Macbook not responding blackscreen power on

#Macbook not responding blackscreen power on pro

It's always been a bit slow, but I figured that was normal for a used computer. My friend did drop the computer at one point, but that did not appear to cause any problems (other than some external, cosmetic damage). It belonged previously to a friend, and I received the computer in good condition. My computer has had no serious problems in the past.

When I hold the power button down to its eight second limit, the sleeplight will initially be bright, fade, flicker, die out, come back for a second, and then the computer shuts down.

The screen is always black, and there is never a chime. I can hold the power button down for eight seconds and hear it starting up before it forces itself to shut down. Essentially, it turns on for a second, but powers down immediately. This is what's happening: I'll press the power button, and if I release immediately, it makes the same noise it does when you force shut down. I then held the power button down for a few seconds, and I heard the computer shut down, indicating that the computer had been on the whole time, just not responsive. I hit the power button, and nothing happened. I clicked, pressed the space bar, hit random keys on the keyboard - nothing. When I opened it this morning, I expected the computer to boot up as usual, but I was greeted only by a black screen. I didn't shut the computer down, I simply closed it and let it sit for the night.

It was working perfectly fine last night.

I have a 2009 MacBook Pro that won't turn on.
