So my laptop was working just fine but after a whole day of usage
everything slowed down, my physical memory was 89% full, and the
openoffice did not want to start at all.As soon as it happend I knew
the problem is I did not hear the cooling fan.
After shutdown about a hour I turned back on and everything was
working again very fast.I hope I didn't brake anything!
Here are the spec about the laptop::
Toshiba Satellit A15-S157, 2.2ghz proc, 512mb ram.
I installed FreeBSD 4.10 on it, adn I use KDE desktop.

Is there any built in or third party program I can install to turn on
the cooling fan when is necessary??
Or do I need to make some change in my installation??

Thank you soo much for all the answers.



I'm pretty sure the cooling fan is hardware controlled (at least for laptops), and that no change you do to the system will affect the cooling fan in any way. I know that if you put your laptop in your lap, it can overheat (your thighs certainly do after a while!), especially if you place it on a pillow or some other soft object that prevents air from circulating properly around your laptop. Another thing, leave your laptop plugged in (i.e. to the power grid) whenever possible, as things like fans and such usually run at lower speeds or in shorter intervals when the laptop is running off of the battery.

Have you checked the BIOS for any cooling fan settings? Switch them on if they're off or not at full speed. Try placing the laptop flat on a table and leave it running. If the laptop still overheats, my guess is that it's a hardware problem.

Hope this helps!
