i havent used this computer in a long time but a few weeks ago when i got a MBP i took it out of my closet to transfer some stuff over. when i put this computer away it was in fine working order, but now whenever i try to turn it off the light on the power button stays on and the fan in the back is still going, but the computer is not functionable at all at this point, the screen is just black. im guessing its something to do with the power supply but i figured id ask all you long term mac users.
