Schematic for the Compal LA-A791P motherboard at revision R0.2, in a compact 688 KB RAR archive. Apart from the board code and revision, the name gives no brand, chipset, or GPU information. The LA-number pattern is Compal's, used for boards built for various laptop brands. A technician uses this drawing to follow the power-up sequence, measure rails at test points, and narrow down a short to specific capacitors or ICs. R0.2 is a pre-release revision, so verify it against the PCB.
