Embedded controller firmware called simply EC, compressed into a 57.4 KB ZIP, with no laptop model, brand or board number in the name. The EC manages power-on sequencing, charging, the keyboard and fans, and corrupt EC code often leaves a board dead or unable to charge. Because the target device is unknown, this file should only be used once its origin has been confirmed. Identify the EC chip on the board, read out its current contents as a backup and compare sizes before programming anything.
