ZIP archive of 10.6 MB labelled for the ASUS X555LD laptop, revision 2.0 mainboard. The name does not reveal what is inside, so it may hold a schematic, boardview, BIOS dump or a combination of these service files. Extract and inspect the contents before use. For schematics and boardviews, the X555 family shares several board variants, so the revision printed near the board name on the PCB must match 2.0 before tracing rails or test points. Any BIOS image should be written only after backing up the original SPI chip.
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.
