BBswitch can't turn ON nvidia graphics card

Hello, i installed arch on my laptop a couple of weeks ago. I want to use bumblebee and bbwswitch to maximize my battery life.
I followed the wiki: https://wiki.archlinux.org/index.php/Bumblebee but when it comes to use optirun i receive this error:

$ optirun glxgears -info
[ 1089.928944] [ERROR]Cannot access secondary GPU - error: Could not enable discrete graphics card

[ 1089.929039] [ERROR]Aborting because fallback start is disabled.

So i checked dmesg:

[ 1089.928447] bbswitch: enabling discrete graphics
[ 1089.928461] pci 0000:01:00.0: can't change power state from D3cold to D0 (config space inaccessible)

Any help please? Thank you.

Re: BBswitch can't turn ON nvidia graphics card

Thanks for your answer. Actually that wasn't the answer. I missed the point 6.16 on Bumblebee page, which explains that after kernel 4.8 bbswitch doesn't work and how to resolve it.
Thank you anyway!
