    he situation is the same as with the BIOS from this topic. The laptop responds to the power button, the indicator on the button lights up, but the screen is black. The power button lights up for about a minute, then turns off. In this case, the fan makes a couple of revolutions both when turned on and off. I think the problem is most likely somewhere in the diet. The LED indicator on the front of the laptop does not light up.

    Hello everybody. Help with BIOS on Dell Latitude 5420 LA-K491P rev3. Stopped turning on after reboot. I think it was updated incorrectly. I downloaded the BIOS from this topic, the behavior of the laptop changed. When I press the button, the LED lights up, but the screen is black.
    Here is my corrupted BIOS and laptop data

    He is already lost. It was not read correctly at first. I noticed this after I backed up the file and saw that it was small in size. I don't have the original. I put another dump right now. The computer works, but there is an administrator bios password. No changes can be made. Can it be fixed? Windows loads and runs normally!
