Dell Latitude 5520 Bios Password unlock

[Markus1741]

Hi ,

I have a problem with Latitude 5520. Laptop have bios pass.
I cannot read xmc 25rh256c with my programmer TL866-II plus. When I try to read this soic, only uncheck id possible but the bios is corrupt.
Because I write the backup to Winbond w25q256 I get 3 amber 6 white error.
Bios at post 393 above is working, but after a few start laptop isnt boot. 3 amber 6 white led blinking.
when I check the backup with MeAnalyzer I see the ME is not corporate but consumer. This is a business laptop.
Someone can check and fix this backup?

Latitude 5520
i5 11th gen
Svctag : 7TBG5B3

Hello all, my name is Ryan and i was wondering if anyone can help me remove the admin password (BIOS) on my dell latitude 5520? Dell Latitude 5520 11th gen i5, with my service tag 6NF6NL3-8FC8 Express Service Code 14476920807
I purchased it over two months ago second hand but never looked into the bios until recently. Functions normal without hiccups but I'd like to change some features within the Bios but an admin lock requiring password is preventing me from doing so. Any help would be greatly appreciated..

you have to post your bios dump, without it can't be done.

Thank you. That worked, though I was still getting the same error until I completely wiped off the ssd drive and reinstalled Windows from scratch.
