My Gateway Laptop dims & hums, off & on. The full brightness will come back to the screen & the hum will stop for a few seconds, then start again.

intermittent dimming could be a hardware issue... a failing/bad screen inverter. providing more info about the make and the specifics of the laptop, this a way to determine factors about the machine such as which type of illumination is used here.

it would say whether the laptop has bulb or LED... which would point to the inverter as being a possibility. the hum can at times be eliminated by adjusting the screen brightness higher.
