When unpluged, my 15' pro always use AMD praphic makes my battery only work for 2-3 hours. Is there a way to stop computer using AMD graphic card when i'm not playing game???
MacBook Pro (15-inch Late 2011), Mac OS X (10.7.3)
Configure using Energy Saver preferences, although I think it's supposed to change automatically on battery power.
Check under your "Energy Saver" and turn on graphic switching, this way it will use the Intel HD 3000 graphics as much as possible before having to use the AMD video card.
i'm using energy saver prederence, but it still stay on AMD all the time.
I'm sure the Graphic Switching has been turned on already. But...
Run through this list of fixes, if you do #16, give it some time to make sure and come back to report.
Try using this software (It is 3rd party but it is safe) called gfxCardStatus. It just places itself on the top bar or side bar (not the dock) it will probably be a d in italics (this is italics for those who don't know) or an i. Just click on it and click on the Integrated Only option in the bar which will switch the card to the original integrated graphics card. Also, check for dependencies bellow the "Dynamic Switching" option (if there isn't just skip this) dependencies can cause changes to your graphics card usage and may be the problem; for me it was but who knows it might be some internal error. If you don't trust me I totally understand just putting it up there for those who want it. You can follow the above option by "ds store" which might also work.
