Schematic in PDF, packed in RAR, for Wistron board 15139-1, project name adam_apl_4l, with the version or date code 1_0808a. The apl token likely refers to the Apollo Lake platform, and 4l to a four-layer PCB, but the name does not confirm either. The numbering follows Wistron's style, so the board was made by Wistron. Use the diagram to trace power rails, the power sequence and signals during board-level repair. Check the PCB number first.
