Datasheet-style PDF named 30BQ100, 102 KB, catalogued under schematics. The name carries just a semiconductor part number and no information about a laptop, board or revision. Such documents describe pin functions, voltage and current limits and the footprint of a component, which is what matters when replacing a burnt or shorted diode near a power input. Open it in any PDF viewer and double-check the code printed on the part, because similar markings can belong to parts with different ratings.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
