With ABM off and brightness at the minimum (0), the screen is on but low brightness. If you set ABM to 4 and then maximize a black terminal window, the screen will for all intents and purposes turn itself off. When going back to a bright screen it will turn on again. By on and off here I don't mean actually off, but the brightness is almost not visible.
I am using a Lenovo A485
