EC firmware archive for a laptop main board numbered 13251-1, with the LSZ-1 project code also in the name and MEC indicating a Microchip MEC-series embedded controller. The 13251-1 numbering follows the Wistron ODM pattern. The 110 KB ZIP should hold the controller image used to restore power-on, keyboard, battery or fan behaviour after EC corruption. Back up the existing EC content before writing, confirm the board number on the PCB is 13251-1, and use a programmer or tool that supports the MEC chip.
