My malfunctioning Magic Mouse: Why would replacing previously-reliable rechargables with regular AAs revive it?
When I woke up my iMac this morning, its Bluetooth-linked Magic Mouse wouldn't follow its example. And replacing the rechargeable AA batteries with a fresh set didn't do anything.
Following tips shared on Apple's tech-support site (https://discussions.apple.com/thread/2742686?start=0&tstart=0), I cleaned the contacts inside the mouse with rubbing alcohol, even though they already appeared clean, then did the same with the terminals on those AAs, where the negative terminals looked slightly oxidized; neither helped. But then I popped in a fresh set of disposable AAs, and the mouse woke right up. A newer set of rechargables also worked.
Now I'm relieved and puzzled. Are the contacts inside the Magic Mouse that picky? What else might explain this?
