I’m using Compaq laptop CQ40-115AU,spec show in my signature. Now with 11.4 KDE x86-64,harddisk heat grow very high and fan will suddenly spin like hell for around 3 minutes,sometime can heard a ‘tick’ sound,then the screen gone blank,just shut down like that. I never turn on the desktop effect. This never happen in 11.3,I’m worried how long my laptop could last with suffering this heat.
Anyone face this problem? Any solution? 
sounds like a heating problem where the fan doesn’t cool enough and the computer shuts down because of excess heat, even if the cpu’s were running full throttle the machine should be able to cool itself.
Google’ing shows some posts complaining about overheating with this model - something to look into
I would test with a 11.3 cd or other live cd and see if it still happens, this will will show that is/is not a hardware problem
running top and iotp, do they show and strange and large uses of cpu and ram?
found a post on how to clean it but seems difficult and maybe dangerous (laptops are a **** to disassemble) *(http://www.fixya.com/support/t3531078-compaq_presario_cq60_215dx_notebook_pc)
you could try a laptop cooler but it that worked always need to use it*

would you happen to have a backup of your 11.3 /boot/grub/menu.lst, it
is a long shot but i’m thinking maybe there is an acpi= statement in
there which works for your machine…
well, what happens if you boot “Fail Safe”, it that give you better
heat/fan control then do this in a terminal and put it on

sudo cat /boot/grub/menu.lst

Seems the problem been solved,so far.
I found something in my System Process yesterday,it is ‘akonadi contact’,over 30 of them,flooded in my system process,each consume 3MB of memory,I don’t like it & post a help,an expert gave me a solution to remove them,I did,now my harddisk stop the overheating,seems ok.
I don’t know whether these ‘akonadi contact’ stuff fried my harddisk,but at least I don’t have to put a table fan beside my laptop…

Just for your info: most computer shops have air pressurized cleaning devices to clean your laptop. Don’t do this yourself.
Hi,
I have a 2 laptops (Acer) and it is really straightforward to clean it yourself. Unless you have a very special model, you always have to unscrew a panel beneath the laptop and it exposes the fan and the stuff you need to clean (grils). There is pressurized can to do it. It is fairly easy.
I f you are unsure, go to youtube and you’ll find a lot of video tutorial showing how to do it for a lot of model.
It depends on the make, model and year - not all laptops have accessibility to much more than the ram and hard drive without a fair amount of dis-assembly.
I am sure you are right.
