BIOS and EC firmware for the Dell Latitude E6220, combined in a 4.96 MB RAR. Having both the system BIOS and the embedded controller image helps when the laptop shows no power, no POST or battery and charging faults. The name gives no board number or version, so unpack it to see the files and their sizes. Match each image to the correct chip on the board, save the original contents with an SPI programmer, and check the board number before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
