Yes, that's the problem I'm having. I have an older MBP (1.83 Intel Core Duo) When I push the power button, I hear a little electric noise, then a fizzle noise. It won't turn on. However, if I close it almost all the way and turn it upside down, it powers up fine. Once it's running, no issues. Any idea where to start with trying to correct this problem? I don't know what part could be making this happen. And yes, it has to be both upside down and almost totally closed.
