Catalogued as a schematic, this 67.2 KB PDF has the short name 45L-D and no laptop model, brand or board number. The code is too brief to identify reliably; it may refer to a component series or a variant of the 45L document filed alongside it. Open it in a PDF viewer and read the heading to establish what it covers. Whatever the content, match the part marking or board label on your hardware with the document before taking pinouts or values from 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 @cyberlanelectonik. Enginerys does not host this file.
