Schematic in PDF form for Compal motherboard LA-7121P at revision 0.2, compressed into a 1.05 MB RAR. Compal's LA-xxxxP numbering marks boards it builds for several notebook brands; this number also appears on the Acer Aspire 3830TG. Use the diagram to follow power sequencing, check rail voltages, read signal names and identify component values. Because 0.2 is an early revision, some parts or nets may differ from a production board, so compare against the revision printed on your PCB.
