I got this laptop about a week ago. I haven't done anything that might explain what's going on. I closed my computer for the night and left it to charge on my desk. The battery says it's fully charge and the power light is on, but the screen is completely black and the computer is totally unresponsive. The lights stay on even if I try to turn it off by pressing the power button or even if I removed the battery. I can't get it to do anything, and I'm really freaked out because like I said I only got it a week ago and I have no idea what caused this. Please help!
