While I am typing, my mouse disconnects. A few seconds later, and it has been as long as a full minute, it reconnects. Batteries are new. The mouse is about two feet from the iMac. Sure would like to know how to fix this.
iMac, Mac OS X (10.7.3)
Thanks for the link. It seemed to help but just as I clicked to get to this site the cursor/mouse disconnected again. I've done everything suggested by the link that you sent. I am at my wits end at this point. I'll keep trying to find out if there is something interfering with the signal. Do you by chance know where the antenna/receiver is on the iMac?
How long have you had this mouse. When did you last change the batteries. What was the state of the batteries you removed?
It may be that the terminals inside the battery compartment are soiled and need a thorough cleaning. Then do the same to the battery terminals because if the compartment terminals were soiled you could have contaminated the new batteries. While the batteries are out, it is also worth cleaning the sensor with a cotton bud dampened, but not wet, with white vinegar. Leave it to dry before reconnecting everything.
I think I have discovered the culprit. I had a metal ballpoint pen lying next to the mouse. I removed the pen and have not had the "connection lost" message since. I suspect it was blocking the signal or sapping some of the signal strength from the mouse. Thanks to all who helped.
Strangely had similar problems with metal pens on my desk with my older Magic Mouse. Interesting!
Well done.
Well Bryan, it only lasted for about half an hour. So then I decided to read all the above and seventy one suggested cleaning the contacts inside the mouse. When I looked at them closely with a flashlight I saw that they were pretty crummy. I cleaned them with a q tip and so far no problems. Time will tell.🙂
I have had this problem for 5 years. I have searched the internet for solutions, tried all sorts of things, even bought a new mouse. I have finally found the solution and it is so simple and why Apple couldn't actually supply this information I have no idea. Do not use Duracell batteries. They are, apparently, just marginally shorter than other brands - not enough to normally cause a problem, but with the magic mouse it causes lost connection. Since changing to another brand I have had no problems whatsoever.
I have found I need to clean the recessed terminal the positive end to the battery fits into a few times a year. A q-tip and a little isopropyl alcohol does the trick.
Amazing and makes perfect sense to me. I noticed as long as I treat the mouse with gentle movements, instead of rough movements, it doesn't disconnect much as it used to. After reading your solution...........the Duracell batteries inside, being marginally shorter, are moving around inside the mouse. Excellent catch Nelle96. Many thanks. I'll get non Duracell batteries tomorrow.
Yes! This was the problem. My students have this issue with their iClickers too. We advise them not to use Duracell batteries for the same reason. I should have thought of this!
I had this mouse for 4.75 years and this is in good condition. I used the Apple batteries to use my mouse to connect to my iMac 2011. These Apple Batteries were used to charge them on the charger. I had these rechargable batteries for just over 3 years.
