RAR archive of 1.40 MB named after board number DA0Z8BMB6C0, which follows the Quanta DA-prefix scheme for project Z8B. The name gives no laptop brand or content type, so extract it to see whether it holds a schematic, boardview or firmware. Note that the name appears to contain a Cyrillic C character, which can break searches for the number. Use whatever it contains to trace power rails and locate components, after confirming the board marking matches.
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.
