Schematic for Wistron board 203013-1, delivered as a PDF inside a 3.79 MB RAR archive, with no laptop model named. The same board number appears on Lenovo Flex 5 14ITL05 machines in other files, but match the number printed on your PCB rather than assuming. Extract it and open it in any PDF reader to trace power rails, follow the power-on sequence, locate charger and VRM components, and identify the parts feeding a shorted rail. Wistron schematics usually include a power-rail diagram near the front.
