Schematic in PDF form for the Toshiba Satellite A70, with the name pointing to Compal board LA-2301. Compal uses the LA-xxxx pattern for its laptop mainboards, and Toshiba sourced many Satellite models from that ODM. A technician can use these pages to follow power rails from the charger input through the system regulators, find signal paths between chips and work out why a board refuses to power on. Opens in any PDF reader. Confirm the LA number and revision silkscreened on the PCB before trusting values or component references.
