Macbook pro intel core duo; My macbook is turned off, when I press the power button the light goes on and the computer starts making sounds of turning on for about half a second and than shuts off... I tried removing the battery and putting it again, I tried to hold the power button (the light flickers at one point and eventually shuts off as well after 2 seconds), and tried turning it on with the adapter plugged in and unplugged. Can anyone help me with this?? I'm desperate and no more warranty for me... )): Thanks!!!
