PDF schematic labelled N76VM, an ASUS N76 series board designation, with an RG suffix whose meaning is not clear from the name. The diagram supports tracing power rails, the power-on sequence, charging and display signals, and checking component values during board-level repair. N76VM documents are often used as a close reference for related N76 boards, but confirm your board matches before relying on any part values or connections. Use a boardview to locate the parts physically.
