Zip archive of 4.24 MB labelled with the Razer product code RZ09-01652, the numbering Razer uses for its Blade laptop models. The name gives no hint of what is inside, so the archive may hold a BIOS image, EC firmware or service files; open it and inspect the contents before use. If it contains a flash dump, compare the image size with the SPI chip on the board and save a full backup of the original chip with a programmer such as a CH341A before writing anything. Match the model code on the laptop label to this one as well.
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 @biositechyangiyer. Enginerys does not host this file.
