Fan Error but fan is spinning

#1 Post by ndee » Sun Jul 15, 2007 7:59 am

Hey there,
I have a T42p and all of a sudden when I try to start my machine, I get the message "Fan error" and after a couple seconds, it turns off.

Now, I removed the keyboard just to see if the fan is working and it actually was. So I'm wondering, what else could be the problem?

It could still be the fan (spinning too slow or not right signal going back). It could also be the motherboard

I wonder if it could also be the CMOS battery. Older Thinkpads that got a fan error code could also be caused by a dead CMOS. That would be a quick and cheap fix if that is the problem.

That's true about the CMOS battery, but when I have seen that condition, the battery has been bad enough to lose a lot of time also.

Thats interesting. Do you guys think my T30 might be suffering from this problem ?

Its been in heavy use for 6+ years, Probably last 4 years been on 24/7/365.
Before it died, it would also randomly freeze.
Also, on many occasions, when I booted up, it would ask me to set the time.

That's the classic sign the CMOS battery is shot. Replace it and you should be back in business.
