Hi, my brand new Asus ultrabook was installing updates, got to 30-40% and the screen turned off. I waited for about 30-40 mins but nothing changed so i turned it off from the button. Tried holding it down several times, and turning it back on and off but nothing changed. I can hear it loads windows and i have blindly managed to type my password and i've even heard skype load so it must be working properlu besides the dark monitor. Please help out!
