So I have a Aluminum power book that's hard drive has crashed on me and the battery is shot and won't hold a charge past 3 min. I think I've come to the realization this computer is dead. I submitted it to ifixit.com to see what they would pay me for it. It is a: 1.5 GHz PowerBook G4 Aluminum 15". and they offered me $400 for it. Is this a decent offer? Could I get more for it?
