BIOS and EC firmware package for the Dell Inspiron 15-5510, with Wistron board number 213109-1, archived as an 11.0 MB RAR. Wistron uses six-digit numbers with a dash suffix like this for its Dell designs. Including the embedded controller firmware helps when the laptop has power-on, charging or keyboard faults caused by a corrupted EC chip. Flash each image to its matching chip with a programmer, confirm the board number on the PCB, and back up both original chips before writing.
