PDF schematic for the Lenovo ThinkPad E40 on the Quanta GC5B board, AMD platform with discrete graphics, compressed to 1.03 MB. Quanta project codes like GC5B appear on the PCB, so check the marking before use, since GC5 and GC5A variants differ. The diagram helps trace power rails, follow the EC power-on sequence, check GPU supplies and locate shorted components. Open it with any PDF reader, and pair it with a boardview for physical part locations.
