Schematic in PDF form, 21.2 MB, covering the ASUS X415JA and referencing the X415EA as well, two related platforms sharing the same chassis design. The large file size suggests a full multi-page diagram set. Technicians rely on such a document to follow power-on sequencing, check the charging circuit, trace a short on a main rail, or find the correct value of a missing component. Verify that the board revision silkscreened on your PCB corresponds to the drawing before replacing parts based on it.
