Archive for an HP laptop motherboard numbered DAG7BFMB8D0, revision D, about 77.8 MB in a ZIP file. The DA... code follows Quanta's board numbering, so Quanta built this board for HP. The name does not list the contents, though the large size suggests several files, so extract it to see whether there are schematics, boardview files, firmware or photos. Whatever is inside, check that the board number and revision letter printed on your PCB match. If a firmware image is included, back up the original chip before flashing.
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 @azvoltagemap. Enginerys does not host this file.
