PDF schematic covering Compal boards LA-A972P and LA-B972P, 1.19 MB. The file name gives only the LA-A972P number with no laptop model, so identify the notebook from the board itself. Compal often uses neighbouring LA codes for variants or companion boards of one project, which is likely why two numbers are linked. Open it in a PDF reader to follow power sequencing, trace rails and signals, and locate components or test points when hunting a short. Confirm the exact code and revision on your PCB before relying on part references.
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 @schematicslaptop. Enginerys does not host this file.
