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.

Generally, no. It could be a physical problem with your laptop on the inside. A problem with the heatsink, maybe the thermal paste has worn away, lots of possible reasons. Does your laptop automatically shutdown after some time?
I have always used kernel-huge that comes with slackware and never encountered such problem on my laptop,, in fact it's running pretty efficiently. . however when im running windows vista, the processor on my laptop does get heated up easily (like it speeds up or something.)
My laptop CPU heated up easily, does the kernel i am using play a reason? i am using the normal kernel which come from distro, slackware 13.37 -current.
At first, there is no such thing as Slackware 13.37 -current, you are either using 13.37 or -current.
To your problem, on my desktop system with AMD Phenom II CPU (wouldn't you think that it may help if you tell us something about your hardware?) running -current I recognized that I have load the kernel module for that CPUs power-saving (powernow-k8) manually, and that I also have to set the power-saving governor for every core manually to ondemand, seems that performance is the default.
So my questions to you are:
- Which version of Slackware are you running?
- Which CPU is in your laptop?
- Are the kernel-modules for your CPU loaded?
- Which governor is activated for your CPU-cores?
- Which temperatures do you actually get (idle/loaded)?
Does it just heat up a bit or does it OVERHEAT? (e.g. when you touch it, you burn your fingers?).
A notebook should never get so hot that it hurts you. If it does, there is something wrong with the coolant system.
You have a Pentium M notebook, singlecore - so I assume its an older model, at least a couple of years old. I guess its time to blow some dust out of that old box and renew the thermal paste and maybe also some of the thermal pads, that are usually sitting onto the GPU and blocking most of the heat when they dry out.
Not overheat but heated up that i feel it is abnormal. It did not automatically shut down.
Yes, it is DELL Inspiron 700m, about 6 years now. i think cleaning need to be done too, but it might also some other reasons like modules or kernels.
Unless you've messed with the kernel since this started happening, I wouldn't put the kernel on my list of suspects. Yes there are options in the kernel to improve performance but again -- unless you messed with the kernel recently it simply isn't a logical suspect.
Also, if you haven't cleaned the dust out of your laptop for 6 years...that definitely is a culprit.

You should have GKrellM available (it comes with Slackware). First, blow out the dust. Second, raise the back end of the box about a half-inch or so (use an eraser or something) -- make sure you've got it sitting on wood or glass, a hard surface (not on a carpet or cloth). Then start up GKrellM -- you'll get a display that shows your CPU(s), processes, disk activity, Ethernet activity, temperatures, memory use, swap and a mail indicator. Right-click at the top of the display and choose Configuration, then Builtins, then Sensors and enable Temperature, Fans and Voltages (Temperatures will most likely capable of enabling, Fans and Voltages may not -- they're not available on all boxes).
You start GKrellm with
nohup gkrellm &
in a terminal window (you can then close the terminal). You can drag the display to the upper right or lower right of your screen.
Keep an eye on the display. Your processor core(s) should be running at about 1% to 2% with nothing much going on (the machine is just mumbling to itself) with X and Firefox running. If it or they are 50% or higher, you need to find out what is doing that which is where top comes in handy.
Keep in mind that the fan should come on if the box is getting hot -- if it doesn't, you may have a dead fan. If you're up to it, you can open the case (with, of course, the battery removed) and see if the fan will spin by just blowing on it or turning it with, oh, say, a pencil, a toothpick or something. Fans have really good bearings, they'll spin freely with just a puff of air; if it doesn't, if it doesn't want to move easily, you need a new one.
The main thing with laptops is they have to breath; blow out the dust, check the mechanical health, keep an eye on the GKrellM display and chase down an abnormal indicators.
