Case fan rpm problem, error msg on boot up

\015 The BIOS doesn't recognize the case fan, it is running, but in the BIOS it show's 0 rpm. This causes and error msg. on boot up.\015\012I have no motherboard layout map.\015\012Any ideas,\015\012Rick\015

Answers :

Please try to replace the fan and after replacing it, reset the bios.
another way is to change the position of the fan's power source.
This is not that unusual, I have an HP with the same sensor error on it's PS fan. Generally you can disable the warning if you know the fan is working by going into BIOS and poking around.

\015\012If this is not an option in your BIOS, you can try simply replacing the effected fan as it is difficult to test which has failed, the motherboard sensor or the sensor in the fan.
\015\012
\015\012When you replace the fan $10, it will either continue on it's way or give you the error, if it still gives the error, comment back with the make and model of the board and we'll see what else we can do for you.

PS - I don't know if I entered the right IBM style (I don't have my laptop with me)...I purchased it in 2003 and it was the thin one of the two offered.
