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 ?

Need help... BIOS is not locked, system starts and perfectly works from USB but device hangs during POST if any SSD presents in its M.2 slot inside the case instead of connecting via USB3 and USB-M2 adapter as I have to work for now.

This issue has appeared after macOS update (yes, a third system on it is Hackintosh).

First time I've got this problem after same action - the seller simply changed a whole device by warranty. I've thought it was a hardware problem with SATA controller. So now I think that system updater rewrote some UEFI areas - CMOS battery removing didn't help. BIOS update program fails with unknown error (code 999 IIRC).

Model CF-20G5-05VM as printed on label (or CF-20G5108VM / CF-VEK206LM as shown in BIOS setup)
Serial 9FKKC22343 as printed (2nd serial in BIOS setup after slash is 9FKKC22328)
