Hello everybody; I have a question, the chip: "winbond 25q80dvsig" is the BIOS chip for this computer, right? If it is I can just dump the BIOS unto a file and upload it here for assistance to remove the password, right?

[Vesko356]

No, it's not the bios chip.

Hi guys
I have latitude 7400 with a bios password

Can I upload the BIOS only through the programmer? Or can I do it through Windows?
please don't laugh loudly)

[Vesko356]

You must use a programmer to read the bios chip. No other easy/lazy way.
