Magic Mouse won't turn on AT ALL.

I am so grateful for this post... I was seconds away from buying another one, then I read your post @initial Wesley, Thans fo MUCH!!!!!!

I'm having the same problem. Just tried some new Ray-O-Vac's & the local grocery store brand, neither of which worked. In looking at the positive terminals, they are slightly shorter than the ones that are almost dead (cvs store brand.) I guess once you find a brand that works, stick with it. Still seems like something of a design flaw in the mouse that it is that finicky. Don't think I've ever had a similar problem.

Weird I use the energizer 2300mAh batts and they work great.. it was when I switched to Duracell that it didnt like it. Maybe its high time someone designed a rechargable battery pack which slots right in and likes the power mat 😀

I have put in a few different batteries and also tried every solution that people have surgested and still nothing. Shall I take it to the Genius Bar at the Apple Store? I think that its dead to he honest...

THANK YOU SO MUCH this post has saved me £40!

i was just about buy a new mouse this seach was my last attept to fix it!

cant believe it was just the fact its fussy about battery type, kodak are a no no!

I had the same issue and noticed that some brands of batteries don't quite make contact as the positive end of the battery doesn't stick out enough to reach the contact 😀

I took mine back several times before I twigged LOL

I can't believe that this mouse is so sensitive. I had the same issue where I put in fresh batteries and no green light. Lo and behold, I had put in a different brand. My mouse does not like DURACELL. I swapped them with ENERGIZER and bam! My mouse LOVES ENERGIZER. Green light, good to go. So check your battery brands and get the ones that this little picky mouse likes! Thank goodness I came across these posts or I would have been out buying yet another $70 piece of mouse.

Thanks to DeathCubeKX for the original post and to all who responded. My mouse wouldn't turn on with Duracell batteries (nor with little pieces of aluminum foil added to the positive end). After reading these posts, I ran down to the local pharmacy and bought some Energizer batteries, and now the mouse works like new.

I don't actually know how my magic mouse started working. One fine day when I came back from home, turn on my mac and my mouse, the mouse won't start all all. I subcribed to this post to try out the suggestions but nothing ever worked. Duracells definately didn't work. I took my mouse to the apple store and showed it to them and they suggested that I buy Apple's chargable battery, fortunately and unfortunately I fell short of $5 and couldn't buy the batteries.

I went home and deceided to get it one more try, I took the new kinds of duracells (the one with the power meter) adn plugged them in and voila! It work, not only did my mouse started working, it lasted for nearly 1 and half months. Considering I use my mouse everyday.

Try to get those duracells witht the funky 'power meter' the one your press and it shows you the amount of energy left. I think their slightly bigger and more powerful, so their a perfect match for the mouse.

🙂 Hope this helps. 😉

I spoke too soon. The new batteries only lasted about an hour. When I left the mouse alone, and returned, it didn't ever come back on. I will go out an buy yet another brand/kind of battery. This is getting ridiculous. Thanks for everyone's posts.

I had the same issue...tried different batteries, regular, rechargeables, etc... until I decide to shine a flashlight into the battery compartment...

Check the positive end of the batteries connector. With time, some residue will build up, reducing the contact zone...

a bit of Isopropyl alcohol on a cotton swap, rub it against the connectors, voila... clean connection again...

Cheers

Thanks for posting. You saved me an hour drive to the local Apple store. 🙂 It turns out this was the issue I was having. Duracells do seem to have shorter positive terminal height above the battery top shoulder than the CVS store brand I had been using, and when I put in new Duracells, the mouse wouldn't power up. The fix was to fold some aluminum foil several times and cut off 2 little squares and place this on the negative terminal side. This gives enough added length to force the positive terminals up into the holes far enough to contact the pads inside the mouse. This is really a glaring design flaw on the part of Apple, if you ask me.

Hello,

I am here for the same reason, but I also figured it out as well. many people are right, the Magic Mouse, I have noticed today that it does not like Rayovac, or Duracell. But I found that Energizers and Eveready batteries work fine, I found the same issue, that the positive tip on the batteries that didnt work were shorter than the others. This could be because after using the ones with the longer tip caused the connection plate to be pushed back, causing no connection with the shorter ones, I use to be able to use Rayovac in my mouse. I did find a trick in how to get the Duracell batteries to work, in fact I am using them now after having to adjust their position within the mouse. To get Duracell to work, you must angle them the negative end closer to the bottom removable plate, and a lite tap may be required to get them to slide into place so they power the mouse.

I was thinking on using a couple small strips of aluminum foil folded and placed in the hole for the positive tips to ensure connection to the internal plate, I may still use that idea, if I continue to have an issue with different batteries.

I hope this has helped some, I was slightly annoyed when I noticed the issue.

I had the same problem too, having been turned off for a while, my mouse wasn't turning on and my green light wasn't lighting up or blinking, nomatter what batteries I used.

I removed the batteries, and saw there was some dried on battery fluid on the contact.

If you carefully scrape this off, and replace the batteries, it should work.

Also I've never had any problems with specific batteries - any AA batteries have worked for me in the past, alkaline and rechargeable.

Good luck!

I found a fix! Take some aluminum foil and make two squares. Put each piece of foil between the battery and the negative side of the battery compartment. Make sure that each piece of foil does not touch, or you'll complete the circuit! If you've done it right, you should see the green light turn on. If not, leave it how it is for a bit and then check to see if the batteries are warm. If so, make sure the two pieces of foil aren't touching. If the batteries are not warm, try getting some fresh batteries. I hope this helps! If you need further help, feel free to let me know! I've fixed tons of these.
