Circuit diagram in PDF for the Olympus platform, board 07258-1, PCB part number 48.4Y603.0SA, about 1.37 MB. Numbers in this 0xxxx-x and 48.4 format belong to Wistron, the ODM that designs and manufactures boards for several notebook brands. A technician reads it to follow the power tree, locate where a rail is generated, check enable and power-good signals and identify parts by reference designator. The -1 suffix denotes an earlier revision than the -3 sheet, so match it with the number printed on the PCB before trusting values.
