Here are my SetCPU profiles to get your NC to get 12 hrs+ of moderate use per charge and make your NC a little more responsive. Main Tab: -Set Scaling to "ondemand" -Check Set on Boot Profiles Tab: -Check Enable -Check Notifications (optional) -Create these four profiles and check them Advanced Tab: -Change Up Threshold to 35% (optional for speed and snappier responding NC) Definition: Up Threshold tells the cpu when or at what load to scale up. The lower the %, the less load it will take and the faster the cpu to scale up, the higher the %, the slower the cpu will scale up, therefore conserving even more power. -Check Set on Boot Edit: Tip below is best for devices with 3G not the NOOKcolor Additional power saving tip: Leave your NC connected to any wifi network as much as possible throughout the day. Know other settings or profiles, post um if you got um.
