Dell Latitude 5400 Bios password

[izaak94]

Now I see that it is incomplete, my problem is that I have already erased the chip and I will not be able to make a backup copy again, will there be a solution?

your bios dump is corrupted, Bios region has no volumes, read again bios 2-3 times and compare results, if they are the same then you have a good dump.

It only turns on and off, can't provide video.

Re: Dell Latitude 5400 Bios password

I do not have a way to post the bios. No programmer or anything. Is there anything else I can try?

Re: Dell Latitude 5400 Bios password

How do i do that? I cannot get into the bios at all. It is locked behind the Dell security manager password. Shows a black screen and a place for password. Says something along the line of this system 2zl90x2-001 is locked. yadda yadda
