    It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate. You should calibrate your battery once a month. This keeps your battery healthy for when you need to use your MacBook portable.

  • Does it harm the battery if the macbook stays turned off for a few months?

    I might be in a situation where I will not use my macbook for a few months. A family member may use it occasionally, but it would be turned off most of the time. Does this hurt the battery or other aspects of computer performance?

    From the User Manual: "Storing your MacBook If you are going to store your MacBook for an extended period of time, keep it in a cool location (ideally, 71° F or 22° C) and discharge the battery to 50 percent. When storing your computer for longer than five months, discharge the battery to approximately 50 percent and then remove it from your MacBook. To maintain the capacity of the battery, recharge the battery to 50 percent every six months or so."

  • Does it harm the battery if we use the laptop while charging?

    If we use while charging, is the power required directly taken from the external supply or from the battery itself. Which is the safest way to use the laptop without drawing power from the battery?

    No harm is done. There is enough power from the adapter to run the laptop and charge the battery. There is hardware and software in place which prevents any problems. The laptop will not take power from the battery while the AC adapter is plugged in. 

  • How do I discharge (calibrate?) my Macbook Air (Mid 2013) without harming the battery?

    I just got the latest MacBook Air this week. And after reading the discussion here https://discussions.apple.com/message/22294118#22294118 I chose not to calibrate it the first time since it shouldn`t be necessary with lithium-based batteries.
    The thing that still confuses me about the calibration issue with the Macbook Air (Mid 2013) is the text I`ve underlined below from Apples page and where they are talking about lithium-based batteries:
    http://www.apple.com/batteries/notebooks.html
    "Standard Maintenance
    For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month. Need a reminder? Add an event to your desktop’s iCal. When your battery no longer holds sufficient charge to meet your needs, you may choose to replace it. If your notebook came with a built-in battery, you should have the battery replaced only by an Apple Authorized Service Provider."
    So when Apple is talking about discharging, how should I actually discharge it? If discharging a lithium-based battery completely is harmful for the battery life, then what is the ideal way to do this without harming the battery? How should I discharge my battery when the calender says it`s time?

    Calibration is not needed for "built-in" -non-removable- battery.
    "Portables with built-in batteries
    Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article. These computers use batteries that should be replaced only by an Apple Authorized Service Provider."

  • MIFI4620LE Jetpack blinking amber light--does this mean the battery is bad? Should the unit operate without the battery installed if plugged in?

    MIFI4620LE Jetpack blinking amber light--does this mean the battery is bad? Should the unit operate without the battery installed if plugged in?

    The MIFI4620LE Jetpack does not work without a battery installed, even when connected to an external power supply.
    I personally think that was a dumb design. I would think the unit would use more electricity when continually charging the battery than just powering the unit it's self, but that's the way Novatel made them.
    If your Jetpack works with the battery installed and connected to an external power supply, but does not power on with power supply disconnected, I would say that the battery is defective or worn out.
    You should be able to go to a nearby Verizon Store and have them either test the battery or put a new one in it to see if it works. Then you will know if you need to spend the $$ for a new battery. OR if you always use your Jetpack at home, or in your car, just use the old battery connect to a power supply or your cigarette lighter and save the cash.
    As the Customer Support person stated, the slow blinking amber light is a normal state when the Jetpack is turned on and connected to Verizon's service.
    I hope this solves your problem.

  • Does 4G drain the battery more than 3G with the iPhone 5?

    Hi im due an upgrade and im thinking about getting 4G, but does it drain the battery more than it does with 3G with the iPhone 5?

    the phone can handle it or else it wouldn't be supported. it can also handle LTE which is even faster than 4G in most cases

  • Power Adapter Does Not Charge the Battery and Charge Light Is On?

    Power Adapter Does Not Charge the Battery and Charge Light Is On?
    My power adapter doesn't charge my computer anymore. however the charge light is on.
    Please help my battery is draining fas

    So, with your power adaptor connected not only does the battery not charge but the powerbook is not running on ac power. Then I guess the power adaptor is faulty. In as much as you've verified this with a known good one a new one is in order. Try yours in another powerbook to make sure.

  • My new iPod nano does not get the battery life that is advertised

    Help me my iPod nano does not get the battery life that is advertised

    Which battery life are you referring to? Apple's website states the iPod Nano 6th Gen will get "up to 24 hours of music playback when fully charged". There are going to be a lot of things that can change that. Are you using the stopwatch or the count down timer a lot? Are you using the FM radio a lot? Any accessories that you are using with the iPod? These will all have an effect on your battery life.

  • Does it drain the battery to charge before completely empty?

    Does it drain the battery to charge before completely empty?

    No, actually draining the battery completely is worse for it. Batteries will only charge to what they need. You can see this for more answers. http://www.apple.com/batteries/

  • Satellite A100-166 PSAA9E does not charge the battery

    Hello,
    My laptop does not charge the battery.
    Although Windows Xp recognizes the battery and says charging, the battery is not recharged.
    I tried with a spare battery as i thought the battery was defective, with same results.
    Strange is, when i turn off the laptop the power supply led stays on and blue, even without the power supply atached thus discharging the battery.
    The battery led is always amber but not charging!!!
    What is the matter with the laptop?
    Thanks

    Hi
    Generally there are three different possibilities;
    1) the AC adaptor is faulty
    2) the battery is faulty
    3) the notebooks board electronic (power supply electronic) malfunctions
    So now its necessary to check all this steps to locate the fault.
    You said that you have tested different batteries and the AC adaptor works too.
    So its possible that there is something wrong with the power supply electronic
    In such case there is no much to do as to contact the ASP in your country. The technicians should check the notebook and should run some diagnostic tests
    I recommend contacting the guys and ask for the details and for the further handling Good luck and happy new year.

  • TS1367 My charger connects with my macbook with a very faint green light (not the normal orange light) and can maintain the computer turned on but does not charge the battery.

    My charger connects with my computer with a very faint green light (not the normal orange light) and can maintain the computer turned on but does not charge the battery. The power source to keep it on is the power adapter and that it's "Not charging" on the battery settings. And my charger seems to charge other computers fine.
    The part of my mac where the adapter (L-shaped, magnetic) attaches is a bit damaged - a small piece of the white case/body around the part where the adapter attaches is broken off, but that's just an outer damage.
    I don't know what's wrong with my computer, and if anyone has had a similar experience or knows what's going on, it'd be tremendously helpful!
    Thank you!!

    Hi Christopher,
    Doubtful an upgrade would fix a hardware issue. If you are thinking of upgarding to Lion, best to do all necessary maintenance first.
