Early-revision schematics for the Compal LA-1452 mainboard, R0.2, distributed as a 1.20 MB RAR archive. An R0.2 design is normally pre-production, and later R1.0 and R1C revisions of this board exist, so verify the PCB revision before trusting nets or part values. Compal, a laptop ODM, numbers the boards it builds for other brands with this LA- pattern. Once unpacked, the diagrams help trace supply rails, locate shorted components and follow control signals through the startup and charging circuits.
