EC firmware for the Packard Bell TE69BM notebook, an Acer group brand, on Compal board LA-A621P revision 1.0. The 128 KB binary is for the embedded controller that handles power on, battery charging, keyboard and fan control. A corrupted EC image can cause no power or no charge symptoms. LA-numbered boards come from Compal. Read and keep the existing EC contents before writing, confirm the revision on the PCB, and use the matching BIOS dump for the same board when restoring the main flash.
