laptop fan always on

My own laptop fan only comes on intermittently but my mate's is always on - this can't be right, surely? And maybe it's why his battery lasts a lot less longer than mine too. Any ideas how I can change the setting to intermittent? I've looked in the BIOS and device manager but frankly don't know what I'm searching for! I heard it might be a faulty sensor but desperately hope we don't have to have it fixed because it's a Tiny/Time one (yes, I know; I did warn him!)

It depends on CPU is in the Computer, is it a P4 by any chance

A can of air, hairdryer(set on cold) or a floor cleaner (set to blow), through the laptop's exit hole should be a simple start.

It is surprising how much fluff one can collect!

well that's an entertaining one to try, certainly! Mind you, it's only a few months old.

...to see if anyone else has any ideas. Went into the BIOS - it says Intel celeron CPU2.40GH but can't find any reference to fans. Power saving is enabled (whatever that means) is the fan on device manger to have a look at? what's its 'proper' name? Or is it that some laptops just always have the fan on?

Some fans just come on when you boot up, others are thermostatically controled and as such operate intermitantly. I don't think it can be adjusted through software.

Laptops have very cramped interiors and some have the fan running all/most of the time - perhaps just as well at this time of the year when temperatures are quite high in any case.

Looks like he will have to put up with it it's one of those things. I have a celron 2.2Gb laptop but it's not on all the time

Is it a mobile chip or a desktop one in his laptop. If its a desktop one this would help explain the reason why the cooling is always on, I have a mobile chip in my laptop and the fans are nearly always running but they speed up and slow down depending on what I'm doing.

I don't know the difference between a mobile chip or a desktop one but if you tell me where I can find which one it is I'd be able to tell you then.
