Firmware dump for the Lenovo IdeaPad G580 laptop on Compal board LA-7988P, supplied as a 2.99 MB RAR archive. LA-xxxxP codes are the Compal motherboard numbering, and the same board can appear under several Lenovo models, so the code on the PCB is what matters. Technicians use such an image to reflash the SPI BIOS chip when the machine powers on without display or after a bad update. Extract the archive, compare the file size with the flash chip capacity, and save a backup of the original chip before writing with a programmer.
