blue tooth mouse light flashing

I'm having the same issue. I have a mac mini with wireless keyboard and wireless mighty mouse.
now all the mouse will do is blink the green light, I can't detect it in bluetooth or anything.

Please Help !!

I had similar problem.
I replaced the batteries just as a precaution.
Then the only way to get it to work was to slide the switch underneath HALFWAY only.
After a few seconds I then slid the switch open another click and it connected.

Hope you have some luck.

Got mine to work:
here's what I did, I'm not sure all of these steps are needed, but I'll throw them out there just in case they can help.


1) turn off Mighty Mouse
2) Remove Batteries (replaced with new ones because I couldn't remember how old the batteries were)
3) turn mighty mouse back on
** at this point mine was still blinking as before

4) Open System Preferences
5) Open Bluetooth Preferences
6) Click the "+" sign to add a new device
7) Click Continue
8) Click the radio button for "Any Device" NOT "mouse"
9) Click Continue
* My mouse actually showed up as an available device at this point.
10) proceed to finish the setup process
* Mouse started working


Hope that helps !
