Dell Latitude 5520 - dump bios to obtain password

[iwu]

Hello,

I am not experienced in electronics, but I really want to check if my idea is possible.

I have motherboard replaced from Dell Latitude 5520 (11th gen on i5 CPU).
BIOS/UEFI access on that MB/PC is blocked by password which I want to get it know - even if I need some bruteforcing or stupid manual activities.
There was no computrace activated.

I was happy when I saw many posts about removing BIOS password based on .bin file dummps. I wanted to go little further - get to know the password from the dump.

1. I do not know how thebios chip is identified and I would ask you if my assumption is good or wrong:

U2502 on PCB >> 8-pin winbond chip 25r256jven 2105 6103 moo14 marked on photos.

8-pin winbond chip 25r256jven 2105 6103 moo14

located:


I have created some photos if needed. So the back side of the MB is also attached. If you need more picz please let me know.




btw I'd tried google and after that I am less sure and aware.

Post your request inside the dedicated bios forum. See above.

Thank you for your reply. I have posted https://www.badcaps.net/forum/troubl...admin-password hoping that it will be somehow connected with schematic
