Re: Panasonic CF-20 Bios Password

for beep codes I use an app on my phone named Lenovo PC Diagnostic. try it, maybe you figure out what hardware problem is.

a single beep when forcing the shutdown, I think Lenovo Diag will not help me on this one.
It makes the same beep with a functional tablet

Hi my friends,

I have two same Panasonic CF-20E (mk2) asking password at boot.
- I unlocked the first one replacing by "0" in one of the 4 dump areas, it was a success.
- For the seconde one, it's not working. Booting OK but asking password. Even, deleting password_areas + ME_clean is not working, keep asking for password.

Can the password be stored in EC ?
