Schematic set for the ASUS K40AA laptop at board revision 1.2, compressed into a 1.22 MB RAR archive. It documents the circuit of the mainboard, including power rails, enable signals and connections between major chips. Use it to follow the power-on sequence, find which rail is missing and read the values of resistors, capacitors and MOSFETs when replacing parts. Extract the document and open it in a PDF reader or the format provided. Confirm the board is marked R1.2, since other K40 revisions may use different circuitry.
