Schematic for the Toshiba Satellite A80, based on the Compal LA-2811 motherboard, in an 894 KB PDF. Compal prints its LA board numbers on the PCB, so confirm that the code and revision match the title block before using the drawing. Technicians use it to trace power rails and verify charger and regulator operation. It also helps follow signals between chipset and connectors and find components when isolating a shorted rail. A regular PDF viewer is all that is needed to open it.
