My buddy bought a 1.5GHz PowerBook G4 new in the box from the Apple Store 5 years ago and it came with a 45w ac adapter... I was always under the impression that PowerBooks needed 65w chargers? 
I know one time my battery died on my PowerBook and I tried a 45w charger and it wouldn't even start up.
