BIOS and keyboard EC firmware set for the Acer Aspire A514-52K, board marked NB8517_MB_V2. Including KBEC means the archive carries both the system BIOS and the embedded controller code, useful when a board shows no power or charging faults after a bad EC flash. Write each image to its proper chip with a programmer, after making a backup of what is currently on the board. Also confirm that the V2 marking on the PCB matches.
