[Olivier Robert <robby57@xxxxxxxxx>]

Charles,

Have you checked if the device is still listed in lscpi?
What is your battery state (power drain) before and after you switch it off?
IIRC, /proc/acpi/battery/BAT0/state or acpi -b should be helpful.

If it is really off, I'd expect the device not show up in lspci and your
battery state should show a lower value.

If you shut it off successfully, it is good news, as it means battery life
will be increased.

Keep us posted :)

Regards,
Olibob
