I have the above laptop and recently I had problem with it being the fact that it will not boot properly. Each time the power button is pressed, it will only try to boot for less than a second and it will shut off again. I have tested the ac adapter and it appears fine. A few of my friends said it could be a motherboard problem. Has anyone had this issue before? I was wondering if anyone knows exactly which part of the motherboard that is faulty so that I do not have to replace the whole motherboard. Any suggestion or inputs in resolving this will be greatly appreciated. By the way, everything is standard, has not been modified or changed. Thanks!!
