Asus laptop wont turn on (no display and sound). I was just playing then suddenly it hanged. Then I shut it down by holding the power button and when it was off, I tried to turn it on again but it didn't. No display and no sound from the hard drive. No hard drive led even, only power and battery led. I tried taking out the ram (I have 4+4gb, took out the extra 4) but it still did not work. The battery is not removable. Please help me. My laptop is an Asus x556uqk
