MacBook Battery charger

I just brought a brand new battery charger for my macbook because the previouse stopped working ( it was less then a year old). The new one I recentaly brought a month ago just stopped working and smells of burning plastic at the transformer. Are they covered under the one warranty as well?

As far as I know, only the battery has a limited warranty. Anyway, bring them both back. In my opinion, it's ridiculous that a charger stops working within a year if you treated it well, and you should get free replacements. If you like, you can sell the spare on eBay.
It might be reassuring for you to know, that the MagSafe power adapter has a number of problems that are somewhat known:

  • MacBook Battery Charge Problem - With a Twist

    I got a white MacBook in October to replace an ailing iBook. It ran fine for almost five months, with a slight twist that I've been reticent to come on here and ask about.
    Problem #1: The battery charging had what I'd call frustrating behavior. The computer would not charge the battery unless I practically ran the battery down to nothing. Usually it wouldn't start charging until 20-30% charge. My old iBook would start charging at about 85%, so I just figured it was some failsafe that Apple was building in to the new system to improve long-term battery life. This frustration continued until today when...
    Problem #2: I went to a coffee shop to do some work. I'd forgotten the night before that I hadn't let my battery run down enough to charge it, so the battery was at 35%. Okfine. I'll run it for a few minutes and then plug it in. I wait. 30%, 25%, 20% and whenever I plug it in to test, it won't charge. I run it all the way down to the point where the system automatically goes to sleep. The battery won't charge. I've reset all the things that can be reset, I've reseated the battery, I've turned it off and back on, I let it sleep for an extra amount of time to squeeze that extra bit out of the battery. No beans. The thing refuses to charge.
    In system info, the battery information shows that it's completely dead (remaining power at zero across the board, not the negative numbers I've seen reported in other threads). The power information recognizes that it's a battery with 0% charge, but only says "Calculating until full..." Given that it won't charge, it's going to be calculating for a very long time. The battery flashes one light when I press the button.
    I'm going to take it in to an authorized service whatsit on Monday, but in the meantime, what is it likely to be? I've seen answers ranging from bad battery to faulty motherboard. Is there any step I've overlooked to try before resorting to a trip to the store?
    Thanks in advance.

    Yeah, if it says your battery is only at 18% of it's charge after just a few months, then there is definitely something wrong with it. They will probably give you a replacement battery, considering it is still under warranty. My iBook (2 Years Old) is down to 29% of it's original charge capacity, so I am in need of a new one myself :\
    2 Years is what Apple says is the average life span of a laptop battery.

  • MacBook battery charger light flashing

    The charger light on my Macbook flashes orange/green when fully charged. It goes to 100% then it turns green. A few seconds later the light turns to orange again. And it keeps going on like this ...
    I tried shutting it down, updating, removing the battery. What should I do?

    Have you tried resetting the PMU?

  • Black MacBook battery charger question.

    Can I use the charger from a 2009 MacBook Pro on a 2006 Black MacBook Pro?  I'm having trouble charging the battery on the MacBook and now think it might be the charger (I've already replaced the battery, reset the SMC, and run he battery update).  The specs on the chargers themselves are very nearly, but not quite identical.

    but my battery is still working fine
    I'll be you anything it's not. With that many cycles it's not uncommon for weird things to start happening regardless of how well it performs. I would look into getting a new battery as well.
    Have you reset the SMC?

  • Macbook Battery Charger Overheating

    Hey y'all, my charger for my black macbook overheats when I use it and it smells like something is burning inside. any ideas what may be causing this? Will it damage my computer?

    i would SERIOUSLY recommend you stop using it and give apple support a call, that can probably mess with your computer because if your charger is not working properly the circuit that keeps the voltage in a regular level for a computer might be affected and give your computer a high voltage and it could be the end of your laptop.

  • I bought Macbook Air early 2014. Ever since i bought it to turn it on after a long ie. 5hr - 6hr i have to first charge it for at least 15 mins and sometimes it wont turn on for 3hr - 4hr and then it will turn on regardless of the battery charged.

    I bought Macbook Air early 2014. Ever since i bought it to turn it on after a long ie. 5hr - 6hr i have to first charge it for at least 15 mins and sometimes it wont turn on for 3hr - 4hr and then it will turn on regardless of the battery charged. If i had put it on sleep even then it wont turn on it will work as usual as it is suppose to do. I went to icare twice and they game me the device back after 1-2 weeks saying it is now not giving any issue but when i will used it next morning again same thing happened. It's like i can never go out anywhere with the laptop outside as i have to first charge it and then turn it on. Icare wont replace my device they only say if there is any issue with the hardware we will replace that hardware but i think it is useless because they don't know what the issue is. Can someone help me out what to do now ? It's been to iCare ever since i bought it now i don't want them to again do the same thing.

  • Macbook battery won't charge suddenly

    I'm having a problem with my macbook battery.
    My mac won't seem to charge for some reason. Earlier today my mac showed an "X" in the battery on the menu bar. It wouldn't charge and the magsafe didn't light any color. I thought the charger that was broken, but i did an SMC reset and then the magsafe lit up green for a while and the percentage of battery life was shown on the menu bar again. But now the magsafe is not lit up any color and the mac is not charging eventhough it it plugged in. Any idea on what to do?

    Welcome to Apple Support Communities
    OS X is telling you that the battery has to be replaced as it's damaged.
    If you have an Early 2008 or older MacBook Pro, you can buy the battery and install it yourself > http://store.apple.com/us/go/product/MA348LL/A
    If you have a Late 2008 or newer MacBook Pro, take it to an Apple Store or reseller to get it replaced. You can also replace it yourself, but you will void the warranty if it's in warranty and the cost difference is small

  • Stop battery charging with plugged MacBook Pro

    Hi,
    is it possible to stop battery charging on a MacBook (Pro) with the power plug connected? I have looked into the PM api docs but cannot find anything to do that.
    The idea is to make a menu app to toggle between "Preserve Battery Life" and "Full Power" modes. According to http://www.batteryuniversity.com/parttwo-34.htm, Li-Ion batteries loose less capacity over time when charge level is about 40% of max. capacity, escpecially with the comparatively higher temperatures that are given in a running notebook.
    So the "Preserve Battery Life" mode would charge to say 50%, then let the MB run on battery to about 30%, then charge again etc. Before taking it on the road, one would switch to "Full Power" mode to charge the battery to 100%.
    Thanks,
    Bastian

  • Nominal/Original battery charge capacity of genuine batteries for 13'' macbook (mid 2007)

    Hello everyone,
    I just wanted to ask which is the nominal battery charge of a genuine (from Apple) battery for a 13'' macbook (mid 2007). I have just bought a new one, and it has a nominal capacity of about 5500 mAh. I just would like to check if it is in good condition.
    When my old battery stopped functioning I checked some information in the web and arrived to the followings conclusions:
    Webpages:
    http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batterie s
    http://www.apple.com/batteries/notebooks.html
    Conclusions:
    - Lithium-based batteries have no memory charge effect. This means, that you don't need to be careful about charging-discharging the battery to 100% and 0% sometimes every 3 months. It also means that you can keep the battery in good health conditions not charging-discharging it at all.
    - When you are not going to use your notebook for some months it is best to keep the battery at 40-50%charge (it radically increases your battery lifetime).
    - It is also good to keep your battery at "low temperature" when not using it. It seems that 0-20ºC is ok. For example 40ºC is really bad for your battery.
    If anyone has any comment about my "conclusions", it will be useful form me .
    Thanks for the information in advance,
    Jesus

    Call Apple Customer Support 1-800-767-2775 (telephone numbers for other countries - http://support.apple.com/kb/HE57). Provide the serial number and specifications of the Mac.  They may be able to provide a replacement set of discs for a fee.  These discs will be for whatever OS was installed on the computer originally, so if you have an upgraded version you will need to obtain the discs some other way.
    You may want to just upgrade to a newer system version. Snow Leopard 10.6 would be a good one for that computer but you would need to make sure it has enough RAM to run it.  It would only cost $29 to get Snow Leopard from Apple and for the next 30-45 days until the next OS release in July it is still relatively up-to-date.
    Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..."  Copy and paste the information here, but omit the serial number and Hardware UUID (if present).
    Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575 - note by K Shaffer - http://discussions.apple.com/message/12921514 : "Some early Intel-based Macs can't use Snow Leopard 10.6 installers; of those, the Core Duo (not 2 duo) were suspect and had issues." - and a qualifier by "a brody" http://discussions.apple.com/message/13028822 : "I think that refers to the ones without at least 1 GB of RAM."

  • When the battery charged fully in macbook pro and the charger (AC Adapter)

    when the battery charged fully in macbook pro and the charger (AC Adapter) is connecting (Showing Green Lamp) to the macbook pro does that effect to the battery live of the macbook pro with Retina Display 15'' ME665
    Also I want know the Best headphone compatible with macbook pro Retina that help me to Hear and Record ?
    Notes ( the macbook pro 15" has just one port for the headphone usually it's tow for record and hear)
    Best Regards,

    The MacBook Pro charging circuit will charge the battery until it reaches 100% charge and then switch to power mode for the MBP.  When the battery drops to 93-95% charge the circuit will switch back to charging mode to top off the battery charge again.  You will not harm the battery or MBP by leaving it plugged in most of the time.
    There are many good headphone/microphone combinations on the market, best really is more a function of how much money you want to spend.  Check those offered in the Apple on-line store for features/price to see what would best fit your needs.  You can also look at audio equipment suppliers, all the earphones need is a standard 3.5 mm plug.

  • Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks.

    My Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks on the left side. I am running Lion. How do I get this to charge and turn on? Thanks

    If your model Macbook Pro is the calibrating model, let the battery calibrate. 
    If not, and are still under warrant or have Apple Care, give them a call and get a case number.  Otherwise, take the computer to an Apple store or an AASP.  Whichever is more convenient for you. 

  • New Macbook battery won't hold charge?

    I recently bought a new OEM battery from an online reseller for my Core Duo (August 2006) white MacBook. I had it for a few weeks and it worked perfectly (3+ hours of battery life, as opposed to the 7 minutes I had been getting with the original battery, don't perma-charge!), and then it just stopped. If I unplug the AC adapter, it turns off after about a second, and if I start the computer without the adapter, it turns off after about two seconds.
    I've tried resetting the SMC and reinstalling the firmware, and the computer still runs off of the old battery (albeit not for very long). I'm having the same problem in my BootCamp install of Windows 7 as well.

    I don't think the battery is your problem. Here's things to check:
    Try using another MagSafe adapter and see if that helps.
    Make sure the connectors between the MagSafe adapter & the computer is clean, as well as the connectors between the battery and the computer.
    Sounds to me like you have a problem inside the computer and that's why it won't run on battery power.

  • Keep Macbook Pro Charged or Use Battery?

    I'm confused on whether or not to keep my Macbook Pro charged or use the battery from 100% until it reaches 0% and charge it again. I've read other posts and websites and they say I should keep it charged. I know you have to calibrate it, but I'm still confused on how the battery usage works. I currently have 63 loadcycles.

    "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. "
