Archive for the Dell Inspiron 5447 touch-screen version, as the name indicates, stored as a 6.95 MB RAR file. The name does not specify whether it holds a BIOS dump, schematic or boardview, so list the contents before planning a repair. If it is firmware, flash it with an SPI programmer only after reading and saving the original chip contents. If it is board documentation, compare the board number silkscreened on your motherboard with the file, because Dell models often ship with several board revisions.
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 @hrtechno. Enginerys does not host this file.
