HP laptop schematic for the Compal LA-8661P board, with QAU30 given as the project code. Compal prints LA-numbers on its PCBs and is a major ODM for HP notebooks, so this number identifies the mainboard more reliably than the retail model. The PDF lets a technician follow power sequencing, inspect charger and PWM regulator circuits, locate components and trace signal nets during no-power or no-boot diagnosis. No revision is stated in the name, so compare the board number and revision on the PCB with the title block first.
