Laptop schematic in PDF for Compal board LA-E841P, with CTL51 given as the project code. Compal uses the LA-xxxxP numbering for its motherboards, and that number is printed on the PCB, so match it and the revision before trusting the pages. The diagrams help with tracing power rails, checking the charging and EC circuits, and finding the cause of a short. Any PDF viewer opens the file, and searching for component designators speeds up diagnosis.
