    I had the issue where my xps m1530 with LED LCD screen would boot fine on AC power but on the battery it would boot but with no back light on the screen. weather you were going just into your BIOS or Windows. You could here windows boot fine (could here the startup sounds) and if I put a flashlight on the screen there was an image. but no back light.. anyways I got a new battery and everything is fine now.. turns out the battery has a separate contact connection for the back light.. and my battery was defective. I knew it was the battery since it would run my back light if it was warm or I warmed the battery up... dell sent me a new battery been using it for a few weeks now with no issue..

    Also after my laptop was on for more then 4 min running on the AC and I went the the battery it was fine. It was just when the battery had not been used for more then 5 hours or more I would have the problem.
