I cannot turn Bluetooth off on my MacBook Pro. I am running 10.7.4 and the option to turn it off is grayed out, both in the toolbar and in System Preferences. I used Onyx to reset permissions but to no avail. Help, please! I am not using any Bluetooth devices and I'm not sure when or how it got turned back on, but I've always made sure it was turned off. My battery is paying the price!

I would install a clean copy of OS X on to an external drive and test to see if your current OS is corrupt. If the hardware doesn't let you turn it on or off with a clean install, you have saved yourself having to back up and erase the internal drive and know to take it in for repair.
If you find it's corruption, you could then run Migration Assistant to take the data from the internal drive to the new clean OS and re-test before doing the erase and copy of a working OS with your personal data and settings.
