I told a friend I would look at his Dell Latitude 600 but I have no clue on how to fix it (told him I didn't but that I would try). When you hit the power button the lights flicker and then turn off and the screen never comes up. So it seems to be a power issue. However the battery on this laptop has a button that will light up lights to tell you if theres power. Once hit the light shows all lights which I assume means its powered, and I've tried using the power adapter. So does anyone know how to fix this problem or at least have a idea on what it could be?
