Original embedded controller firmware read from a machine labelled u410, likely the Lenovo IdeaSlim U410, though the brand is not stated; the file is 512 KB and org marks an unmodified dump. The EC manages power sequencing, charging, fan control and the keyboard, so restoring it can fix no power or charging faults. Flash it with a programmer to the EC flash chip after backing up the existing contents. Compare the board number printed on the PCB with the source unit and confirm the memory size, since EC images are board-specific.
