Dell Latitude 5420 Bios Password 8FC8

[Sley]

Hello everyone,

I'm currently working on a Dell Latitude 5420 that is locked with a BIOS password.

I've identified two different Winbond chips on the motherboard (see attached photos):

• A Winbond W25Q256JV
• A Winbond W25Q80DVSIG

Before proceeding with a BIOS dump and flash, I want to be sure:

Which of these two chips actually stores the BIOS password?

Thanks a lot for your help!

We can only help if you post your bios backups. Do you have an SPI programmer ?

Hello,
My Dell Latitude 5420 is stuck on the Dell Security Manager message at startup. I can't do anything.
Here is my BIOS.
If someone could remove my BIOS password so I can reflash it later, please.
It's an 8FC8.
ST/SN: 17CHBY3.
Thanks.

Where ?
