Firmware file for the Lenovo IdeaPad S400, built on motherboard LA-8951P. LA-xxxxP board numbers are a Compal pattern, so the board was designed by Compal for Lenovo. The 3.29 MB archive contains an SPI flash image for recovering a board that is dead or stuck due to corrupted BIOS. Several S400 dumps exist for this board, so compare them before choosing. Check the PCB marking, back up the original chip with your programmer, and confirm the extracted size matches the flash chip.
