Hello everyone, this problem has a solution. Basically you have to go to the "Power Option" (yes, right click on the battery icon), then "Choose what the power button does", and then select "Change Settings that are currently unavailable", then you can unmark or remove the "Turn on fast startup (recommended)" option. Reboot your system and you'll see the light.
The explanation is... when this option is marked, the system doesn't reload all the drivers (even the new ones), and even when you updated your video drivers, this options does not allow to load them again.
