Good day everybody.
I have Dell Latitude E7450, which bios is locked with password. I've try few password generators with no success.
I read somewhere that password for this model is saved in additional IC - winbond 25X10CL.
When click 'unlock' in BIOS, there is a pop-up screen with System number code; 6NDG662-1F66. Create Dell bios cd, but can't boot from it /password protected :)/
I create a backup of bios and ec firmware and additional 25x10cl.
Also, is there any chance to change service tag?
Can someone help with unlock and/or service tag change?
Thanks.
Happy Easter!


EDIT: Password already removed. Try to figure out is it possible to change service tag..

You have win 25q64fv , erasing it and then write clear dump with out password viewtopic.php?f=41&t=7412&start=320 or viewtopic.php?f=41&t=55724

Hi, thanks. I've already clear the password. I would like to know is there any chance to change service tag.

First problem solved as I mentioned, service tag replacement - not successful for now. Return to customer in working condition.
