I'ts happened before, but I don't remember it taking this long. I shut the computer off hours ago, and when my mom went to turn it on it does nothing. Pushing the power button does nothing. Afew months ago I went into the case, and accidently forgot the power cord was still attached and ripped it open. I noticed it was missing a prong on the power button but later found out it's supposed to be like that. I have been able to use the power button but sometimes it won't turn on. Could it be the cable? I also thought maybe the PRAM battery? I hit the reset switch on the motherboard and still no response when i tried pushing the power button. Please help
