Samsung laptop motherboard package for board BA41-02206A, supplied as a 6.54 MB ZIP archive. The name does not list the contents, but archives of this size usually hold a schematic and sometimes a boardview. BA41 numbers are Samsung's own main-board part codes, so the number on the PCB silkscreen or label should match before you trust any rail or connector reference. Use it to trace power rails, follow the standby and charging circuits, and locate test points while hunting a short or a missing voltage.
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 @ITHINKHS. Enginerys does not host this file.
