My laptop won't power on

Hello friends...!! I was watching this movie series in my dell laptop late last night before I fell asleep leaving the movie still playing until the laptop went off when the battery was drained (I assume! since I was asleep). Anyways, I woke up and found the laptop off so i plugged in my power adapter and switched on the laptop.
Well, I could hear the movie starting to play in the background but before I could log in the power in the house went off and so i decided to switch the laptop off and then closed it.
The problem now is that when the power in the house came back (after almost 6 hrs) I plugged in my power adapter and tried to switch on my laptop but it did not power on.
I then checked the output of my power adapter (since I do electronics) and found it to be perfectly fine. What bothers me is that when I plug in the adapter not even a single "indicating LED light" goes on. Its as if no power is going in at all!
I was already in the mid of preparing my field report using this laptop and time is not in my favor.
PLEASE HELP...
