Screen went black (by 5 users)

Hello.
I recently bought a acer aspire 3680 laptop. Everything was working fine until today. I was just browsing around on my computer when the screen went black. The computer STILL SEEMED TO BE ON. All of the lights were lit up and the laptop was "humming" like normal.

On my home computer I went to acer support, they told me it was a ac adapter problem so I took the following steps:

*complete a 'power reset' of the notebook.*

1. Unplug the ac adapter. Keep ac adapter unplugged.
2. Remove the battery and keep the battery unplugged.
3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
5. Normally power on the notebook.
6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

After doing all of that, the battery indicator lit up so it wasn't a problem with the ac adapter. I started up my computer, the screen was still black.

If you need more information tell me...
