Should my laptop be so slow?

It could even just be a wall of dust blocking airflow out of the chassis. Find instructions online on how to open it up and make sure that the fan(s) are all clean. If you're feeling adventurous, you may also want to remove the heat sink from the CPU to verify that there is enough thermal cooling liquid (and that what's there isn't dry, cracked and useless). I'm speaking from personal experience as I just had to do this process a couple months ago for a laptop of mine. The wall of dust, which wasn't really visible from the outside, was disgusting and mighty.

OK... giwrg98 and oldtimeyjunk, CPU temp at 100 C level is f*** up, it's NOT normal, consumer processors and laptops are NOT designed to operate at these temperatures, no matter what quality it is, no matter what price tag it is, no matter if it's 10years old laptop or new one. And I don't know what's the cause of it but you really should check what the hell is going on.

PS these temperatures are at idle or load? If you leave laptop in BIOS for longer time what temps are reported?

PSS giwrg98: did you tried Ubuntu live cd as we talked earlier?

It makes lots of noise and whenever I turn it off, I have to wait for about a minute to turn it on again. If I try to turn it on too soon, it will turn off imediatly. I am now about to check from the BIOS.

My laptop gets to these temperatues - it gets to 96 celcius, but in Windows it told me it was running at 104 celcius. Most of the time, it's caused by build quality which cannot be fixed; or a faulty fan; or a blocked fan that's full of dust.
But, I've been running MATE with lower specs -1.73GHz, but because of temperature, it brings me down to 800MHz unless I force it to go back up - and at high temperature, I saw no significant slowdown except when running Flash videos.
How do you know that it brings you down to 96 Celsius and how did you bring it back up?
EDIT: Right now I have 100 C!
EDIT2: Also, almost every time I wait and turn it on, the screen is black and it does not even show the Compaq icon in BIOS so I am forced every time to turn it off from the power button and try again.

It's called CPU Scaling. In MATE, I had an addon that allowed me to choose between different CPU Frequencies. You can also do it from the Terminal.

I've taken it into PC World time and time again, only to get it back with the same heat problem. Last time I gave it back, they gave me my original Windows Vista installation (yuck) and they broke the web-cam. From what I can remember, it's been like this ever since I bought it.

And every time I ask them, they reply with the same answer, "Oh, it's normal for laptops to get quite hot after prolonged use,".

My laptop gets up to 96 celcius in less the ten minutes!

Something else I noticed as well, typing "acpi -t" brings up this...

Thermal 0 ok, 96.0 degrees C

Thermal 0 OK? Hmmm...

Also, I don't know if anyone can answer this - couldn't find anything on the internet. On my laptop there is a button that has a Fan symbol on it, and below the keyboard there is a Fan light next to the power light. In Windows Vista, I think it forced the fan to turn on. In Linux, it blinks and then stays on; and when turning it off, it blinks, and then goes out. However, when it is turned on/off (blinking), the temperature jumps down to 78C, then quickly rises back up to 96C.

Is there any tools that can "catch" these button presses so I can find out what it is.

Ok, this is very strange. With the Ubuntu 12.04 Live CD the output of sensors is:

acpitz-virtual-0
Adapter: Virtual device
temp1:       +256.0°C  (crit = +105.0°C)
temp2:        +30.0°C  (crit = +105.0°C)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +78.1°C  (high = +70.0°C)
                       (crit = +100.0°C, hyst = +95.0°C)

Isn't the CPU temp the k10temp-pci-00c3?

Is sensors configured correctly? On my machine, I get more output and this includes information about the current fan speed.

Or maybe the fan isn't being detected properly?

Hmm, I will try again with the defaults
