Circuit schematic for the Samsung NP-Q20 laptop, supplied as a 5.24 MB PDF. The name gives no board code name or revision, so compare the sheet titles and part references with the actual motherboard before relying on it. A technician uses such a diagram to work out power sequencing, find the source of a short on a rail, check voltages at regulator outputs and follow signal paths between the main chips. Any PDF viewer will open it, and the text search helps locate specific nets or designators quickly.
