So the problem is that I can turn the computer on (in the sense that I hear the startup sound, and the little light on the cover release button lights up) but that's all that I get. I looked on the mac website and they told me how to reset my parameter RAM, which I tried....but there is still no effect. I had the same problem with my macbook pro around the same time one year ago. The last time this happened I finally just kept frantically pressing the power button and magically the monitor showed up. Anyone else experience this?
