Is my Magic Mouse Dead?

For me, it was a battery contact problem. I swiped the contacts with a Q-tip dipped in isopropyl alcohol, put in new batteries, tried IB Retired's reset, but nothing worked until I pressed both batteries hard into the recessed contacts. That finally worked. I hadn't seen the pushing trick mentioned, so I thought I'd post.

I tried what Davelord has posted. Thanks.

Opened the mighty mouse battery compartment and with a small flat screwdriver, carefully scraped off some form of white film build up on both positive and negative contacts and replaced the batteries and instantly.....mighty mouse is back to life. Try it.....really worked.

I had the same issue but fortunately could figure it myself. There are different manufacturers of AA batteries. Some have a small dot which is somewhat protruding upwards at the positive side and some batteries have a flat plate at the positive side.

In Mighty Mouse only the AA batteries having a flat plate at the positive side will work. The dot somehow will not work though the batteries are of the same power and specifications.

Though strange this is the problem definitely.

I tried with so many batteries, only the one specified above worked. For an example, Energizer works fine, but not Duracell..................

This happened to me today. Changed the batteries, no light.

After reading this thread I gave the inside of the mouse a little dust and it works again.

But it shouldn't have happend.

I'm assuming there's USB mice which will let you side scroll and flip between pages?

Yesterday while powering down my MAChine, my Magic Mouse opted to not be a participant in the daily festivities. I changed the batteries "right-side up" and even had a stare-fest of sorts with this now non-working gizmo. So, thinking it may be due to dated batteries which had been given to me by a CubeMate that were the last two in a box of a gazillion, I changed to yet and still another pair of batteries. Still no power. I swiped a usb mini-mouse from another computer long enough to see if I'm the only one who had to engage in a magically stare-fest and search for possible solution(s). Since my Magic Mouse is tethered via Bluetooth I looked to see if there would be a dialogue such as "hold hands" or "reignite the love" or "communicate from the big guy to the little guy"...or simply "Connect." And sure enough, after following the Blue Tooth icon --> Devices --> Apple Magic Mouse --> "Connect" path, we are as one again. (Remind me to go retrieve the other batteries from the "trash".)

Hope this helps!

Ok, forget it.

I conected the magic mouse to other iMac (and to Windows 7 in Bootcamp) and the problem continues.

So it's an hardware problem. the lens are dead probably. I'm a little ****** off rigth now. My mouse has 1 year and 2 months, this is no time span for a mouse do die. Bad luck or bad design? You decide... Apple.

- Hello Mighty Mouse, can I join you in this box of retired and hopeless Apple artificial rodents, please? -.-

I had the same problem, tried all the suggestions, nothing worked. So just as I was going to bed, defeated I thought I would try the batteries out of the TV remote and guess what, it worked. I don't pretend to understand it, maybe Apple has had a falling out with Duracell, who knows....

IB Retired's solution also worked for me. There seems to be two main issues people posting in this thread are having. One is the PMU that needs resetting (IB Retired's fix), the other is that there is an issue with the batteries (wrong type/thin layer of film on connectors etc). You can tell which of the solutions to choose based on the green light on the mouse.

If the green light is showing, but no connection, try resetting the PMU using IB Retired's Ctrl+Shift+Option fix.

If the green light is not showing, this is a battery issue (kind of obvious 🙂).

I was using my mouse with an iMac. But now I bought a new Mini Mac and an strange thing happens:

When my mini sleeps for a long time (overnight, for example), after it wakes up the mouse doesn't move anyway. I then shut it down and up several times but the greens light doesn't light, it appears to be completely dead, even with new fresh batteries. If I wait for some minutes and then try again, then it begins to function normally.

I cannot figure out what's happening.

No, Bluetooth is ON. If bluetooth was OFF the mouse couldn't work anyway.

The only thing that makes my mouse wake up (I remembered that I did this when I had Windows installed in my iMac and the same thing happenend at Windows startup) is to hold down the mouse button until it moves the pointer. I think that something is turning my bluetooth 'lazy' and this is probably the reason for the long delay in waking up.

just happened to me today. The little green light does not light up. (It has been acting funny the past month). Put in several sets of brand new batteries. No green light. But then I followed someone's advice, used a qtip with rubbing alcohol, and scraped the leads. Seemed to work. yay!

I didn't wanted to open a new discussion, so I just ask here. What can I do if the positive round thing in the magic mouse is slightly pushed in and the battery can't connect properly? I tried a tinfoil, but it worked only for a while :/ ...

Sometimes my mouse suddenly becomes erratic, and it's difficult to control the pointer. Then I have to turn it off and on again, until it's paired with the computer.

I never had any problems with this mouse until I became to use Mountain Lion.

Hi

I have had my Magic Mouse for roughly 2 years and the light has stopped coming on. Went to the Apple Store in Milton Keynes where I was asked if I had Apple Care - I said no.

At this point the fairly useless chap went to the back to try it with some batteries and confirmed it was dead and that it rarely happens but that I would need to buy a new one. That is NOT acceptable for a device that costs £59.99

I am fuming to say the least.......

Any thoughts or suggestions on what I should do next (other than buying a new one)???
