Magic mouse 0% battery level - But batteries are new!

I just received my Magic Mouse today. It paired fine,connected fine and worked fine until I downloaded the software. Then the tracking became extremely slow and jerky. Tthe worst part is that the Battery level says 0% and I keep getting a pop-up window telling me the battery level is low - But I'm using brand new batteries??? I even tried several sets.
Can anyone help? I'm on a Mac Pro with Leopard.

Hello t:
Try trashing a preference file (com.apple.bluetooth.plist) and restarting. Then delete the mouse, restart, and then add it back in.

Hi i;m using macbook pro . magic mouse pointer not moving, but do all the rest of things

hi i;m using macbook pro . magic mouse pointer not moving, but do all the rest of things

thank you, i have tried you suggestion but it is still just prompting me to restart rather than allowing me to install the os from the os boot disk. the problem began when the macbook was just showing me a folder icon with a question mark on it rather than starting normally. reading through forums lead me to replace the hard drive and hard drive data cable to try and resolve the issue. however, even after having done this the folder with the question mark is still appearing. i cannot get the os istall disk to boot properly. it recognises that the disk is in the drive but continually prompts me to restart and wont allow me to boot from the disk. sorry if my previouse discription wasnt accurate. does this soun familliar and can you help with this more detailed discription of the problem? thank you.

Why does magic mouse not work with duracel batteries

I bought an iMac a few months ago.
Now the batteries from the magic mouse are empty and I had to buy new ones.
Only they don't work. I had to pick cheap batteries from others devices.
Can anyone tell me which brand wil work?
Thanks,
Bernadette

I bought my iMac 2 years ago, it came with a Magic Mouse, within several months I started having the same battery issues. I looked here, and on the Internet to find out if the problem was already known about, but found only people guessing wrongly at what the problem is. I do hope Apple has fixed this, but unfortunately many of got stuck with a junk Magic Mouse. As an Engineer with 25+ years of experience in the design of electrical contacts & connectors which includes over 2 dozen patents ... believe me when I say the problem here is that the recessed positive contacts (at the on/off switch end) are too deeply recessed to make contact with the industry allowed variation in AA batteries. Those contacts are too deeply recessed because the plastic is too thick (in the hole that forms the recess) and the metal contacts are not tightly up against the backside of that plastic wall, in fact it looks like they are installed with a gap and/or can deform/bend away further opening that gap even larger. As mentioned above many industry AA battery standards define the positive button contact height as being 1.0mm or larger ... however that plastic wall is about 1mm thick, add the gap for the metal contacts and you have no electrical contact no matter how much contact spring force there is at the negative end. Unfortunately, there is no simple good fix for the average person to perform, the recessed contacts can't be accessed to bend them to remove that gap and the pastic is too thick anyway .. leaving us with a "duct tape" fix, like wadding some tin foil into that positive terminal recess and swearing when it falls out during battery changes. A nice elegent fix, would involve disassembling the mouse, machining plastic, backing up those terminals... absurd right?... would be easier if Apple sent us a new mouse that works.
This problem has nothing to do with overall battery length, battery diameter, or inadequate spring contact force from the negative mouse contacts. Also I doubt the brand or type of battery is the issue for anyone, the positive button heights vary among brands/types, but probably are 1.0mm or larger per the industry specs, Apple just didn't design this mouse to that industry spec, or they did not control their manufacturing quality to yield what they designed. This iMac was my FIRST Apple purchase after decades of avoiding and dismissing Apple, ironically they won me over with their progress and high quality products ... I'm rather disappointed.

Magic Mouse glitchy behaviour with Apple batteries

Hi,
Since the Magic Mouse has a voracious appetite for batteries, I bought the Apple charger with the included batteries.
For the last month, everytime I use this Apple batteries, the Magic Mouse starts behaving erraticaly (mixes up right and left click), no scrolling, etc.
As soon as I switch for regular batteries, all these problems are gone.
I knew the Magic Mouse was sensitive to batteries voltage differences, but I wasn't expecting this from fully charged Apple batteries.
Does anyone know how to fix this, apart from using other batteries? Does anyone experienced something similar?
Thanks in advance,
Jorge

Never heard of that from new batteries.   Here are some notes I've written about batteries.
Whether you use regular or rechargeable batteries you should buy the best. Discounted or unbranded batteries are more likely to give a depleted performance and may be of irregular size, often leading to connection problems. Apple’s own brand, Eneloop and Energiser appear to be the best.
Rechargeable batteries for the standard Magic mouse are unlikely to exceed eighteen days before needing a recharge although the mouse itself can be a limiting factor.   I have seen reports that some Logitech mice vastly exceed this.   Apple may suggest more in their sales blurb but this is a realistic expectation.   The benefit (if you are organised) is that you can always have charged batteries available.   Regular batteries will give you between 25 and 35 days before they need to be replaced.
Note. Never mix old and new batteries or rechargeable and regular.
Both the above are based on my personal experience, not shutting down my machine and using it for around four hours per day.   Note.   Monitors do not always faithfully report battery strength, particularly with rechargeable ones.
When checking your mouse or keyboard batteries ...
Turn off the device.
Remove the batteries,
Clean the terminals both inside the battery compartment and on the batteries themselves.
Replace or renew both batteries.
Turn on the device.   You should get a blinking green light if the device is paired.
Click the mouse to activate it. The green light becomes steady.

Magic Mouse not working with rechargeable batteries

Hello,
I have a Magic Mouse. I ran out of alkaline batteries and replaced them with Philips rechargeable batteries.
Magic Mouse refuses to turn on.
The same batteries, used in a MS Mouse work just fine. In fact, it works even with only one of them.
Are there incompatible batteries with Magic Mouse? Can anyone advise?
Thank you.

I suspect it may be a voltage issue. Virtually all rechargeables work in my Mighty Mouse but I have not been able to get rechargeables to work at all in my Magic Trackpad. I have tried about 5 different varieties. What I have not tried, as I did not have any with me in France, are these "instant on/ready to use" rechargeables. I measured the voltage of newly recharged NiMh cells at about 1.47V, which quite quickly dropped to about 1.3 to 1.4V and then stayed there a long time. Fresh Alkaline were about 1.6 to 1.8V and fresh Oxyride or Lithium, about the same. For high current devices, the lower voltage of the NiMh cells may not be an issue, as their internal resistance is much lower than alkaline, so that the effective voltage in use may the same. However for very low current devices like Mice or trackpads, the free voltage may be more important,

Magic Mouse - excessive battery drain

I love the design and the flexibility of the new Magic Mouse! It's a next generation mouse!
However, I would really like a wired version. The battery life is not acceptable for me. I am a heavy user (up to 16 hrs a day) and it works only up to two weeks if I don't turn it off/on all the time. I don't want just another thing to worry about. Also, it's too heavy because of batteries inside... and the side buttons should be there, they'll fit in the design nicely...
Also, The Better Touch tool and similar utilities should be in the OS by default. Ahh.. I guess I'll be back on my good old wired Mighty Mouse after all the excitement...
Any advice on what batteries to use? Is there some third-party kit to convert Magic Mouse into the normal wired mouse?

Here's 48 batteries for $8.54. I think that should keep you going for awhile.

I've had mine for 3 weeks exactly and my mouse is at 55%. Then again I'm only on a couple of hours a day. 16 hours a day is more then I might be on in a week. In my G5 I used a Microsoft mouse that had a cradle. I loved it but I love this one more. I understand your pain but I can't imagine Apple ever thought anyone would use this mouse for 16 hours a day.I agree a cradle would be a great idea but Apple is into simplicity not a cradle with a wire ruining the esthetic look of the new iMac.

Magic Mouse Heavy Battery Use.

Hello. I seem to be getting poor battery performance from my Apple Magic Mouse.
Last couple times have been about 1 month each--doesnt seem that good to me and a bit of a pain. Any comments? Maybe I should be turning it off at night? Thanks for any info.

Another good idea is to set your computer to sleep after a certain amount of time. If your computer is on constantly, your bluetooth mouse/keyboard will be on as well. If your computer goes to sleep after 15 minutes, or an hour, or whatever works the best for you, you'll conserve battery life.
My computer sleeps after a half hour of inactivity, and I get a couple of months of battery life on my keyboard and magic mouse.
I do have an apple battery charger, which is convenient, but any rechargeable batteries work fine.

Magic Mouse leaked battery fluid

Hello,
I have a Magic Mouse, bought with my MacBook Pro in February 2011. I didn't used the mouse so often and the battery charge was on 90% when I last used it.
Today I saw that the battery leaked and the mouse is full of something like white powder. I never changed the batteries, I just used the original delivered Energizer.
I always turned off the mouse when it wasn't in use.
My question is, can I send the mouse to the repair center and get a new one for free? I also can't check the serial number online.

Hello:
The short answer to your question is no. The mouse is out of warranty and it is your responsibility to assure that batteries are reasonably fresh.

Magic Mouse and battery life....

Well, today my Magic Mouse died...had to replace batteries. So I didn't get 3 weeks out of the original batteries....I received it on October 28...if this keeps up, I can see where the mouse will go on craigslist....very disappointed. Anyone else have to replace batteries already? I don't physically turn it off; the mighty mouse would automatically power down after period of no use....i'll try to power it off everytime I'm going to stop using it for awhile but there's no way this will work for me.....

Actually, the Magic Mouse is only for wireless keyboards and the extended keyboard is only available wired.
That's rubbish. I have a WIRED extended keyboard and a Magic Mouse. Which keyboard you use has absolutely nothing to do with which mouse you use.
Rechargable batteries have a lifespan and eventually end up in the waste stream like other batteries
After hundreds of uses. So instead of sending hundreds of batteries to the waste, you're only sending one. How can that not be better for the environment?
they don't have the power or charge life of a precharged disposable
As long as they have enough power to power the thing they're powering, what does it matter? And if they don't last as long (which is also bogus, just buy higher mAh ones) what does that matter? You just recharge them. Anybody who knows anything about environmental waste will tell you rechargeable batteries are better.
What would be the reason not to have a wired version Magic Mouse and what would be the reason not to have a wireless extended keyboard?
Once again - there is absolutely NOTHING stopping you from having both a wireless Magic Mouse and a wired extended keyboard.

I would like to AirPlay mirror my iMac and be able to use both my magic mouse and wireless keyboard, but the bluetooth range won't let me. Is there a way to extended its range?

I am buying an iMac to AirPlay mirror on my big screen TV with AppleTV (2nd generation). But my TV is located far away from my iMac and I won't be able to use my magic mouse or wireless keyboard via bluetooth connection. I know I can use an app to simulate both mouse and keyboard, but I really need to use the actual devices.
I wish there was a way to pair them to my iPad or iPhone, via bluetooth, and control my iMac via network. It is a cheap solution, as I wouldn't need to buy any other device. I believe all these devices, without modifications, have enough technology to be able to work as I've imagined. The only need was to adapt the software.
Is there a solution simple as this one, or do I have to buy a Bluetooth extender in order to use my magic mouse and wireless keyboard? If so, which BT extender do you suggest and what is its range?
Thank you!

If you are still under warranty, contact Apple to get it serviced. You can also visit an Apple Store or Authorized Apple Service Provider to get it looked at.

How? Rediscover Magic Mouse following battery replacement?

Every time I replace batteries in my Magic Mouse I've had to access System Preferences | Mouse to activate the "rediscovery" process. Fortunately, I have a USB mouse that allows me to open, and then navigate, System Preferences.
Shouldn't my iMac automatically find the Magic Mouse?
Solutions?

Shouldn't my iMac automatically find the Magic Mouse?
Yes.
Solutions?
Clicking the mouse repetitively usually works. I would also make the mouse a favorite.

Magic Mouse 1 finger swipe moves app to new desktop

My mid-2009 is running the latest ML bits and it has developed an extremely irritating behavior.
When using my Magic Mouse a 1 finger swipe across the top part of a window moves it to the next desktop. I have my settings in system prefs set to use a 3 finger swipe to change desktops. I also have turned off "Swipe between pages" in the Magic Mouse settings. Sometimes I'll move my finger on the mouse a litlle and suddenly find myself (and the window I was over) on the next desktop.
I also get this behavior on my MBP pad if I swipe 2 fingers across the top of a window. That's also a little irritating, but less disruptive to my work.
I would love to know how to disable this behavior.

I guess you have installed all available updates, including this one?
http://support.apple.com/kb/HT3936
As a test, you can create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.6/en/8235.html
Log out and log in to the new account. Try the mouse there. This will help narrow down the cause. If it works in the new account, the cause is probably in your normal user account. If the same problem recurs, then the cause is probably at the system level.

TS3048 My wireless keyboard does not turn on. Yes batteries are new and installed correctly

I don't know why my wireless keyboard is not working. I can't sign onto my computer. Installed new batteries and yes they are installed correctly. I'm wondering if maybe it doesn't work anymore. It's only a couple of years old!

Hi, Mike.
Thank you for visiting Apple Support Communities.
I understand that your keyboard is not functioning. Here is a troubleshooting article that I would recommend going through for this.

How do i connect my keyboard when it is turned on and the batteries are new, the bluetooth does not recognize it?

I had a connection between my macbook pro and my wireless keyboard, when the keyboard stopped working. I replaced the batteries, and it will no longer allow me to connect the keyboard. In fact, my macbook no longer recognizes it at all when I try to reconnect via bluetooth.

Yes, I've had a similar problem:
My keyboard was connecting just fine except for recently when my son would switch to his user and then I would switch back after he finished his homework in another room in the house.
Now I've restarted and there is no longer a Bluetooth option to click in System Preferences, and as I dig deeper into the Network option, I can click the Bluetooth PAN, but if I try to "add" a BT device or select "Advanced" the button is grayed-out and the message says BT is not available.
The keyboard power cycles fine and is available to my iMac for pairing.
My top of the screen menu bar shows the BT symbol, but tells me it's not available. Whaaaat???
Utilities' System Info tells me there is "no information available" when I click the BT devices under hardware.
Somehow it appears I've either lost the BT drivers or the module has failed.
Any suggestions??
TIA, Bradley
