BIOS and embedded controller firmware for the ThinkPad X260, LCFC board NM-A531 revision 3.0, supplied in a ZIP. Having both images lets a technician restore the main BIOS flash and the EC, useful when the laptop is dead, will not charge, or shows power button faults after corruption. Program each image to the correct chip with a suitable programmer, confirming the chip type first. Verify revision 3.0 on the board and save backups of the original chips before writing anything new.
