Motherboard schematic for the UX31A2 board, packed as a RAR archive of about 1 MB that holds the diagram in PDF form. The mb_r20 token in the name points to main board revision 2.0, so compare it with the revision silkscreened on your PCB before trusting net names or part references. Once extracted, any PDF reader opens it, and the text search is handy for following power rails, enable signals and charger circuitry while hunting a short or a missing voltage around the board.
