Disable "Your computer may use more energy with these settings"

Question

I frequently use my laptop for presentations or video chats, and I frequently have to turn off my screen saver and disable all my Energy management settings to prevent that stuff from showing up during a presentation.
However, every time I drag the Energy Saver timers around, I get the annoying message:
"Your computer may use more energy with these settings"
The box forces me to hit Okay to acknowledge this painfully obvious message. How do I disable this prompt from popping up every single time I adjust my Energy settings? Plist setting somewhere perhaps?

Thanks Livia and Huevoos (eggs??) for your interest in this post.
In a nutshell, I haven't been able to solve this. I gave up on Apple support after they proved useless.
As Huevoos suggested, and I confirmed it time and again after browsing thru endless forums, it seems that the user validation routine for the Mac App Store is done by looking into your network settings, which in my case are either incomplete or erroneous due to the broken-down ethernet. (I am still waiting for somebody more experienced in this forum to contradict or explain this).
So, because I still have wireless connection, I can use my machine for day-to-day chores, have not been able to purchase anything up to this date in the Mac App Store though. I'm waiting for either a software update that could correct this (Mountain Lion??? there's no guarantee only hope) or the moment when my machine will need to be replaced by a new one with a functional ethernet.
I'm sorry I can't be of more help. But I'm pretty much in the same situation as you guys.
Live long and prosper.
