Thank you for your quick reply, onnizbox.

I can enter BIOS settings but I can't change Admin or System passwords. Is there something I am missing?

Enter any wrong password three times, post the new code...
Restart the laptop and enter the new password that I will calculate.

Thank you, onizzbox

I just saved changes, restarted without turning off and pressed F2 to enter again BIOS settings and this time allowed to change everything. Maybe this helps others.
