Schematic diagram in PDF format, 3.80 MB, for Compal motherboard LA-D891P. The name states only the board number; LA-prefixed codes belong to Compal, which builds boards for brands such as Dell. Circuit diagrams like this let a technician follow power sequencing, identify rail voltages, check enable and power-good signals and see how components connect. Pair it with a boardview of the same board for physical locations, and confirm the board number and revision silkscreened on the PCB match.
