Samsung NP-R428 and NP-P428 service archive for the Suzhou-UL-DDR3 platform, listing boards BA41-01212A, BA41-01213A and BA41-01214A, in a 927 KB RAR. The BA41- prefix is Samsung's own PCB numbering, and the three numbers likely cover different sub-boards or variants of the design. The name does not state exact contents, so open it to check whether it holds a schematic, boardview or both. Match the BA41 number on your board to the correct sheet before tracing rails or components.
