Check if your user is member of the group "powerdev"

Or more generally:
Daemons with D-Bus interfaces on the D-Bus system bus can restrict who can 
call which of those functions.
To tell the D-Bus daemon about this restrictions, they install a policy file 
in /etc/dbus-1/system.d

In the example of powersave daemon, there is a file
/etc/dbus-1/system.d/powersave.conf

At the end it details what "desktop users" are allowed to do and it specifies 
that those users have to be in the group "powerdev"

Kevin
