Samsung Q35 laptop schematic, distributed as a 1.68 MB PDF. Beyond the model, the name gives no mainboard code, revision or platform code name, so confirm the version by comparing the title block with the board. The pages document power sequencing, regulator circuits, connector pinouts and signal routing between the chipset, memory and peripherals, which is what you need to diagnose no-power, no-display or charging faults. Open it in any PDF viewer and use text search for nets and designators.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
