Firmware package for the Lenovo ACLU9 / ACLU0 design, motherboard NM-A311 revision 1.0, with the name pointing to an ITE IT8586 embedded controller. NM-A311 follows the LCFC numbering used for Lenovo G50-series boards. The archive is likely to contain the BIOS image and possibly EC firmware for the IT8586, which handles power-on, charging and the keyboard. Check the revision on the PCB, back up the original SPI chip with a programmer, and confirm the dump size matches the flash before writing.
