Magic Mouse/Bluetooth Gone?

[zotter87]

I have the magic mouse and have been using it without incident for the past few months. Yesterday I turned my MacBook on and the mouse no longer worked. The bluetooth icon on the top right of the screen is gone, and when I got into system preferences and mouse, it says it cannot find a mouse. The mouse itself is still in perfect working order (green light etc.). I also just performed all updates. Hopefully someone knows what going on with this.
Thanks.

go to system preferences and make sure bluetooth is on, there is also a checkbox there for "show bluetooth status in the menu bar"

I know there had been a bluetooth icon in the system preferences before, but there isn't one there now.

Have you tried resetting PRAM/SMC? Repairing disk permissions? If those still don't work, it may be a faulty Bluetooth card.
