Compal schematic for the NAL70 project, board LA-4106P, revision 1.0, in a 3.37 MB PDF. NAL70 is the Compal internal project code and LA-xxxxP is Compal's numbering for mainboards, which appear in laptops sold under several brands; the name does not say which. Technicians use this to follow the power-on sequence, trace standby and main rails, and check EC and charger circuitry. Before relying on it, read the LA number and revision from the PCB silkscreen, as different revisions can change components and values.
