Question about Dell Inspiron 6400 Notebook

Screen still goes black and gets worse when adaptor is plugged in

I somehow managed to get my screen to work enough to download the new display driver and BIOS updates and install them, but my screen continues to flicker and go black like before, and now I have noticed that when i plug in my ac adaptor power source the screen immediately goes black and cannot be reversed. What is the problem here? why is this continuing to be a problem?

That sounds like a hardware issue, not driver related at all. You could try doing a system restore to when it did work, but that probably won't help.
I'd suggest opening it up and reseating the plugs to the lcd panel, but anything more than that gets complex very quickly. It could also quite possibly be an LCD inverter problem, in which case your laptop needs to go back to the manufactuer to get fixed. (You "could" look for a new one on ebay and install it yourself, but that's very tedious, and kinda risky if you haven't done it yourself before, and I'm not about to help a rookie break a laptop that's already in rough shape.)

When i plugged in my laptop screen goes black but charging..i want it back from normal..


you somehow disabled the screen by setting it to display only on the connected TV. while connected to the TV, open control panel, click on display, click on screen resolution then you can select detect and identify and you should see your laptop screen identified as 1 or 2, also the drop down should identify both screens so you should be able reselect the laptop screen, set the resolution, etc. If not, click on advanced settings and depending on your video driver, you should see options for video properties or graphics control panel or something similar where you can select one screen or the other, both to be the same or extended where you can use both simultaneously where you can have different apps on each screen and you can move your mouse between them. Usually there is some option to revert to default to get back to basics.
