I have a noisey fan on my Latitude CPiA.  It used to be just once in awhile, now it is almost constant and getting unbearable.  I read in the archives Dell phone number which I can use and also getting manual to see if one can fix or replace fan themselves.  However I don't see where I can get the service manual for my computer.  Can anyone tell me where I can get the service manual for this Latitude online?  I bought it used on Ebay last October.  Thanks
