my ibm thinkpad t30 has a white screen most of the time its completely white but sometimes its a dark greenish color when i hook up an external monitor it works fine and when i go to my monitors it shows the thinkpads screen as 8 bit color. im running windows xp.
Well since the external monitor works fine the problem can't be the video card. There could be a loose cable to the built in display inside. You've been helped by a 14 year old.
