NP-Q70 PCB diagram with the unexplained suffix imp, a 1.2 MB schematic PDF identical in size to the plain NP-Q70 file and likely a duplicate. The NP model prefix matches Samsung notebook naming. Use it to follow supply rails, check the charger and system regulators, locate parts on a shorted line and verify connector pinouts during board-level repair. Neither board number nor revision is stated in the name, so compare the title block with the markings on your PCB before relying on values.
