Fan on powerbook g3 lombard wont spin.

okay ive kind of worried about this. The fan that has the vent right next to the pc card slot doesnt spin at all. It sometimes twitches when i start the powerbook up but other than that it doesnt move. Should i worry about this? if i should what should i do about it? can i fix it?

As far as I can tell (from other forums) the Lombard fan doesn't come on much and it only seems to come on at pretty high cpu heat levels.

The bottom of the Lombards case is used for heat release so it's a good idea to not run it when it's resting on a bed for instance (no air gap for the bottom) and to let the rubber feet prop up the Lombards bottom so there is always an air gap for the bottom.

I tried to see when my Lombards fan would kick in and I had to have a DVD playing and the graphing calculator 3D surfaces demo running for the fan to kick in.

If you really need it there are replacement fans at

its very common that the controller in those dies and the fan never comes on, thus cpu dies with it if its hot enough. i have never had mine come on and ive done so much CPU intese things with no problems. i dont think it even pulls much air, may not be needed unless room temps are very high. the other thing you could do is the PCMCIA hack with stealing 5v from inside the laptop to make it run all the time.
