You need to enable it in the BIOS setting. It's disabled by default.
Thanks ganboing, I dunno why it shouldn't be on by default (like the HDD Light selection box), but I've got in on now.

Thank you for contacting the Intel Communities.
This behavior after the BIOS update to the version 0036 is known and possibly it could be fixed in future BIOS releases.
The fix would be to access the BIOS and enable the option as advise by ganboing.
