Duplicate of the Compal LA-7731P revision 0.3 schematic, again a 3.14 MB PDF. The name gives no brand or model. Compal uses the LA numbering for motherboards it makes for various laptop vendors, so the same board can appear under different brand names. Technicians use the document to follow power rails, locate components around a short, and understand EC and chipset signal routing. Since r0.3 is an early revision, compare the PCB markings and component values carefully before trusting it.
