I hope someone can help me! I have an HP Pavilion ze4300 laptop. A week ago I turned it off one night, and when I turned it on the next day, nothing on the screen. The lights come on, the fan works, battery is ok, everything, but the blue hard-drive light in front does not flash. I've had an IT guy at work look at it with no help. It has comeon a few times, but as soon as it's turned off, black screen again most of the time when I try to turn it on. Any ideas or advice or suggestions?!!!!
