    It may have corrupted bios. anyone help? thanks.
    You can try this file, but I don't think you have a BIOS problem. Tip: a hardware error.​

    Yes its not easy at first,but now you know

    I'm hoping it's the last. But you are right, the laziness got the better of me. I just compared the previous fixed files and the original lock file with hex comparator. Is it really that easy? I was worried Dell went all Lenovo on us.

    I'll try it myself and see.

    Ok it took me a bit to grab the other BIOS images since one was an XMC chip. Now that I figured that out after searching, here they are.

    I have 3 of these Lattitude 5420 systems that I'm asking for help with. I will start with one for now and test it out first.

    Early thanks to whom helps out!!!

    Out of curiosity. If one unit has been wiped of the admin pw with the fixed BIOS file, can I use the same BIOS file from the first one on the other 2 since I have to re-enter the service tag anyway?
