Lenovo G450 archive of 1.40 MB. LA5751PR03 is likely Compal board LA-5751P at revision 0.3, and 1029A may be a date or build code, though neither is certain. The board number is not in the extracted data, so confirm it against the PCB silkscreen. A schematic is the most likely content. Use it to follow the power rails from the adapter input, check the voltages at test points, and identify the components around a short before replacing parts.
