Hi, I have a G4 iBook, 1GHz The AC works, and will power the iBook, but without it, nada. Two batteries tested, that worked before I opened the thing up and successfully repaired a video issue, and the DC is non-existent. I opened it up again and double-checked every wire and everything else I could see. I could not find any info on this, the battery connector I guess, anywhere. Not on ifixit.com either. Something just went haywire, and I beg of you all to try and help me figure it out. THANK YOU!
