My son has an Asus K55N laptop. It is only about 1 year old. It has Windows 8 on it. It has been working fine until the other day. When you push in the power button, the light on the power button and 3 lights on the front of the laptop come on for about a second and then go back off. Nothing appears on the screen. I have already tried removing the battery and unplugging it and then holding the power button in for a minute and then putting everything back in and turning it on. This did not work. I will also mention that it behaves the same with the battery in it as it does without the battery in it. I even took both memory sticks out and re-seated them but that did not work.
I am guessing it is something with the motherboard but I am not sure. I checked both small ribbon connections going to the motherboard and they are tight. Any suggestions??
