Yesterday my Magic Mouse stopped working. I tried several new batteries and it still won’t work. Can it be repaired?
Thats a good sign ;-} Try using a pencil eraser to clean the corrosion and/or non conductive film that has built up on the contacts. A cotton swab slightly moist with white vinegar can also clean up any crust from your alkaline batteries. Be sure to wipe down the area afterwards with some cotton swabs moistened with straight water (not to wet) to clean off the vinegar afterwards.
Changing from duracell batteries to energizer is the only difference in making the mouse I have work again.
I thought I’d post here for once, because my experience was different… I tried all the cleaning tricks after all the other battery troubleshooting, and still no green light. At all. Just quit, went dormant or something. I decided to delete the mouse from my Windows o/s, and just put the mouse aside; kind of clicked it and checked the light several times a day, nothing. Then, three DAYS later, I checked again and the green light came on, once. Baffled, I decided to re-pair to my o/s, clicked and clicked, and voila! It started working again. Perfectly. Perhaps it just needed a vacation! It’s a very heavily used mouse, first generation Magic Mouse. Baffling.
If you use a nail file gently it should work. Make sure the contact point is smooth and cleaned off. I used the cotton swab at first with alcohol and it didn’t work.
