Dell Latitude 5520 Bios Password unlock

[farouk_1994]

Would this be the same as the one from the dell website using the service tag?
My laptop locks immediately after power up, I can't even get to the bios menu using F2

you need to upload your dump file extracted from the bios chip you can see how to do it on youtube

Backup bios ( not Winbond 25Q80DVNIC ) , Find chip 64 , 128 , 256 ...and service tag.

You're totally right! I read about that the bios chip needs to be like 2,4,8,16,32,etc. But I did not understand and could not find it. I now understand what it means (sorry, my English is bad).
The chip is "GD25R256D". But anyone tried this to attach with a clip? I want to flash with CH341A with clips, but the attachment looks really small. (I did not remove the whole motherboard yet, but if it is not necessary I don't need to). I attached picture of the chip. Anyone tried with the clip?

you may need a pogo pin connector

as per your chip you need ( WSON8 (8*6mm) )

Buy a programmer (eg: CH341A) and read your bios chip and post it here.
