Hey so I was on my laptop at school, closed it and headed to a lab meeting I had. Once getting to my meeting I opened the laptop and expected it to start back up but it just sat there. I hit the power button to see if it would start back on and it wouldn't. So I held the power button down and heard it click off. Then I hit the power button to turn it back on and the cd drive will go on and then the sleep light comes on then it goes off. Holding the power button lets it go for a little longer then the sleep light blinks a couple of times and then computers off again. Im not sure whats happening. I have tried all of the suggested ways to fix it but it will not turn on. Is it the logic board(after reading a couple this is what I'm assuming it might be but hoping its not) or could it be the video card?
