ASUS A7Sv notebook motherboard schematic, a sizeable 7.56 MB PDF. The name gives the model but no PCB revision, so compare the revision silkscreened on the board with the title block before trusting part values.

Open it in any PDF reader; searching for net names helps follow signals across the many sheets.
