An 860 KB RAR archive containing the schematic of the Compal LA-2231 motherboard, revision 0.3. The revision marks an early engineering drawing, and the LA-22xx series without a P suffix belongs to older Compal notebook designs. Technicians use these pages to locate power regulators, follow signal routing, and work out which parts sit on a rail that measures shorted. Because Compal is an ODM, the board can appear inside laptops of different brands, so read the number on the PCB and compare it before relying on the circuit.
