if your notebook powers down and doesn`t show that something is still "on" and consuming power - i`d call that "broken by design".
it should not be up to the operating system to make sure that all parts of the hardware are switched to off.
if i power down some device and there is nothing showing "hey, here is something active" (e.g. by some led or lcd) - i expect it to stop consuming power.
maybe it`s not that broken as my PC, which is consuming 20W after power-off (due to power-supply) - but i really would go ask the vendor and first complain there.
they should know the details.

Yes, you are right!
I don't know why, but as commented in Bug #10797, if I close my LCD
Display (activing LID), power on again (because when LID is actived, my
laptop hibernate), and shutdown, my battery charge not is changed.

You must be triggering some combination of ACPI events that happen to do
the right thing on the system. However if issueing a power off doesn't
turn off the system, then it really sounds broken.
