Embedded controller firmware labelled lotus-14r, a compact 37.6 KB ZIP. No brand is given, though Lotus is known as a Samsung board platform name; confirm against your PCB. EC firmware manages power sequencing, battery charging, keyboard and fan control, so a corrupted EC can cause no-power or charging faults. It is programmed into the EC or its dedicated flash, depending on board design, using a suitable programmer. Read and save the existing EC contents before writing, and verify the chip type and image size.
