Does anyone know how I can keep my 2011 MBP from switching graphics during battery use. I want to keep it on Integrated Graphics while I am using the battery. I am monitoring the graphics through the gfxCardStatus app. The app has settings for Integrated Graphics only but when I launch some apps (i.e. Twitter), my MBP switches to Discrete Graphics, which drains my battery. It seems gfxCardStatus does not keep it from switching to Discrete. I am running Lion 10.7.1. Thanks
