I have an ASUS K55A Laptop. I was watching a video on YouTube and i literally walked out of my room and back in and the full laptop was blank. No sign of power or charging. Seen loads of posts about how taking the battery out for a certain amount of seconds and pressing power would work. Tried all the various ways several many times. Still no avail. What is the problem? It was working fine and I bet its a simple solution:( P.S. After trying the battery trick and pressing the power button it the light flickers for a second then goes off again..
