The internal buffer battery for the PRAM has ran out of capacity, same happened with my TiBook... The only way to rectify this would be to have this changed by a service technician, as the battery is most likely soldered directly to the mainboard. Will wait for the next update to the MacBook Pro line and then buy one, 500 MHz G4 is really not that fast anymore... ;-) Best regards, Michael on 05.02.2008 15:45 Uhr, Bob Fowles at rbf at psu.edu wrote: > I had the same "Reset Problem" with my original 500Mhz TiBook.
