Hi. I have a Dell Inspiron 6000 that's about three years old. Starting a few days ago, the monitor pretty much refuses to light up if I have it plugged in. If I start it up with it plugged in, the screen lights up intermittently during the startup, then quits once my desktop appears. If I want it to light up again, I have to shut it so it goes into sleep mode. When I open it again, if I have unplugged it, it will light up in power-save mode just fine. Any idea what is going on here? I've tried a friend's power cord, and that does not appear to change things. I'm running Windows XP. I'm not sure how that would affect anything, but I really have no idea why this would be occurring. Any help would be greatly appreciated.
