BIOS and EC package for the Lenovo ThinkPad Edge E440, built on board NM-A151 revision 1.0, compressed in a 4.84 MB RAR. The name mentions the ITE IT8586E embedded controller, suggesting the archive also holds EC firmware alongside the system BIOS. Technicians use these images to repair no-power or no-boot faults by reprogramming the SPI flash with a programmer. NM-A numbering is Compal style used on many Lenovo boards; confirm the number on the PCB matches and back up the chip first.
