|If you never see anything at all on the screen then it is most likely a hardware fault and nothing to do with msconfig. What were you trying to fix (wondered if the symptoms were that of an impending hardware fault)?|
I know it's a difficult question but does the notebook "sound" as if it is starting and do the usual lights flash?
It could be worth hanging on an external monitor just to make sure it's not a screen fault. Also with the computer on try closing the lid slowly (not fully) while watching the screen. If you see something flash up on it, it can point to a problem with the cable where it hinges or with a connector at either end.
Always pop back and let us know the outcome - thanks
