Engineering schematic for Compal board LA-7731P at revision 0.3, compressed in a 1.56 MB RAR archive. An R0.3 release is an early pre-production version, so part values or optional circuits may not match a retail board exactly. The diagram is still valuable for tracing power-up sequencing, charger and regulator circuits, and identifying components on a shorted net. Compal uses the LA-number with P suffix on boards it builds for other brands. Check the PCB revision and use a RAR-capable tool to open the file.
