bluetooth

So, today, I decided to turn off bluetooth to save battery power. When I did so, it did everything like normal. Whatever. But whenever I want to re-enable Wifi and Bluetooth, it just has "Enable Wireless" and "Enable bluetooth" grayed out in the respective things on the top-right of the desktop. I am using 12.04 Precise Pangolin on a Dell laptop that has never had wireless problems before. Clicking the grayed-out part does nothing. Re-logging and restarting has no effect, and I'm on an account that has full administrative permission.

My attempts:

~$ sudo dmesg | grep wlan0
[19.960211] ADDRCONF(NETDEV_UP): wlan0: link is not ready

.

~$ sudo dmesg | grep blue

[[nothing]]

What do I do to manually re-enable wireless and bluetooth?
