Is my Magic Mouse Dead?

I had the same problem, no green light but conection was ok, touch ok, click ok.My warranty has expired and i open myself the Magic Mouse.I found sings of oxidation near a diode, the unused pin form the diode make conection with the anode of the diode.I cleen up the oxidation with alcohol isopropyl and now my magic mouse work again.

I'm sure this is an manufacturer defect.So if you have warranty, good for you.If not take a look inside your Magic Mouse.

Thank You!

Hi,

My Apple Wireless Magic Mouse does not track/move the cursor on screen, but it's connected to the iMac bluetooth. The batterys are full. I also replace them with new ones.

I can left-click, right-click, double-click, scroll and swipe with one/two fingers. You name it! Everything works, except I cannot move the cursor, it does not track at all.

I started having this problem when I went on vacation and turned the iMac off and also disconnected the power cable from the power socket for a couple of weeks. When I came back and turn it on, the Apple Wireless Mouse had this problem. But still, I could make it work if:

1) I remove the mouse from the Bluetooth Preferences list clicking the "-" (minus) button and then put it back on again in the Bluetooth Configuration Assistant.

2) After a while I noticed that after a restart I could click the mouse and I could just wait a while (3 to 5 minutes) and the mouse will start moving again, although the cursor would not track/move and behave as expected for 1 or 2 minutes (jittery, jumpy, slow, fast), but after that 1 or 2 minutes would eventually come back to normal.

The problem would return after I would Pause the iMac. After I wake him up again the Mouse was not moving again and I had to go trough the process described on step 1 or 2 to make it behave correctly again.

I think, in the beginning when I restarted the iMac in Safe Mode (keep pressing Shift in the restart process) the mouse would behave normal. So I thought that this was a software problem/conflict with some third party login files, etc. I deleted the LaunchAgents form the User Library. Didn't work. And also look inside the folder StartUpItems in the System Folder, but it was empty. But now, even if I restart in Safe Mode the mouse doesn't move. :-(

Also, I tried all of this without success:

Any ideas, please? I need help.

Thanks!

I had a Magic Mouse disfunction some time ago which was solved with the advice fro IB retired earlier in this thread as reported above. Having now suffered the issue or a similar one again I have collated all the various advice into a logical series of steps as follows:

Fixing unexpected behaviour of a Magic Mouse

(1) delete com.apple.bluetooth.plist in Library/Preferences

----

(2) Reset the tracking and lag for the magic mouse:

Open terminal and type in: defaults write -g com.apple.scaling (choose any number between 2 and 8)

Then you need a restart your mac and it should be sorted - so now take step (3).

----

(3) Resetting the SMC - on portables with a battery you should not remove on your own

Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

Shut down the computer.

Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time for 10 seconds.

Release all the keys and the power button at the same time.

Press the power button to turn on the computer.

..... Now you can take step (4) below if you wish ......

Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC

Move pointer over Bluetooth icon on menu at top right. Choose “Set up Bluetooth Device”. When window opens up turn off the mouse for 2 seconds and turn back on. Mouse should show up in window. Pair mouse.

If that does not help, delete the device, restart the computer, and let the assistant find it again.

----

(4) Reset the NVRAM / PRAM.

Shut down your Mac.

Locate the following keys on the keyboard:

Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.

Turn on the computer.

Press and hold the Command-Option-P-R keys before the gray screen appears.

Hold the keys down until the computer restarts and you hear the startup sound for the second time.

Release the keys.

----

(5) Bluetooth and wifi can conflict with each other because they both use the 2.4Ghz band. Another way to fix the problem is to change your Wifi to a lower channel like 1-3 or to change to the 5Ghz band.

Just to let you know, actually what worked to me was this:

Pretty simple but I never would have realized...

I know this is an old post, but for everyone searching for an answer, it can be as simple as just cleaning the battery contact points inside the mouse with a Q-tip and rubbing alcohol. Be sure to clean the contact points on the batteries before putting them back in, too. I found the tip here plus a few more ideas.
