Low battery warning for my iMac keyboard

I keep getting a low battery warning for my iMac keyboard even when it has brand new batteries. Is there a way to switch this off or reset it so that it doesn't keep informing me?

Hello! I also have this problem. My keyboard is brand new and so also the batteries. I have tried with different types of batteries but get the same warning. I also have tried to erase the device in the bluetooth settings and add it again. Nothing works. It is a pity because I like mac.

  • I just got a "low battery warning" on my iMac... What is that all about???

    Just got a low battery warning on my screen. What does it mean? What do I have to do to correct this? Could this be why it seems to take so long for pages to refresh/display; why the screen seems to frequently freeze and why I frequently see that spinning rainbow wheel?

    Your pram battery probably needs renewing.

  • Low battery warning for  low signal?

    Every once and while I get the screen showing the battery at red and asking to plug the Iphone in. When I looked at the battery life it's still had more than 30%, but my signal was on like 1 bar, could this be a reason why the Iphone might show a low battery warning?

    I've seen this before, and believe it's a Bug:

  • How do I turn off the low battery alert for my wireless keyboard?

    The question is in the subject line. I find it kind of annoying to have to keep closing the alert window, and am still able to use the keyboard for a while past when the low battery alerts began. I tried system preferences for both alerts and for the keyboard but am not seeing how to adjust it there. Any help is appreciated! And yes I understand changing the batteries would probably help but I am comfortable using the full life of the batteries rather than changing them out right away.

    Edit: Oh I found a possible, but drastic solution: disable the whole notification centre:

    I haven't tested this long enough to know if it helps yet, but it is easy to turn on again. I am so annoyed with not being able to disable these warnings that I am more than happy to disable the whole notification centre, if that is what Apple wants us to do to sort this annoyance.

  • Why does "low battery" warning always come up when I start the iMac?

    I've been getting a "low battery" warning lately when I turn on my computer. I've tried 3 sets of new AA batteries (bought from 3 different stores), but that doesn't seem to help. Of course it could be caused by the unlikely event that all three "new" battery packs were not fresh, but that's unlikely.

    and you're talking about the mouse ... the keyboard ... ?
    also, does the message vanish after a while? what does the battery indicator say?

  • 9300i low battery warning?

    After using an iPAQ phone for about a year I have bought a 9300i as an upgrade from my previous 9300 to get the great keyboard back, plus the iPAQ was awful as a phone.
    The 9300 had a very clear low battery warning, but I am not getting any sound from the 9300i. I have checked this forum's posts about it and have turned on all the notification sounds in the current Profile (though I couldn't see an option for Warning tones) and still no joy.
    Anyone know where I can turn this on, or is it a fault?
    Thanks!

    I keep getting a low battery warning when I start up my laptop.  
    I usually have it plugged in when I use the laptop.
    It is saying I might need to replace the battery.  Has anyone else had this problem?

  • Macbook no longer "sleeps" after 'low battery' warning, just suddenly dies

    My macbook (just over a year old) used to give me a warning with 10 minutes left that it would sleep so as my data was not lost, if I didn't plug it in. However, recently, it has stopped doing this - instead of sleeping, if I don't get to a power source in time within 10 minutes, it simply cuts out, with the sound of the hard drive stopping - like if you shut down a frozen macbook with the power button.
    This is REALLY irritating - what's going on? Why does it not sleep anymore, and is there any way to fix it?
    I'm on Tiger 10.4.11, with an intel macbook...

    Same Problem here. Tried several calibrations, smc and pram zap (well i guess there is no pram any longer so it zaps something else). Now I found another post where they talk about the battry 1.2 update. http://discussions.apple.com/thread.jspa?threadID=1449128&tstart=60
    I remember when trying to do an battery update to 1.3 manually the update told me that it is not for my macbook. But - I found the 1.3 update Bundle in /System/Library/Configuration/BatteryUpdater.bundle
    1. I Removed /System/Library/Configuration/BatteryUpdater.bundle from my system
    2. rebooted
    3. Emptied trash
    4. Installed update 1.2 by Softwarupdate.
    I will now do an SMC reset an then let the battery run low and watch what happens.
    Then do a calibration.
    I have the problem here in different ways. Sometimes Macbook shuts down suddenly after low battery warning, sometimes it sleep, almost never it hibernates.
    My Battery was replace after showing the x symptome about a year ago but now it looks bad again

  • No low battery warning on new Macbook Pro (Mid 2012)

    Hello!
    I just purchased my macbook pro this saturday and it's my first mac. I've noticed that I do not receive a low battery warning at all. What can I do about this?

    Thanks for the battery info, but the steps for calibrating the battery don't apply to current laptop models.

    Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article.

  • No "Low Battery" warning on new (November 07) MacBook - Kernel Panic

    Hello,
    I'm not sure is this is the right forum for this, but since the problem occurs during a specific battery state, I'm going to post it here.
    I just got one of the new November 07 MacBooks. The machine is great, and screams with the pre-installed Leopard.
    First thing I did was plug it in to charge as I started configuring software. Once it was fully charged, I pulled the plug, and began using it on battery. My plan was to calibrate the battery, by running it all the way until it forced a sleep, then shutting down and plugging it in again, as Apple recommends.
    Problem is, I never got the "Low Battery" warning, or even the sleep warning. At around 10 minutes of power left, I simply got a kernel panic. A few seconds later, the laptop just switched off.
    I plugged in again for a few minutes, then ran it down again to see if I could reproduce the error, and I did get the low battery warning.
    The next time the battery ran down, it gave me the kernel panic.
    Is this happening to anyone else? Is it a new MacBook problem, or a leopard power management problem? I'm having no other issues at all with the MacBook or Leopard. Any help would be appreciated.
    Thanks!

    I'm a little hesitant to force a firmware update on a MacBook it wasn't meant for. These are brand new models, and I would think Apple didn't ship them with the known faulty batteries or bad firmware.
    The frustrating thing is I have no way of knowing who the culprit is. Is it the brand new OS that I'm sure has a fair share of bugs? Is it the new hardware having a power control issue? Or is it a combination of Leopard and the new hardware? I was hoping to find some users who had the same problem so I could narrow it down. Battery drains out, kernel panic, then the machine shuts off after a few seconds. Funny thing is, the indicator says I have like 10 minutes or so left, but it appears that the battery must be completely dead, since it forces a panic and the machine just dies. So it might be a calibration error. The Mac thinks it has some juice, but in reality it's just about dead.
    I made an appointment for the Apple store tomorrow, so we'll see what they have to say. It's otherwise running beautifully, thankfully.

  • Leopard's Low Battery Warning on iBook

    Hey everyone,
    I recently upgraded my iBook G4 to Leopard. Everything works fine until I run the battery down low. When the low battery warning pops up, it either causes a spinning pinwheel or just appears as a white rectangle with a shadow. Then, after slowing down my Mac for a few seconds, the warning window disappears and the airport and battery icons in my menu bar disappear. A few seconds more, and warning and the icons reappear. The only way for me to stop this cycle is to plug in the adapter.
    Help!
    Matt

    Turns out I was having more problems than just the indicator... after replacing my power adapter everything worked fine.

  • N97 Low Battery Warning

    Is there a way to manually discharge the battery on an N97? Or alter the time between getting the first low battery warning and complete battery discharge?
      From the first time I get the warning to actual discharge takes ages.Yes that can be a good thing but if, like me, you prefer to let the battery completely discharge it can be like waiting for Christmas.
    I know I can use the music player, camera, video etc to help discharge the battery. But is there a more specific and faster way?

    You should not let the battery discharge completely. It can damage the battery. The battery prefere to have as much juice as possible on it all the time. Once a month you could discharge it to like 10-20 percent.

  • Low battery warning percent fixed??

    I have Vaio VPCYB15AG with Win 7 Ultimate SP1 32Bit retail. In it's advanced power options even though I can set percentage value for Low battery warning, I find that the warning is given (Blinking green power LED) when battery falls to 12%.Is this level kind of hard wired into the product or will it be a software / hardware bug?Thanks 

     
    Hi mmp_2013, 
    Thank you for considering Sony Community! 
    If the LED or the light indicator is blinking, then something is going on with the battery. It could be hardware but we cannot tell right away. Please follow the steps here to isolate your issue: 
    Check the battery health on Vaio Care (Desktop) - If indicated as "critical" then it already hardware issue 
    Power cycle - Remove the battery and all peripherals -> press and hold the power button for 5 seconds OR, if the battery is not removable, remove all peripherals-> look for a battery off button on the bottom of the laptop -> push the button for 5 seconds -> you may use a safety pin if you see a pinhole.
    Reset BIOS - Turn off the unit -> press and power button and immediately, keep hitting F2 key. Once in BIOS, go to Exit tab -> Get Default Values -> hit Enter -> Save changes and exit. 
    Download or update Sony® Shared Library, Sony® Firmware Extension Parser Device Driver, BIOS Update Utility from Sony's website based on your location or from where you purchase the laptop. 
    Your Vaio VPCYB15AG is an Asia-Pacific model and we have limited information about your unit. 
    For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
    Hope these help.

  • Low Battery warning at 90%

    I have a G4 ibook, that didn't get used for a long time, (over a year) and  I am using again after my newer laptop was stolen. The battery may be near the end of it's life, but I am confused by getting a "low battery warning" dialog box, when the battery indicator says 90%.
    If it was just dropping quickly I'd assume the battery was toast, but I don't get the conflict between the two pieces of information.
    Is there any point in resetting the PMU? Should I just consider this a not-so-portable until I replace it?

    Have you tried calibrating the battery?

    If that doesn't help, resetting the PMU may not help, but it wouldn't hurt.

  • Low battery warning when battery full

    This only happened to me this one time, but I have my iphone plugged in and the battery icon says it is fully charged, but I received a "low battery" warning.
    Any thoughts as to why this may have happened?
    Thanks!

    What version of firmware are you on? There were battery gauge problems in 3.1.2 that 3.1.3 is supposed to fix. Meanwhile, you can try running the battery down until the phone shuts off, then plug in to the wall charger for 4 hours. Do this twice. if it still doesn't work right you may have a bad battery; take it to Apple.
