SONY VAIO VGN-CS21S/P - the fan switches on and off frequently

\015 The problem:\015\012the fan on the left side makes a lot of noise (switches on and off every minute 2-3 times for 10-15 seconds), but it starts to do that only when I go online (I tried with WI-FI and mobil internet).\015\012This is why I could not reproduce the phenomenon when I took it back to the shop where I bought.\015\012The noise is just annoying, especially when switching on - I can hear a loud blowing which is very disturbing when concentrating while working.\015\012The shop said that I should set the BIOS. It is not really something I would know (how could they expect that from a woman?) I will call the service tomorrow, but I would like to know more as soon as I can. We have a 3 days changing back guarantee here in Hungary, and I would like to hear ASAP if this is a type-error of this machine.\015\012\015\012Any comment about it? Thank you in advance! :-)\015\012\015\012Orsi from Budapest (Hungary)\015

Answers :

It is good that the fan is coming on and off, and there is no bios setting to change that. The reason the fan has to run is to keep the machine cool so it won't burn up.
