Dell XPS 1530 won't power up suddenly after updates from Dell

I replaced the screen on my Dell XPS m1530 today. It powered up, I checked it out and then proceeded to allow the 'automatic updates'.



Suddenly, it powered down and now I can't get it to start at all. Occasionally, I get a glimmer of the blue led behind the power button when it is pushed but the laptop will NOT power up.



Any thoughts?



I had it working then it died after the software updates...so the screen install was successful....



How do I get it back?



Thanks
