Hey guys sorry if I break any forum etiquette as this is my first post, but I have a question regarding my old outdated laptop. When I originally purchased my Dell Inspiron n5010, it came with an ATI Mobility radeon chip and an i3 without intigrated graphics capability, however about a year ago I replaced the i3 with an i5-460M which does have HD graphics. My question is that since I no longer use this as my main computer, is there a way to enable the HD graphics and completely disable the power sucking discrete card? Ideally I would want to underclock the processor and have it as a low power note taking laptop running mint or something, but from what I understand that isn't a possibility.
