BIOS for the Lenovo IdeaPad 500-15ACZ on board LA-C285P, supplied as a 2.43 MB RAR. The LA- prefix is Compal's numbering scheme, as Compal manufactures this board for Lenovo. No revision or EC details appear in the name, so check the PCB label before use. The dump is used to recover a laptop that powers on with no display or after a failed BIOS update, via an SPI programmer. Save the original chip contents and confirm the image size matches the chip capacity.
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 @biosarchive. Enginerys does not host this file.
