Schematic for the LA48 project, board 11264-1, with an extra 4TD01 code that likely identifies a build or revision. The 11264-1 format matches Wistron's board numbering, pointing to Wistron as the designer. A second document for the same board exists elsewhere, so compare both when values or pages differ. In a PDF reader, technicians follow power sequencing, locate components and check shorted rails. Make sure the PCB markings, including any revision code, match before using it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @afsschematicfree. Enginerys does not host this file.
