So i followed the guides at Ifixit.com for the removal of the uppercase on my powerbook G4 15". Unfortunaely i think i might have messed something up. In the last step it said to pull the upper case toward the screen and disconnect the ribbon. Well i pulled it up a little and the ribbon, along with the tape, and a chip attached to the ribbon came off. Now nothing looks broken. The ribbon and chip are still all intact, they are just disconnected from the bottom case. Where does this little chip go? I see a silver square the size of the chip that could possibly be where it was taped on. But i don't see anywhere else the ribbon/chip would go. or did i really mess something up here? It looks like it isn't too bad.
