Repair package for the Acer Aspire E1-471, a 2.8 MB zip whose name provides only the model. Nothing is said about the board number, revision or whether the archive holds firmware, a schematic or a boardview, so check its contents first. Firmware dumps are written to the mainboard SPI flash with an external programmer, and diagrams serve to locate components and test points. Confirm that the PCB board number matches, check image size against chip capacity, and back up the existing chip before writing.
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 @laptopbios21. Enginerys does not host this file.
