Schematic in PDF format for the ASUS Chromebook C423NA, revision 1.2, in a 1.23 MB RAR archive. A circuit diagram like this documents power rails, the power-on sequence, connector pinouts and component values, which helps when diagnosing no-power, no-charge or no-display faults. Open it in any PDF reader after extraction, ideally alongside a boardview for the same board. Check that the board revision printed on the PCB is 1.2, since part values and nets can change between revisions.
