Schematic for the ASUS K53SV laptop mainboard as a 593 KB PDF; the name gives no board revision, so compare the revision printed on your PCB with the one in the title block. The K53SV is a notebook with discrete NVIDIA graphics, so expect GPU and VRAM pages alongside the power circuitry. Open it in any PDF reader and search by net name or reference designator to trace power rails, find the source of a short, check charger and regulator circuits and follow signals between chips.
