Weird. I just returned from a friend, wanted to wake my MacBook up and noticed it was shut off. Well, i thought i might have gone too far into Zero-Battery so i just booted it up again. But heck no. It doesnt boot, it just turns the "Sleepy LED" back on a bit and starts a cooler Fan at extremely high speed (as if it would be cooking hot, but it is not) I can push the Powerbutton again for some secs and it shuts off again, but it always comes up with the Fan and only the Sleep-Led. Nothing more. The screen does not even Flash or get light, no sound. I tried resetting PRAM and SMC. no success. and now .. i'm done with ideas I hope you got any. 2 Month "old" baby.
