I have an Acer aspire v 15 touch, after the windows update, whenever I press Fn and the left button to decrease the brightness, what it does is increase and decrease at the same time then it lags a bit so I can't control the brightness. Same thing happens when I press Fn and the right button. I went to the device manager and the drive for the display is updated. What should I do?
