Schematic diagram for the ASUS K40AA, revision 1.2, stored as a 1.28 MB PDF. The sheets let a technician follow each power rail from the adapter input through the regulators, trace signals and look up part values for replacement. It is useful when isolating shorts, missing voltages or a failed power sequence. Open it in any PDF reader. Note that K40 variants with different suffixes use different boards, so confirm the model and the R1.2 revision on the PCB before relying on it.
