Hi new here. Got a new computer over the holidays. Everything was working great for about a week. Then I couldn't change my brightness anymore.

1) The FN key does nothing with the brightness. It works for sound controls and other shortcuts but not brightness.
2) Trying to change the brightness through control panel or power options does nothing.
3) Reverting to a different driver does nothing.

Dunno what else to try. Someone help.

Laptop - Aspire V15

Display Drives - Intel HD Graphics 4600 and NVIDIA Genforce GTX 860M
