)
and a couple other things/hints
i put the kernel documentation as it is a kernel thing so if it changes in the future you know where to look
note you probably need to set it as root
also check out powertop, its a great tool for power saving
Thanks to you both. Yes, I have checked everything, and I'm sure it isn't a problem with dust. The fan vents are perfectly clear. This thing just runs hot. It also has a really loud, annoying fan, so I also always use a separate cooling mat underneath it to cut down on fan noise. AND I have an extra-large battery in it, so it is propped up at an angle which allows air flow underneath. Just take it from me: do not buy an HP Pavilion laptop.

I don't know if this is your case or not, but this is just a general note about a "cooling mat" that includes fans.
Assuming a laptop has it's air intake or exhaust opening(s) on the bottom and not the sides, you can have a situation where the "cooling mat" and the laptop are fighting each other rather than blowing the air in the same direction. That is, the "cooling mat" may actually be impeding airflow through the laptop.
I will agree with tobisgd that you might need to make sure that you have the correct driver for your video. On my laptop with the neauveau driver it has a real problem with overheating. Do a lspci and look at it to make sure what driver you need. Then do a lsmod to check what module is loaded.
Are you sure that the heat is even generated by the CPU? It also could be the GPU that produces the heat, for example in case of a Radeon GPU used with the free radeon drivers.
Sorry, my subscription preferences were messed up and I just saw these last few posts. I'm sure no one remembers this anymore, but to answer your question, the reason I was sure it was the cpu was because when I set the max cpu frequency under Windows, it eliminated the problem. Without it it would overheat and shut off. Thanks for the idea.
Tracy, my cooling mat is not causing the problem. The cooling mat was my response to the problem. The laptop just runs hot.

That way you can still use full speed in short bursts.
Here's the config file I use with an HP small form factor desktop PC that has the same problem.
Thanks for that. Might try it if I ever need more performance. I used the solution of cpufreq-set to limit the maximum cpu frequency to 85 percent, and that has made it cooler.
