Compal schematic for the LS-7072P LED board at revision r01, a small daughterboard rather than a mainboard. At 30.5 KB the PDF likely covers only a page or two showing the indicator LEDs, their resistors and the connector that links back to the motherboard. Technicians use it to trace why a power, charge or activity LED stays dark, checking the supply pins on the cable connector first. Compal uses LS- prefixes for sub-boards; confirm the number silkscreened on the PCB matches before relying on pinouts.
