Samsung R510 notebook schematic based on the board code-named LYON, marked as an internal document at revision 1.0, in a 4.83 MB PDF. The project name and revision help match it to the right mainboard, since Samsung often prints these on the PCB. Use it to trace power rails, follow the power-up sequence, and locate the parts on a shorted circuit or missing voltage. Readable in any PDF viewer; confirm the board shows LYON and revision 1.0 before trusting part values.
