The Tools Used list specifies a #6 Torx wrench, but in step 7 it says a 1.5mm hex wrench is preferred. This is good to know ahead of time since a #6 Torx wrench is not available from the local hardware store, but a 1.5mm hex wrench is.

Thanks you guys. I never thought I could fix my own Mac 'till I came here. I did have to mix two different procedures as the inside of my PowerBook G4 was not exactly like the one in either.

Thank you!

Great guide - i fixed my PB G4 1,67 without any troubles. My DC-in board had a burned through capacitor. Now it´s loading again the battery and recognizes the powerplug.

Thank you!
