Resolved Question:

I accidentally closed my 2009 Macbook in the middle of startup, and now the screen flashes wildly and shows the desktop and then immediately goes black. I am now connected to a monitor and it works on here, but will not on its original screen. What should I do?

I have now tried that as well, and no luck...sometimes it will come on for a second when I disconnect it from the monitor or re-connect it to the monitor...I don't know if this helps you...
Thanks,

Does it do it when the power has plugged in. I assume it does, I believe that you need to change the PRAM battery. That is why reseting it did not do the trick.

Here is what a PRAM battery looks like.

I would look into replacing the PRAM battery. Let me know if you have any other questions. If this answer was helpful please take a moment to rate the answer with a rating of three top ratings.
