Schematic diagram for the ASUS X540MA notebook mainboard at revision 2.0, a PDF stored inside a RAR archive. ASUS prints the model and revision on the board's silkscreen, and parts of the circuit can change between revisions, so verify REV 2.0 before relying on component values. The document is useful for tracing the charger and power rails, checking the power-up sequence, following USB, display and audio signals, and finding which component a dead rail comes from. Open it in any PDF reader after extraction; text search helps locate net names quickly.
