EC firmware image for the Lenovo Yoga 11e, board code LLA-1 with Wistron-style board number 17833-1M, in an 8.00 MB binary. The embedded controller handles power sequencing, charging, keyboard and fan control, so a corrupted EC often shows up as no power-on or a dead battery charge. Wistron uses five-digit numbers with a revision suffix like this one. Match the number printed on the PCB, dump the original chip with a programmer first, and make sure the target flash is 64 Mbit so the image fits.
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 @biosfilebins. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
