I checked all the specs. 45 watts, 24v DC out. So going by that, it should have worked. The PowerBook plug is different from the iBook plug, so I had to make my own patch wires. I used the wires from the multimeter. I checked the polarity too. Inside is +, outside is -.

I'm about 80% sure that I connected the wires correctly from the tip of the power adapter to the DC plug on the iBook. Well, I got a spark on the adapter tip as soon as I touched the + wire to it. I also heard a crackle from the iBook side. I smelt the usual burning smell of failure, coming from the iBook DC in.

I think I toasted the iBook's DC in, but I'm not sure. The battery is dead, so I can't turn the iBook on.

But my question is, shouldn't the black PowerBook adapter have worked? This is the same one that powers a 5300ce.
