PDF schematic for the ASUS A7Sv notebook, a fairly detailed document at 7.56 MB. No board revision is stated in the name, so compare the revision silkscreened on the motherboard with the title block on the schematic pages. Technicians use it to work through the power-on sequence, check voltages at the CPU and graphics regulators, and look up component values around the charger and EC. Any PDF reader opens it, and using the text search on net names makes tracing a missing rail far quicker.
