Schematic diagram in PDF for the ASUS Chromebook C423NA, board revision 1.2, packed into a 1.23 MB RAR. A technician uses it to follow power rails, the charging circuit and enable signals, find component values and debug no-power or no-boot faults. Open the PDF with any reader and search by net or part reference. Compare the revision printed on your mainboard with 1.2, as component placement and values can change between revisions.
