My new G4 Dual /10.2.4 is showing me the date as Dec 31,1969. When I reset the date manually, it reverts back to this date. Today I replaced the pram battery but I still have the problem. Can anyone suggest an answer? Should I zap the pram or try resetting the motherboard? Can I do these the same way I did on my G3? TIA, David Whelpley
