Hi all:
I'm struggling with this problem and I'm not able to fix it. In order to get the maximum power saving I followed the instructions of this well known article:
https://wiki.freebsd.org/TuningPowerConsumption
But I can't turn off the nvidia chip. My laptop is a Thinkpad T420s with and integrated Intel card and a discrete Nvidia GF119M 4200. To turn it off I do (with acpi_call loaded):
This method was found by the turn_off_gpu.sh (https://people.freebsd.org/~xmj/turn_off_gpu.sh)
Neither previous command nor turn_off_gpu.sh script the Nvidia is turn off.

I read about a similar case in this thread:
https://forums.freebsd.org/threads/34240/
clod89 user said he only was able to turn off the Nvidia once.
Any idea what can be happening? What am I doing bad?
Thanks in advance,
Jes
