Lenovo IdeaPad S510p BIOS firmware for the LS41P mainboard, board number 12293-1, a numbering pattern used by Wistron, the ODM that built this board. The 3.26 MB RAR most likely contains the SPI flash image needed to revive a unit with corrupted firmware. Write it with an external programmer such as a CH341A or RT809H after reading and saving the original contents. Check that the board number silkscreened on the PCB matches 12293-1 and that the chip capacity agrees with the image size before flashing.
