Thinkpad t23 cooling fan issue

My Thinkpad t23's cooling fan kicks off about 5 seconds into the
up process and fails to turn itself back on.  Everything else works
good, except the battery fails to charge.  I'm running Windows XP.
I've had the motherboard out and everything looks good with the
solder's, etc.  I'm at a loss.  I've ordered a new fan, and hopefully
that takes care of the problem, but i suspect it is something else.
Any advice on this subject would help greatly.

The fan might be old enough that the small bit of lubricant has dried
out and the fan seizes after only a short run.  A new fan will obviously
solve this problem.

You could install a utility like Speedfan that has diagnostics about
what what is controlling the fan, the voltage, CPU temperature,etc. Many
older mainboards did not include access to these data, so you might be
out of luck, but Speedfan is free, so no harm in trying it out.
