Hiya, Last night I was using my heretofore dependable 15" Al Powerbook and out of nowhere it just went dead as a doornail. Won't reboot or show ANY signs of life. Even the "Sign of Life" LED went dead overnight. I was poking around a couple of the sights that I used to fix my old Pismo when it had a similar problem and all signs point to the DC In board (which would be a relief!) i.e. everything is dead, the battery will not charge, etc. EXCEPT that the annular light on the AC supply/charger plug DOES light up. The info. I saw indicated that the connector light would NOT illuminate if the problem were the DC In board. Does anybody know if this is absolutely true? Could the charger/supply light still work if the DC In board were faulty in other respects?? I would really appreciate any help ... I'm hoping its not the logic board. On my Pismo the same thing happened many years ago and replacing the DC board gave that thing years of additional life. Thanks!
