I'm hoping someone can help me here.
I have a Gateway Laptop Model NV73A. All of a sudden it will not post. It will power on but that's all. Specifically, when I press the power button the power light illuminates, the DVD drive clicks a few times, the fan turns on and then nothing. I *THINK* the problem is the cable running from the motherboard to the screen hinge has come loose. Therefore, it doesn't think the screen has been opened when in reality it has. However, I have NO idea how to get to it. 
Has anyone experienced this problem that can help me out here?
BTW, I've tried the power reset several times.
Thank you.
Sincerely,
