Toshiba Satellite A30 circuit diagram supplied as a PDF, for Compal board LA-1931. The name also carries DBL10 and Sapporo, most likely Compal project codes used internally for this design. Expect pages covering power sequencing, the charger, CPU core regulation and peripheral interfaces, which are useful when tracing a short or a missing rail with a multimeter. Any standard PDF viewer will display it. Check that the LA number printed on your mainboard matches, because Toshiba shipped one model name on different boards.
