Quanta motherboard DA0X9QMB8D0, revision D, packed in a 23.4 MB RAR archive. Quanta numbers boards with the DA0 prefix followed by the project code, here X9Q, and the revision letter. The archive size suggests multiple files, such as schematic, boardview or BIOS, though the name does not say. No laptop brand is given, as Quanta builds for several makers. Check the DA0X9QMB8D0 marking and rev D on the PCB 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 @ShareMan_Electronic_Files. Enginerys does not host this file.
