On all my Mac Noteboks, an I-book G4 and an Intel Macbook, there is a round ‘Button’ cell soldered in on the m,ain board which retains rudimentary start up information. I have replaced this cell on both my laptops after about 5-7 years, which seems to have solved similar problems to what you are experiencing.
