Small 1.63 MB zip holding BIOS firmware for the Lenovo B460e, with the mainboard named LB46E MB. The name lists no revision, flash capacity or version, so open the archive to see whether it contains one image or several. Technicians use such a dump to reprogram the board's SPI flash chip with an external programmer after a failed update or corruption. Before writing, read out and store the original contents, confirm the board identification on the PCB, and check that the image size matches the chip.
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 @bios_laptop. Enginerys does not host this file.
