This code changes if i enter wrong password 3 times and reboot the laptop. Changes every time i turn on the laptop after 3 wrong attempts.
When I try with this calculator says Fujitsu Siemens:

Well, then the only chance might be to read the BIOS and EC firmware (they must be both serial flashes) and email them to me to have a look.
You will need a serial flash programmer.

Is this doable??
Do you know what kind of EEPROM is this laptop using.
If i read the content from the chip can i find the password
Can i read the chip whit pick kit2 clone and adapter for 25cxx / 24cxx / 93cxx??
Can i destroy the laptop? |

I finally found the time to open my laptop.
I found 25q80bvsig Winbond Serial Flash Memory is this chip for the bios passwor.
Or to search other chip, another memory I could not find. |
