Hi. I have an HP Pavillion laptop (can get the number for you when I get home). I was on the internet one day and my computer froze up, so I turned it off. When I tried to turn it back on, the screen was plain black. It's been doing this for the past few weeks. The power light stays on. But the disk drive light lights up for about 2 seconds when I turn the laptop on, and then it blinks off. You can also hear the noise the disk drive makes for a few seconds, and then that turns off as well. There are no fans running or anything, my screen is just black, and the computer is silent. Any idea what's going on? Is my laptop dead?
