Embedded controller firmware for a Dell laptop on Wistron board 10272-1, a 256 KB image. The EC handles power sequencing, charging, keyboard and fan control, so a corrupt EC chip often causes no-power or no-charge faults. Wistron identifies its boards with a five-digit number and dash suffix like this one. The model is not named, so match the 10272-1 marking on the PCB. Read and save the original EC chip contents with a programmer before writing, and keep it paired with the matching BIOS dump for this board.
