PDF schematic of about 1.08 MB for the Compal LA-A992P mainboard; the suffix in the name suggests a duplicate copy of the same document. No brand, model or revision is stated. Boards marked LA-xxxxP come from Compal, which produces them for multiple laptop vendors, so the code printed on the PCB is the matching key. Use the diagram in a PDF reader to follow power rails, study the power-on sequence and identify parts around shorted lines. Compare revisions before relying on resistor or capacitor values.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @alischematics. Enginerys does not host this file.
