Solved Boots From Battery Not From Power Cord Powerbook G4 Aluminum 17 1 1 67 Ghz

Chosen Solution

I rescued the machine in question from being tossed in a dumpster. It will power up if I charge its battery in my own 17" PowerBook first. But it will not start up without the battery when I plug the power cord in, nor will it charge the battery. The power adapter I tried is the original that came with my (identical model) 17" PowerBook. I’m thinking the DC-in board needs replacing.

That’s a very good guess. I’d do it.

I concur with the others here, this is the part you need.

The DC/In Board is a good place to start, but what power adapter do you have? is it a 65W or a 45W, if it’s a 45W, the PowerBook can only charge off of it, and not actually run, the 65W can run, and charge at the same time.
