Ok I really hope some one can help me here! I have an XPS M1730 laptop, that I bought a few months ago. I actually really like it, except for the fact that I can't run it on battery power alone (might as well be a desktop). The situation is, I turn it on and can see the very so nice Dell screen, and then the pretty Windows Vista loading bar scrolling across the screen, and then I can hear the (log in) sounds but can't see the log in screen. If I do manage to type in my password correctly, I get the start up sounds but no video display. Every thing works great as long as I have it plugged in. Help, I bought a laptop for portability!!
