PDF schematic for the Lenovo ThinkPad X1 Carbon LRV-1 board, listing Wistron numbers 14282-2M and 14282-3. Wistron builds this motherboard, and its five-digit board codes are what appear on the PCB rather than the Lenovo model name. The document shows the charger circuit, system power rails, EC connections and the startup sequence, which a technician follows to find why a laptop does not power on. Open it in any PDF reader, search by net name, and confirm your board number matches one of the two listed.
