Service schematic for the ASUS X505BP laptop mainboard, revision 2.0, supplied as a 5.74 MB PDF. ASUS usually names boards after the model with a revision number printed on the PCB, so check that the board reads X505BP and REV 2.0 before using component values. The diagrams help with tracing power rails from the adapter, checking the charger and regulator outputs, and locating the BIOS flash and EC when a unit will not power on. Any standard PDF viewer can open it.
