RAR-packed schematic of the Compal LA-6858P board, revision R1.0, roughly 898 KB in size. Brand and laptop model are not given; Compal produces such LA-numbered mainboards for many notebook vendors, so the PCB marking is the reliable identifier. Use the extracted diagrams to trace standby and main rails, check the charger circuit, find regulator feedback resistors and follow signals between chipset, EC and connectors. Compare the revision on the board with R1.0 because component placement and values can change between revisions.
