PowerBook 17" 1.67Ghz won't power on
My powerbook g4 17" 1.67Ghz LR model won't power up. Started with the inability to charge the battery. Bought a charger and extra batteries. Unit still worked off battery. About two months of this scenario and the unit would not power up at all. Charger shows amber but no power on. Changed out the DC-In Board. Didn't help. Could the battery on the USB card (opposite side of the logic board) be dead, preventing power on? Have not replaced this yet but thought it might be the problem as early Mac's would not start at all with the internal battery dead.
Is this a good question?
