Schematic in PDF format for the Compal LA-4101P notebook mainboard, about 1.12 MB. The name gives only the board code, without a brand, model or revision. Compal uses LA-xxxxP numbering for boards built for various laptop makers, so the silkscreen on the PCB is the matching reference. Use it to follow the charger and system rails, check the power sequence, locate the embedded controller and identify components around a fault. Confirm the board revision corresponds to the document before trusting values.
