"While I was benchmarking third-party RAM with a MacBook Pro this week, I noticed that the computer was taking a huge hit in performance when it wasn't running on Apple-supplied memory. A minor decrease in performance might be unlikely, but a 37 percent plunge in processing power seemed impossible. After some backtracking, I realized that I had been running the benchmarks without the battery installed after I'd swapped out the stock RAM for third-party memory."

Seeing as Apple has documented this issue, it is apparently known and designed.  That being said, it just seems odd and everyone discussing it right now seems almost completely baffled by it.  The explanation, in theory, makes sense.  They don't want to overdraw power that the power supply can't handle by itself, but if that's the case how come we haven't heard of this same issue with other manufacturers?  I personally think the MacBook is an alien device that we've yet to fully grasp the function of and at some point we'll all be sequestered in a room and debriefed as we're handed new notebooks, but that's me.  What's your theory?

I'm pretty sure every notebook does this. My Thinkpad cuts the CPU from 2.2ghz to 1.2ghz when I take the battery out. The linked article has some good comments explaining this, and mentioning this is not new. Storm in a teacup, methinks.

I think so. I mean how many people ever even do this to begin with?

I think it just caught people's attention because it's kind of weird.

Maybe because it's just Apple. There are many things to dislike and critique Apple over, but this isn't one of them.
