Samsung R420 laptop schematic for mainboard BA41-01581A, delivered as an 880 KB PDF. Samsung uses the BA41 prefix for its own motherboard part numbers, so this follows the in-house numbering rather than an external ODM pattern. The document is useful for tracing the power-on sequence, checking charger and battery circuitry, locating test points and isolating shorts on the main rails. Before using it, read the BA41 number and any revision suffix printed on the PCB, because Samsung boards of one model may come in several versions.
