Schematic documentation for the Compal LA-1521 board, revision R1.0A, inside an 812 KB RAR archive. The trailing letter marks a minor update to the 1.0 design, so the exact revision on the motherboard should agree with the drawings before values are trusted. LA- numbers are the board codes of Compal, an ODM whose notebook boards appear under several laptop brands. Once extracted, the diagrams are used to follow power rails and signal paths, identify components by reference designator and work out which circuit is pulling a line to ground.
