HP DV4 Intel schematic for Compal board LA-4042P, provided as a 1.85 MB PDF. Compal uses the LA- prefix for its motherboard numbers, so confirm the code and revision on the PCB, since DV4 models were built on more than one Compal design. Technicians use the sheets to follow the power-up sequence, check the charger and regulator outputs, track down the component behind a short and trace signals between processor, chipset, memory and I/O. Any PDF viewer opens it.
