I have a sony VAIO in a docking station and the fan speeds up and slows down intermittently as I use the unit. It sounds like a car going uphill and then downhill sometimes. Is this normal? Anyone has suggestions on this? I tried various power saversettings. The unit is plugged into the wall outlet. It has 128 megs of ram running Windows ME and has lots of drive space.

The fan you hear running is a cooling fan for the processor. The fans speed is a function of the temperature in the area of the processor. The software you are running is using the processor and the more it is used the hotter it gets and the more the fan runs. Check your processor usage and you will see that as the usage goes up so does the fan.
