Schematic PDF for a laptop mainboard code-named Olympus, board number 07258-3 with the part number 48.4Y603.0SA. The 07258 numbering and 48.4xxxx.xxx PCB code follow the Wistron ODM pattern, so the board was built by Wistron for whichever brand sold the notebook. Use the diagram to trace power rails, check the power-on sequence, follow signals through connectors and read component values. The -3 suffix marks a specific revision; compare it with the label on your board, since the related -1 version differs.
