Schematic for the Compal DAL30 board, number LA-2154, provided as a 1.17 MB RAR archive containing a PDF. No laptop brand or model is given in the name. Unpack it and open it in a PDF reader to follow voltage regulators, power sequencing and connector pinouts while diagnosing no-power or no-display faults. Compal marks its boards with LA-prefixed numbers on the silkscreen, so check LA-2154 on the PCB. A plain PDF copy of the same schematic exists in a slightly different size.
