So as described in other threads when running bootcamp you are forced to use the discrete GPU, that's a bit of a down side on battery life I want to try and minimize. I need some gaming but I am trying to figure out if there is a way to better battery life for work related activities in windows. Three questions: 1. Work activities would be some light/moderate SQL usage with a proprietary tomcat based application and IE work. Do you think this type of thing virtualized just wipes out any savings I would get by turning off the discrete GPU? 2. When using vmware or parallels can I point it to the bootcamp partition and force it to use the intel integrated graphics in an attempt to save power? (I'm thinking this is a NO) 3. Or does it make a difference if the whole windows os is installed in vmware or parallels? I wouldn't be completely opposed to have one for gaming and one for work power saving but only if it makes a real difference. The machine in question would be a late low end 2011 15" with the quad i7 and 6750M.
