I have a Compaq Presario 700 Notebook (XP Pro OS) that was working fine yesterday and this morning NOTHING! No warnings--no error messages. When I hit the power-on button, the LCD lights up, but nothing else happens--no fan, no hard drive spinning, nothing on screen--no activity at all. If I plug the power cord in, the orange (power connected) LCD lights on the laptop and the separate laptop cooling board connected to the laptop's rear USB port comes on. So there is definitely power getting to the laptop. But I cannot open the CD drive--even when the LCD power light is lit. Does this mean the mother board is fried--or could it just be a bad fan? Help!
