Dell xps 15 9520 not turning on

I bought a dell xps 15 5 weeks ago for university. So far everything went smoothly, but after closing the lid yesterday and after 2 minutes opening it again it doesn't turn on anymore. I have left the laptop to charge a whole night at it still doesn't turn on. The only sign that my laptop is still somewhat alive is that when i plug in the charger the little white balk turns on and then turns of again as an indication that the battery is already full. Is there anything i can do to fix this? I need my laptop to be working as fast as possible for my study.
