So I want to get everyones opinion. I am not as tech savvy as I would like to be and the MBA HD is my first Mac purchase computer-wise (proud owner of first gen Iphone and iPod nano). I was curious if any of you think that core shutdowns can be resolved via software update. Updates in the past seemed to fix some problems. Like myself, many of you resorted to coolbook which is great but sometimes I ponder why my hard drive is at 6200rpms meanwhile the only thing that is running is Safari. Please chime in with your opinions and perhaps some better coolbook settings (lol). PS I am using the settings from the "huge success undervolting thread"
