Copy of the LA-A994P schematic for Compal project ZSO50, revision 1.0, in PDF format at 1.12 MB, apparently a duplicate of the identically sized file with the same name. No notebook model is given in the name. Technicians rely on such diagrams to measure rails against expected values, follow enable signals during a no-power diagnosis and look up component values. LA-numbered boards come from Compal and are fitted to several brands, so read the label and revision on the PCB first.
