PCB diagram for the NP-R20 notebook, a 1.47 MB schematic PDF; the NP prefix reflects the model naming Samsung applies to its laptops. Board number and revision are not given in the name, so identify them from the title block inside. With these pages a technician can trace voltage rails, follow the power-on sequence, locate fuses, regulators and test points, and narrow down a shorted component. Always compare the project code and revision with the markings printed on the motherboard before relying on component values.
