Macintosh LC 630 General Maintenance diffhist +1,713 Josh talk contribs (Battery section corrected: the '4.5 battery' in Apple's symptom chart is a section cross-reference, not a voltage - the same manual prints '5.4 battery' for the same step and the Performa 630 Series manual prints '5.4' in the identical entry. Apple names no battery part, voltage or threshold for this machine, so none is asserted; 742-0011 is still correctly excluded)
