Revision 2.0 circuit diagram for the ASUS K42F notebook motherboard, in PDF format at about 1.45 MB. It sits between the Rev 1.0 and Rev 3.2 documents of the same model, so matching the board revision matters when choosing which one to follow. Use it to read the power sequence, find the charger and system regulator circuits, check net names around the EC and confirm part values on a damaged section. A standard PDF viewer with text search makes locating reference designators and net labels quick.
