Schematic in PDF form for the Compal HAL00 project, board LA-2791P, revision 1.0. LA-prefixed numbers identify Compal-designed notebook boards, which are sold under various laptop brands. The circuit sheets show power sequencing, rail voltages, charger and regulator circuits, and the wiring between the chipset, EC and BIOS chip, making it the companion to the boardview of the same board. Any PDF reader will open it once extracted. Check that the PCB is printed with LA-2791P and revision 1.0 before diagnosing from these pages.</div>
