Schematic for the ASUS Chromebook C423NA at revision 1.2, supplied as a PDF inside a 1.23 MB RAR archive. Once extracted it opens in any PDF reader and can be used to follow power rails, the charging circuit and the embedded controller, and to identify components on a dead or no-charge unit. Chromebooks rely on their own firmware and EC behaviour, so the power-on sequence pages are especially useful. Check the revision printed on the motherboard against 1.2 before trusting part values or connector pinouts.
