SOURCE: no signal
The output video needs to be enabled on the laptop. Normally this connector is not active. There should be a function key that has the outline of a CRT screen on it. Using the ctrl key and that key at the same time will toggel the output video connector on/off. If that does not resolve the problem, please update this with your exact setup including cables.

The lamp cover has a disconnect feature such that the power wont be activated that it won't allow power while the cover
is off. Sometimes the piece of metal gets bent out of place.Try removing the cover for the lamp, and bending the little piece of metal forward.
It worked (in my case) when fiddling with one such piece, dumped in the store, when I was the Hardware *** Network administrator of a govt. sponsored university. I just opened it & then when I could'nt find out Why ??, so just cleaned it and observed this small metallic tag which simply looked like a clip, so I assumed it's a clamp to hold the lamp cover in place when in use.Tried rubbing it to clean it in case its still has enough pliability, by fiddling with with my insulated tester *** screwdriver, without unplugging the power chord !!!!! It zapped my eyes as the lamp got activated wile looking closely at it(a bad habit of mine, just a bit more curious than any cat)....sodeep
