Compal schematic for board LA-7901P, revision 1.0, packed in a 1.20 MB RAR archive. No notebook brand or model is named, so match the board number printed on the PCB before using it. Compal, the ODM using the LA-xxxxP numbering, supplies boards to many laptop brands. The diagrams are used to follow power rails, the power-up sequence, charger and EC signals, and component values when tracking down a fault. Combining it with the LA-7901P boardview makes it easier to find the physical parts referenced on each sheet.
