Schematic for the Samsung NP-M70 notebook in a 4.24 MB PDF. The name states only the model, with no board code name or revision, so the drawing should be checked against the motherboard markings before trusting component values. A diagram like this shows how each power rail is generated and where it goes, helping a technician locate a short, measure voltages at the right points and trace video, audio or USB signals. Open it in any PDF viewer and use search to jump between nets and part references.
