smbios-battery-ctl can't change settings when a admin password is set

[flyingflo]

Even with the --password option, the program returns sucessfully, but changes are not applied.
This is fedora 34 on a Dell XPS 13.

% sudo smbios-sys-info                                                                       :(

For example, I'm trying to set the charging mode to standard. It works if no password is set in the BIOS setup program.

% sudo smbios-battery-ctl --get-charging-cfg
Charging mode: primarily_ac

RAN CTYPES FUNCTION: token_obj_activate
LEAVE _errorOnNegativeFN --> 0

LEAVE activate --> 0

Charging mode has been set to: standard


% sudo smbios-battery-ctl --get-charging-cfg

For comparison, that's the trace without a password:

% sudo smbios-battery-ctl --get-charging-cfg
Charging mode: primarily_ac

% sudo smbios-battery-ctl --set-charging-mode=standard --trace
ENTER TokenTable()
ENTER __init__(<libsmbios_c.smbios_token._TokenTable object at 0x7f8255a4af40>, 1, )
ENTER _errorOnNullPtrFN(<libsmbios_c.smbios_token.LP__TokenTable object at 0x7f82559081c0>, <_FuncPtr object at 0x7f82559547c0>, (1,), )
RAN CTYPES FUNCTION: token_table_factory
LEAVE _errorOnNullPtrFN --> <libsmbios_c.smbios_token.LP__TokenTable object at 0x7f82559081c0>

LEAVE __init__ --> None

LEAVE TokenTable --> <libsmbios_c.smbios_token._TokenTable object at 0x7f8255a4af40>

ENTER __getitem__(<libsmbios_c.smbios_token._TokenTable object at 0x7f8255a4af40>, 838, )
LEAVE __getitem__ --> <libsmbios_c.Token ID 0x0346>

ENTER activate(<libsmbios_c.Token ID 0x0346>, )
ENTER _errorOnNegativeFN(0, <_FuncPtr object at 0x7f8255954dc0>, (<libsmbios_c.Token ID 0x0346>,), )
RAN CTYPES FUNCTION: token_obj_activate
LEAVE _errorOnNegativeFN --> 0

LEAVE activate --> 0

Charging mode has been set to: standard

% sudo smbios-battery-ctl --get-charging-cfg             
Charging mode: standard

The only diff is the addresses..

I wonder how I could help to resolve this issue?
Does anybody have an idea how to investigate this?
Found something interessting: Altough an admin password is set, smbios-passwd shows NOT installed:

smbios-passwd --info                 
User password
        Password stored as: ASCII
        Password MAX length: 32
        NOT installed

        NOT installed
Owner password
