    I can see the screen on the laptop but backlight is not turning on. I see a dim screen on laptop and when i presss any key on th ekeyboard it maskes noise.
    It`s not a bios problem, it`s hardware.

          EC dump request – Dell Latitude 5420, GDF40 LA-K491P Rev 3.0, MEC5107-LJ
          by mirjana
          Hello everyone,

          I need the EC firmware dump for Dell Latitude 5420, motherboard GDF40 LA-K491P Rev 3.0 (A02).

          The embedded controller is MEC5107-LJ (UE1).

          The EC flash chip is W25Q80DV, 8Mbit (1MB).

          I already have the 32MB BIOS dump (W25Q256JV), but my system is still not powering on — just amber blink. I suspect the EC firmware is missing or corrupted.

          If anyone has this board and can share their EC dump from the 25Q80DV, I’d be very grateful.

          Thank you in advance!...
