ASUS schematic in PDF for the UX550GD and UX550GE, revision 2.1. At 8.40 MB it covers the full board, letting a technician trace power rails, check the charging and VRM circuits, follow GPU and CPU power paths, and find the source of shorts. It opens in any PDF reader. Confirm that the PCB reads revision 2.1 and matches your exact model variant, as the GD and GE share a design but may differ in parts.
