Is my Magic Mouse Dead?

Seems like no one has an answer to the failed hardware. I guess I'll drop by after work to see if Apple can do something for me.

Last night the mouse was working fine, this morning it won't turn on. no green light, nothing. I tried 2 sets of new batteries.

Im already hating using a cord mouse.. i can't scroll horizantally. it's ********. i want my magic mouse 😟

I keep insisting that this should be a problem of Mountain Lion or Mac Mini, because my mouse was working perfectly with my iMac with OS X Lion installed, but now isn't working properly with my new Mac Mini with Mountain Lion installed. Sometimes it becomes erratic, it's difficult to control the pointer, and then I have to turn it off and on to correct the problem.

Wow everyone. I am just a standard older person using a bluetooth mouse. completely baffled as to why my mouse stopped working. No Green light. Well...... just put decent batteries, not Duracell, with longer bits on the end. Incredible. Nearly bought a new mouse...... Thanks to these discussion pages......... and you clever lot out there....

Magic mouse no green light problem. Similar fix as pamelafromyateley. It's the batteries.

Yes, thought my magic mouse was dead too. Working perfectly fine one minute, absolutely dead the next, simply would not turn back on. First tried new batteries of course. Nope. Still no green power indicator on mouse.

Tried 2 brand new sets of rechargeable alkaline batteries still with no luck (same brand as ones that were already working in it when it finally died). Batteries all tested showing full power.

Put in third set of regular alkalines, used ones in fact (Duracell actually), green light instantly came on and the mouse was up and running again. Go figure!

So, try couple or three different sets, types, and brands of batteries folks, may well be all you need to get it going again.

(And here's another "go figure" for you: just for fun just now put the rechargeables back in that the mouse first stopped working with and continued to refuse to work with, and now its powering up fine with them again.... ghost in the machine! :-))

Sergio:

Yes, Nicad rechargeables are usually 1.25 volts ea, but rechargeable alkalines are 1.5 volts ea (or mine all are at least, and all were tested with a meter just to be certain).

And as mentioned, the magic mouse was working perfectly fine with those same rechargeables (which still registered a full 1.5 volts ea), both when it died, and again after I'd tried other brand new alkaline batteries, swapped the batteries back and forth and then reinstalled the exact same rechargeables after all was said and done.

I'm suspecting after the mouse inexplicably dies, the mouse internals for some reason are needing a little "electrical tweak" of some sort which somehow occurs from swapping the different batteries around a few times, and as a result then the mouse is somehow "retriggered" to power on again. Certainly worked that way in my case anyway.

The used Duracells that I put in that finally got the mouse to repower on only had 1.3 volts ea... you would think the nummerous higher power brand new batteries at 1.5 volts ea I tried would give better results, but not so in this case.

And even though the mouse wouldn't come back to life with new 1.5volt batteries, after "reawakening" with the old 1.3volt duracells, now the mouse continues to work perfectly fine with the original 1.5 volt rechargeables that it originally died with.

For some inexplicable reason the mouse suddenly powered itself off and would no longer power on again no matter what (brand new alkaline batteries or otherwise) UNTIL swapping in the lower voltage 1.3v duracells... perhaps the fact the used duracells had less voltage than the new alkaline 1.5v batteries, the duracells voltage drop somehow managed to "tweak" the mouse out of whatever glitch it was in.

The main point here is, if your perfectly working Magic Mouse suddenly will no longer turn on (as in, no green power light indicator even with brand new batteries), don't assume your mouse is permanently toast as I first feared and others here have thought.

Try several different set of batteries, even old lower power ones. It might just tweak your Magic Mouse back to life as happened with mine.

But as I said earlier, I think this problem probably can be related to Mountain Lion, because I was using the same mouse for a long time with an iMac running Lion, and this problem began when I connected it to a Mini Mac with Mountain Lion.

Yes Sergio, as you say, YOUR issue may well indeed be entirely related to Mountain Lion and nothing else.

I don't have Mountain Lion. I have Snow Leopard. And fortunately I have never had any connection issues with the mouse which you are suffering from.

I attempted to be clear that my posts were ONLY addressing the issue that started this entire thread, the fact that the Magic Mouse would suddenly no longer power on. NO GREEN LIGHT on the bottom of the mouse. The original poster was having this exact problem, as did I, which was why I posted my "fix" in the event someone else might be suffering similarly and if lucky this same "fix" would work for them likewise.

If the mouse won't turn on in the first place, then Mountain Lion or any other operating system will not be able to communicate with it no matter what, poorly or otherwise. I'm sorry to hear Mountain Lion is causing issues with yours and hope you soon find out what is causing those problems. I can certainly appreciate your resulting frustrtations. Thankfully for me, my battery swapping experiments with new and used batteries back and forth in the mouse totally fixed MY problem and I'm once again a happy Magic Mouser. I hope you shall soon discover your own fix likewise to end your frustrating Mountain Lion connection woes.

So, my posts refer ONLY to folks whose Magic Mouse simply will NOT turn on, even with brand new batteries installed. No Green Light on bottom of mouse.

Anyone having actual mouse connection issues using Mountain Lion or a Mac Mini should follow Sergio's posts for I'm sure a fix will pop up for him to post soon. Good luck Sergio!

(BTW: perhaps these mice are somehow getting into a "bluetooth lock" of some sort, which may be part of all of our issues here, which might explain why for some folks resetting the computer pram "clears" or resets the mouse bluetooth to work again, and may also be why the mouse locks itself off in the first place and then refuses to power on again until its own bluetooth is tweaked somehow, either from computer pram reset, or voltage fluctuations from numerous battery swaps, or battery terminal cleanings etc.

I previously experienced bluetooth stereo headphone connection issues while trying to stream video to an ipad which were only fixed by changing some settings in the wifi router (- really!) to keep from dropping the bluetooth headphone audio connection between the imac and the ipad. Go figure, change the wifi router to fix the bluetooth headphones. But it worked!

And on that note Sergio, maybe even try moving some of your equipment around a bit. Perhaps its and/or the mouse are somehow picking up interference of some sort and causing your glitches. The above mentioned bluetooth headphone issue was also agravated by where they might be and what might be in between them and the signal source (other electronics, walls, chimneys, whatever...). The Mini is certainly easy enough to try in a diff't spot for a bit and see if you notice any change. Could be interference from something as simple as magnetic field from poorly shielded speakers nearby, or even a nearby television or telephone, etc. Hey, you never know!... worth a shot if it works! Again, good luck!)

I had same problem as many other people above. My Magic Mouse is two years old and for the first time since I've had it the low battery warning came on last week. Yesterday the batteries finally died, so I bought some more this morning and the mouse still wouldn't work (no green light). Having read above posts I tried the SHIFT+CTRL+OPTION button trick and that didn't work, nor did cleaning the sensors. Finally, I tried both pairs of batteries from my TV and Sky remote and they both worked fine. The original batteries were Energiser, the new ones I bought today were Duracell and, weirdly, the ones from my remote controls were one pair of Duracell and one pair of Energiser!?

So just as someone above suggested it seems to be a lottery when it comes to the brand (or even specific pair) of batteries which will work...

Besides all the problems with the Magic Mouse, I have noticed now that with the Mountain Lion the battery lasts less than half the time it lasted when I used it with Lion. I wonder what is going on with this new OS?

I think I'm going to use back my old wired Apple mouse.

It's a pity that I will lose all finger commands that are embedded in Mountain Lion.

Hi,

I had the same problem. My Magic mouse inexplicably just stopped working one day- no green light, no anything even with new batteries. I thought it was gone for good- but weird because it's never been mistreated, dropped, or anything and always used in a clean environmnet. It looks brand new apart from the fact its about 2 years old.

After reading this thread, I cleaned the battery connectors, even though it looked like there was nothing on them, I just rubbed them with a clean dry cloth. I put in another set of batteries, and it just started working again.

I've got absolutely no proof to back this up, but I suspect it might be some kind of build up from using alkaline batteries. But I could be totally off the mark.

Coincidentaly, both magic mice on our home desktop imacs stopped responding within a day.

I changed batteries several times without success until reading your post. After scraping the terminals, we are

up and running on both computers. Thank you DaveLord.

I started having the same problems, especially after changing batteries. After trying some of the posted remedies I noticed the small access holes for the + end of the batteries. I put a small piece of foil into each hole to allow for better contact. So far so good. I will update if this turns into a long term cure.

Update: the foil I placed in the battery + holes did not work long term. I have found that when left Idle my mouse will link to my wife's Imac in the next room, therefore it stops looking for my mac mini. This, along with unwanted zooms, is a new feature that came with Mountain Lion. I will keep searching. Maybe a new address, though I'm not sure how.

My Magic Mouse died this morning. I was using Duracell Plus Power batteries which my computer had already told me were running low on power.

So when it died this morning I put new batteries in which happened to be Duracell Ultra - No green light, tried 2 sets of batteries (both of which worked fine in a torch) and still no light.

Dug around the kitchen drawer and found a couple of Duracell Power plus in the back corner - Put them in and hey presto! Mouse working again!!!

Weird!

SO i left the dead mouse on my desk and forgot about it since I got a new one..

4 months later, I switched it on and the magical green light went on! So happy! Now i have 2 magic mouse, one for home, one for office.

I think it had to do with the Aluminum housing that makes it much easier for condensation or corrosion to build. leave it indoors for a while to dry out and it should work again.

cheers
