Poweroff (halt) of the beaglebone

Hi,

When I use "halt" which my desktop PC, the kernel shutsdown
the system and powers it off.

When I do the same with my beaglebone, the system gets halted,
everything is still powered (beaglebone and its LCD7 cape).

I am using Robert Nelsons kernel with the PM-firmware blob.

is there any way to shutdonw/poweroff/halt the beaglebone so
that is really powers of (Backlight off, LEDs off, nearly
no power consumption) ?

Thank you very much in advance for any help!
Best regards,
mcc
