I have an early 2011 15" MacBook Pro (specs in signature) and it seems like it always uses the AMD graphics. I have it checked in System Preferences to automatically switch, and I also reset my PRAM earlier today to see if it would make a difference, and it did for a little while but now it went back to how it was. As I'm typing this, I'm on battery with iTunes, Safari, and Software Update running and it is still using the dedicated card. Is there anything else I should do to try to get it to be able to use the integrated graphics. I'm going on a 6 hour flight this month so I kinda need to stretch my battery life as far as it can go. Thanks for any help!
