Lenovo Yoga 13 firmware package in RAR format holding both the BIOS image and the EC (embedded controller) firmware, 3.12 MB in total. Having the EC code alongside the system BIOS matters when a laptop will not power on, charge or respond to the keyboard, since a corrupted EC can mimic a dead board. The name gives no board number or version, so compare chip sizes and markings against the images inside. Always dump and keep the original contents of each chip before reprogramming with an SPI programmer.
