Hey there arpadm,


It sounds like your screen is black, but you can otherwise tell the computer is on. I recommend these steps from the following article named:


Apple computers: Troubleshooting issues with video on internal or external displays

http://support.apple.com/kb/ht1573

Reset the system

You can reset the Mac's parameter RAM and SMC.

Reset the resolution

Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:

  1. Start up in Safe Mode.
  2. From the Apple () menu, choose System Preferences.
  3. Choose Displaysfrom the View menu to open the preferences pane.
  4. Select any resolution and refresh rate that your display supports.
  5. Restart your computer.


Thank you for using Apple Support Communities.

Cheers,

Sterling
