Compal LA-5752P schematic, a PDF of roughly 837 KB that looks like a duplicate copy of the same document based on its numbered suffix. No laptop brand or model is named. Because Compal produces LA-xxxxP boards for several manufacturers, matching should be done by the code printed on the PCB. Use the pages to locate power rails, check signal flow between the embedded controller and regulators, and find designators for test points. Compare the revision on your board with the drawing before measuring.
