I received my Powerbook back from repair. Neither the Apple store guy nor I could decipher what was fixed on the machine. The parts list is as follows:
SUBASSY, AP EXT/BT, 11CHNL,Q85 FLX CKT ASSY, BT,WIRELESS,PB15" RETURN: Within Specifications PCBA,LIO/SOUND,PB15" FLX CKT ASSY, SOUND,IO Q16C
The returned item was the battery, as there was a separate page saying that though the battery wasn’t optimum, it wouldn’t be covered. We also deduced that the Airport card was probably replaced. It looks like the sound card may have been replaced.
If you can decipher any of these items, drop a note in comments, and my thanks in advance.
