My backlight on my Dell Inspiron 1150 does not seem to be working, my screen is dim and I can barely see a thing. I contacted Dell and they are sending someone out to come and fix it. The thing is, When I first turn my computer on, I can see the Dell logo fine, the light works, but after like half a second, it goes out. I also noticed it turn on for a half a second when I pressed Fn-F8 to turn on the external monitor. Does this mean that the light is working and that it could just be a software or driver issue and not a problem with the backlight?
