Please advise-Battery charging/calculating????

I just realized that my Macbook keeps switching from "charging" to "Calculating" when the power cord is plugged in and won't sustain a full charge. I noticed this happened briefly once before but corrected itself and has not happened again until now. Should I be worried? any advice?

Robert,
My MacBook is currently at Apple's mail-in repair center in Memphis for this exact problem. They sent me a replacement AC adapter, but that didn't solve the problem. I'll be posting what I find out in the thread I started earlier:
http://discussions.apple.com/thread.jspa?threadID=897360&tstart=0
My suggestion is that you get in touch with an Apple Store, authorized repair center, or the AppleCare phone number as soon as you can spare the time. Although it didn't seem to affect the performance of my MacBook at the time, I am wary of letting the problem grow to the point that the battery's capacity shrinks or (worse) there's a short in the battery or adapter. Good luck!

  • HT201401 Hi.. My Iphone acts as if it is dead. Tried a lot with Sleep +home buttons as well, but did not worked. When it is plugged in, keeps on charging with a regular beep. Please advise.

    Hi.. My Iphone acts as if it is dead. Tried a lot with Sleep +home buttons as well, but did not worked. When it is plugged in, keeps on charging with a regular beep. Please advise.

    Yes, I understand that. But The screen issue is not a result of user damage. The phone was not dropped when the screen got cracked. My daughter was standing in a chair at the table and dropped one of her toys onto the bottom of the phone and cracked it right by the home button. (Nowhere near the LCD/digitizer flex cables, connections, or logic board components) then a few months later my phone had died, I plugged it in, it showed it was charging, then Apple logo disappeared and screen didn't work. AFTER contacting Apple about the issue and them telling me that it "is a result of the very minimal crack to the sheet of glass that has no relation to the LCD or Digitizer and that the warranty does not cover it I had taken it upon myself to change the LCD/digitizer to no avail, as well as backlight ic and backlight coil to no avail. But how do I go about letting Apple know that it is in fact NOT due to the cracked screen nor is it due to the flex cable connections? I can't. So the lady that works the call center phones  trying to "convince" me that she knows what she is talking about and "convince" me that it is from the cracked screen I have to take her word because I can't show Apple that its not because of that without paying them $199 to fix the screen in which case they will just send me a new phone rather than fix the faulty hardware under warranty.

  • HT1904 I have unauthorized charges to itunes store currently in dispute please advise.

    I have unauthorized charges to itunes store,please advise.

    Settings > General > Reset > Reset Network Settings.
    Power cycle the router.
    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.

    3gs reboots after 4mins on calls and shows battery dead then shows battery charged on restart any 1 have a fix please

    Thought it had worked but soon found out it had not.
    after further days of trying finally, solved it for me Yesterday.
    turned off notifications when locked, and bingo, wow.
    i have not turned off iCloud but location services are also off.
    best thing to do I found was keep checking your usage, settings, general, usage, and flip down to bottom, if the standby and usage are similar there is a problem, if there is a big difference then all is ok. Just keep turning things off and on until the difference is very apparent.
    something on my phone was keeping the phone alive even when turned off, and I think this was the phone repeatedly trying to update continually.
    to me this is definitely down to the iOS, my wife has exactly same phone and iOS but hers doesn't have any problem and the battery lasts for days.
    the guy at the Genius Bar told me to restore the phone via iTunes, not iCloud. This is because iCloud remembers the exact info from your phone and simply reinstates it when you restore, and this includes the iOS too.
    when I get home from holidays that's what I'll do, or wait for iOS 8 in few weeks. But I'm so pleased I finally made it work, I was beginning to think ditch the phone and buy Samsung.
    anyway anyone out there please try my final solution and let me know if it works for you?

  • Another New User, Please Advise, Can I Permanently Use Zen Stone From Power Adap

    Can I permanently run my new Zen Stone directly from the Zen USB Power Adapter. Like I have my Zen Stone connected to small speakers and would like it to run off the Zen Power Adapter (wall charger) not the battery, permanently. In other words I would like to keep it plugged into the Power Adapter all the time and run it that way so I don't have to run it off the battery and keep charging it. Is this OK to do Please advise this senior citizen trying to keep up with all this great stuff.

  • Zen V Plus - EXTERMELY URGENT help needed on battery charg

    Hi,
    I just bought a Zen V Plus 2 days ago. When I charged it for the first time for 6 hours (as instructed in the manual book), it was fine (fully charged in 6 hours). But when I played it, the battery life lasted for only about 7 hours listenning to mp3s (which is lower than it is supposed to be). Then I was told that a Creative Uni'versal Power Adapter will get the V Plus charged faster, and so I bought it. BUT HOW COME I HAVE BEEN CHARGING THE V PLUS USING THE WALL ADAPTER FOR 0 HOURS AND IT IS STILL NOT FULLY CHARGED YET??Please help me, how much longer do I have to wait for my V plus to fully charged? Does my player charging condition above means that my player is faulty?Please advise ideally how long should I charge the player if I use the USB, and if I use the wall adapter, to keep my battery long-lasting?Thank you.

    The wall adapter that I bought is the Creative Uni'versal Power Adapter for the Zen Micro (which I believe should also works for Zen V Plus). As I couldn't any longer after that 0 hours, I unplugged it. When later at night, I connect it to my computer, and it showed being fully charged for a few minutes, then flashes back to being in charge. (Is this normal?)?I used the player to listen to an album (about hour 20 minutes) and the battery indicator showed that it used up /5 of the battery life (which I think the battery life is too short). Hopefully someone can advise me what should I do to improve my battery performance?

  • Battery Charge on 2013 MBPr 15

    Regarding to some posts;
    a. To maintain a healthy battery on my newly purchased MBPr 15 inch, I am to drain the battery to around 20% before charing it again. Since this will minimize the no. of charge cycles the batter will have to undergo. It is very bad to leave the charger on after your mac's battery hits 100% since it will do something like a trickle charge. (continuously charging your battery once it drains 1% 99<->100)
    b. The new MPBr chargers are using new technology which does not trickle charge the Mac. Therefore, even if i leave the charger on after fully charging my battery, it would not damage the battery. (With that being said, it is still healthy for the battery if i unplug it and do a complete drain down to like 5%)
    Just wanted to clarify which is the best way to protect my battery. Which one is more accurate?
    Aside from school, this macbook pro will be used somewhere close to outlets most of the time. Please let me know what's the best way to maintain the health of my battery.

    Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
    http://www.apple.com/batteries/notebooks.html
    "Apple does not recommend leaving your portable plugged in all the time."
    General rule to remember of Lithium batteries is:
    Never drain them LOW  & dont always/often store them HIGH
    While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
    *A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge. 
    DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count.  *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                              (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
    *Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
    *However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
    Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                        This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
    LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
    A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
    Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
    The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
    Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
    Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.

    Storing your MacBook
    If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
    Considerations:
    Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
    In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
    Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
    Ultimately counting charge cycles is of little importance.  Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery. 
    Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
    Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
    Peace
    some usefull, partially "ok, interesting" information on same
    Gaming: In cases of heavy and frequent use in gaming it is recommended, if possible, to keep your Mac plugged in since these frequent fast and deep discharges of the battery are not ideal for battery longevity.
    If you were to always keep your macbook battery floating between 20% and 80% charge roughly, then you’d have no other considerations to make about your battery and its care,… except for long-term storage.
    Natural changes of capacity in lithium batteries happens when they undergo cathode degradation at roughly 20% per year where Ion exchange becomes less efficient. Mostly low draining (deep DOD) and to a much lesser degree high standing charge rates accelerate this process. Unnatural capacity for lithium battery charges changes, and chemistry changes in a lithium battery when often pushed or pulled to extremes
    In a lithium battery, deep discharges alter the chemistry of the anode to take up lithium ions and slowly damages the batteries capacity for the cathode to transport lithium ions to the anode when charging, thereby reducing max charge levels in mAh. In short, radical swings of power to lithium cells disrupts the chemical ecosystem of the battery to hold charges correctly which likewise impedes the perfect transfer of lithium ions both in charging and discharging.  In charging your lithium battery, lithium ions are “pushed uphill” (hard) to the anode, and discharged “downhill” (easy) to the cathode when on battery power. Deep discharges, damages this “upward” electrolyte chemistry for the battery to maintain a healthy charge and discharge balance relative to its age and cycles.
    Optimally, in terms of a healthy lithium battery and its condition, it is most happy at 50% between extremes, which is why low-power-drain processors such as the Haswell are ideal on lithium battery health since a partially charged battery with a low-drain processor has, in general, much more usage in hours
    Battery calibration, battery memory, battery overcharging, battery training, …all these concepts are mostly holdovers from much older battery technology, and on older Apple portable Macbooks ranging from early nicads, NiMh and otherwise; and these practices do not apply to your lithium battery and its smart controllers.
    Calibrating the battery on older Apple portable Macbooks with removable batteries.

    There is no calibration of current Apple portable Macbooks with built-in batteries.
    http://support.apple.com/kb/ht1490
    There is no battery calibration with current Apple portable Macbooks with built-in batteries. Lithium batteries have essentially a 0-‘memory’, and all such calibration involve the estimations fed to the system controller on the SOC (state of charge) of the battery over long periods of time as the battery degrades. The software based battery controller knows the battery's characteristics, or SOC and adjusts itself. This is why there is both no need and purpose to periodically deeply drain your macbook battery, since it doesn’t affect the characteristics of the battery, and further still deep discharges are something you should not do on purpose to any lithium battery.

    Bad discharging or battery use conditions:
    Heat (due to environmental conditions or due to rapid discharges from heavy use = gaming / video editing)
    Rapid discharging of the battery frequently causes chemical changes over time in the battery leading to decreased capacity and resistance of current flow.
    The very worst use of your battery is often draining the battery very low, and worse still letting it remain in such a state.
    *Most long-term rapid damage to the battery occurs from discharging it with high loading (gaming) conditions but paramount is avoiding deep and frequent low DOD (depths of discharge) in use.
    Undesirable charging or charged conditions:
    High perpetual SOC (state of charge), where the battery is always or very often connected to charge
    Parasitic loading where the battery is both usually on and charging or worse both always charging and in sleep mode, since this induces mini-cycling of the battery.
    Bad general handling conditions:
    Temperature use conditions when either too hot (95F and above) or too cold (50F and below)
    Storing your battery away with a low charge (40% and less) long-term.

    Hi ldyazch,
    You will need to set it up as a new phone, not from a backup, first. Then, after setup is complete, go to Settings > General > Software Update. Make sure you are connected to Wi-Fi and have at least 50% battery power. After then update downloads and installs, you can go to Settings > General > Reset > Erase All Content and Settings.
    This will let you go through the setup again, and this time you can choose your backup.

  • Random drop in battery charge while using plugged-in computer

    Hey everyone,
    I bought my Macbook Pro a couple weeks ago and have generally used it while it is plugged in. Recently I've noticed that while I am using it, the battery charge will suddenly drop from 100% to around 50-60% and the MagSafe adapter will change from green to amber and begin charging the battery until it reaches 100% again. I calibrated the battery the day that I got it and I have never had a problem like this until now. CoconutBattery even says that my battery capacity is more than 100% of what it should be. Please let me know if this is something I should worry about!

    I just noticed it happening again.
    very strange.
    AC Adapter connected and green
    icon in menu bar shows AC is connected, not charging.
    system profiler shows -1900 to -2500 mA
    system profiler shows Fully Charged: No
    system profiler shows Charging: No
    I am starting to suspect it's related to the ipad being connected, as that takes a good chunk of power to charge.
    I wonder if what's happening is that that with everything powered up on the macbook (External display, external Firewire hard drive, USB keyboard, Screen lit up, iPad connected) if it's somehow exceeding the capacity of the magsafe 85W power supply.
    to test this out,
    I've disconnected the ipad, firewire hard drive, and second display,
    done a SMB and PRAM reset
    and am charging the battery now.
    after that I'll do a calibrate and try to avoid connecting things for the next few days to see what happens.

  • How to Disable battery charging Function?

    Hi;
    I have a question about charging funtion of my "HP Compaq Business Notebook, 6720s":
    How can I disable "battery charging" function in windows 7? Is there any "advanced setting change" or "software"  that while battery is in its slot, stop my notebook from charging its battery?
    Thanks

    After some days trying many methods, yet I haven't find a solution to my problem. Then I ask is there  any one
    knows which software should I download for HP Compaq Power Management (similar to the software that Huffer
    mentioned, but that was for Lenovo) or which registery or BIOS change should I do , so that I can manually disable
    charging function of laptop, or at least put a starting level that up to that level, laptop won't start
    autolatically to charge battery, because in this manner once that my Battery reaches to below 100%, instantly begin
    to be charged & it would decrease its life time. Please consider that because of my power cable is to some damaged, sometimes it suddenly disrubt & cause my laptop abruptly shut down, then necessarily the battery would always be connected tob prevent this suddent effect.
    If any one could help me, I would appreciate him a lot.
    Regards
