I don't quite understand what you're saying. Are you asserting that modern Mac computers will not turn on without a battery installed (which is not true in my experience), or are you asserting that trickle power is a bad thing (also not true in my experience)? Maybe I'm missing your point altogether. Edit: did some research, I will admit it is possible that newer MacBook pros with an embedded battery may not power on if it is not connected (not sure about this). But I know my 2010 15-inch MacBook Pro does power on and run without a battery connceted (I use it as a media server), and I'm pretty sure most MacBook airs would run without a battery connected as well.
