Question about Dell Latitude D400 Notebook
The screen is black after the startup dell ad is flashed. The light up key with a closed padlock with the number 9 in it is illuminated. I don't know what that means. If you hold down the number 9 key for about 3 secs. it will start beeping with each keystroke. Same exact problem on my Latitude D400. I ran the diagnostics with F12. All systems pass OK. I do not have the utilities disk and no diagnostic partition. I plugged a regular CRT to the laptop and that does work. If I switch back to the LCD, it will work for a few seconds and then flicker out or turn a dark reddish hue and then flicker out. Could this just be a problem with the LCD itself or maybe the ribbon connector problem?
The lock key with the number 9 just means that the system has not completed booting.

I had that happen to me with my Dell as well... If you're comfortable with taking a laptop apart.. you'll need to detach the screen ribbon, clean it with rubbing alcohol, and then reattach it. This should do the trick..
