I checked the hibernate situation and it was turned off. So, I attached another monitor and it also went black. I then restarted and pressed f-8 to find that it came up in dos ok... I deduced it could either be an overheat problem or a program problem. Either way there was a problem with the video card. I shut down the laptop, took out the battery, removed both 1 gb rams, exchanged positions, plugged in a/c power, and restarted. still black. I then removed one card, restarted, still black. I then exchanged them, and restarted...and it worked. I then double checked to make sure it wasn't just the card slot (it wasn't) One card doesn't work at all. I will purchase another 1 gb simm asap. Problem solved!!!!!!!!!!!!!!!! Pass this one on!!!!!!!
