    Dell Latitude 3500 i5 8th gen. wont turn on after EC change

    Dears,

    I bought this broken laptop. After turning on BIOS shows some message about problem with keyboard. After that boot normaly only works with delay. Idea was to update bios. During the update it stopped at updating EC round 75%, stopped charging and turn off. From this moment i was not able tu turn it on. When holding power button, orange LED is on, thats only reaction at all.

    I replaced MEC 1416 ( because i think thats why there was problem with keyboard and why it did not finish update) but same behavior. NO auto programming EC from bios just nothing. Reaction only on power button is orange led, when its pressed.
    No reaction on charger (USB C or normal). ESC+CTRL and power button also does not work.

    Now question is how to reprogram MEC 1416? I have only RT809F programmer.

    Thanks.

    According to the datasheet, section 1.1 and a quick review, this device will fetch the firmware from an external SPI flash device. Look around to locate this lower density flash device.
