Archive for the Lenovo B450, 784 KB in RAR format, with the tag LA 14 in its name; the meaning of that tag is not certain, possibly a project or board code. Contents are not listed, so unpack with 7-Zip or WinRAR to see whether it is a schematic or other service material. Diagrams like these are used to trace power rails and signals, locate components and narrow down a short. Compare any board code inside with the marking on the B450 mainboard before relying on it.
