Hello

 

We have a Dell studio 1700 laptop and for the last few days the fan has been running pretty much non-stop.

 

I seem to remember this happening about 5 years back but can't remember what I had to do to sort it!

 

Can anyone help at all?

 

 

Thank you

 

 

 

Oliver.

I recommend getting some canned air and blowing through the intake and exhaust (through the plastic). If dust gets built up, the fan will run but will move little or no air and this causes heat build up. Try this first and let us know if it still runs non stop.


If I am helping you with a problem and I have not responded within 48 hours please send me a PM.

Hello

 

I gave the laptop a good clean about 3 weeks ago and this started last week but guessing I may have caused it as a few blasts of air and we are back to normal.  I will remember that for the future - Keep it simple!

 

Thanks for your help.

 

 

Oliver.

Be careful blasting any fan, when they are spun up by canned air they produce electricity and can damage your board.  It is important to insert a plastic stir stick or similar to hold the blades from spinning.

Yeah, as oldphill said, motors turn into generators when actionated by an external force!

I never recommend over speeding fans by the use of high psi air compressors, I have seen a few shatter or break. I have never seen damage done from static by dusting out a computer as of yet and I have dusted well over 1000 computers, laptops, desktops etc. I guess it is something to keep in mind as a possible cause of failure. I did once see damage after someone used a vaccum and physically knocked of main board components, they must have been rough with it.
