First of all, reading through the threads and posts has been most illuminating and helpful. Thank you all. However, I did not recognize anything that would help me with my current problem. For whatever reason, my Energy Saving Preferences has disappeared completely from my MBP. I wondered if it had anything to do with installing SMCfancontrol so I removed that, verified repaired all permissions, reset PRAM...all of the "normal" suggestions have been tried. There is no sign ever that I had Energy Saving anything. Even if I click on the battery icon and click Energy Saver Pref....nothing happens. Keep in mind I am not a computer guru, but I can follow directions. Thank you in advance for any suggestions.
