PDF schematic identified only by the Compal board number LA-C701P. The file name gives no laptop brand, model or revision, so identify the target machine from the title block inside the document. Compal uses the LA-xxxxP pattern for mainboards it builds for several notebook brands. A circuit diagram like this shows power sequencing, rail names, the EC and charger circuits and connector pinouts, which helps when measuring missing voltages or tracing a short. Open it in any PDF reader and check that the number on your PCB matches.
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 @cidschematicandboardviewofficial. Enginerys does not host this file.
