Schematic in PDF form for the HP Pavilion Gaming 15 dk1 series, project GPC52, on Compal board LA-J641P. Compal identifies its motherboards with the LA-xxxxP pattern, and the number is silkscreened on the PCB. Technicians use this diagram to trace power rails, follow the power-on sequence, check charging and VRM circuits, and find the source of a short. Any PDF reader opens it. Confirm the LA number and revision on the board match before relying on component values and net names.
