Hello, I bought a new Alienware m15x a year back and it has worked fine until last night. I was using it normally, and suddenly it powered off. I looked down and the indicator light on the power cable had turned off. (Usually it glows blue.) I unplugged it from the wall socket and plugged it back in, and it began glowing blue again. However, when I plugged it into the computer and tried to turn it on, the computer would not power on and the cable turned the light off again. Nothing I have tried to do has solved this and I am getting no beep codes. Any help would be appreciated. Thank you.
