Schematic set for the Dell 14-3478 notebook, drawn for Wistron mainboard 17841-1. Wistron uses this five-digit-plus-suffix board numbering on many Dell designs, so the ODM name often appears on the PCB rather than Dell. At 5.70 MB this PDF opens in any standard reader and serves for diagnosing no-power or no-boot faults, measuring rails against expected voltages, locating components and checking pull-ups on key signals. Compare the board number and revision on the PCB with the drawing before relying on values.
