RAR archive for an Apple MacBook Pro main logic board, identified by the tokens FA255 and M42C, with MLB meaning main logic board. The name gives no A-model number, so confirm the board identity from the contents and the PCB markings. At 1.20 MB it most likely holds a schematic set. Technicians use such pages to trace power rails and signals, locate components and check suspect circuits; verify the 820- or 051- number on the board matches first.
