Does anyone know if the internal connector on a Barrel DC-in board and a Magsafe DC in-board is the same connector? I realize this seems like an inane question but my sister (due to her complete ineptitude) keeps snapping the cables and connectors on her iBook G4 so rather than get her *another* adapter, i'm thinking of just filling the hole closed, sawing out a magsafe connector and replacing the DC in-board. It probably seems like a daft idea but after the 5th adapter and second DC-in, i've realized she isn't going to learn to stop stepping on cables, bending pins, crushing barrels, straining molded connections etc. etc. This just seems like a more long-term solution..
