Asus G51vx laptop won't boot

Hello, I bought an Asus G51vx at newegg.ca recently. I've been using it for one week without any problem. But yesterday, it suddenly wouldnt boot up. I pressed the power button and some lights flashed and nothing happened(no noise, HDD activity, nothing). I pressed the button again and the light didnt even flashed. There was no charge light neither even with AC plugged in. So i looked on google and read this post:

Tried everything they said but only got some light to light up for a second and then turn off. Im using windows 7 64 bits, if that matters.
Anyone can help please?? Thanks in advance
