Magnetic part of charger (macbook pro)

I bought this computer about 3 years ago. Today I come to unplug my macbook and the gray part that is magnetizes got stuck in the computer. I am left with the cord that has 5 little golden rods coming out at the end of it. I tried putting it back together and hopping that it would come out but the gray part is still stuck there.
So, I guess I have to buy a new charger but how can I get the gray part out of the socket??? 
thank's

Easy, its just a ceramic neodymium magnet, grab some needle nosed pliers and gently pull it out.
WITH THE POWER OFF.
You can easily reattach it to the charger end with binary (2 part) 2-ton epoxy,...it takes 24 hours to cure, even the "1 hour" epoxy binary still should not be used for at least 7 hours.
Its possible Apple could give you a replacement charger without charging you, but I doubt it given the age. Take it in and find out
IF you glue it yourself, do NOT use superglue, ...it wont last in affixing the ceramic neodymium to the charger end.   Use binary epoxy you can find anywhere.
If the neodymium isnt broken, I wouldnt buy a new charger for $80, just epoxy it and let it cure for 24 hours.  But thats your choice

    Here is apple's instructions in calibrating the battery KB Article
    As for leaving it plugged in, that's the normal process most people do, there is circuitry in the computer to ensure the battery does not get over charged. Aside from calibrating it, I'd avoid any deep cycles, that is draining it completely, you're better off plugging it in when you have the opportunity and not wait until the battery is nearly drained. Deep cycles can shorten the life span of the battery.

  • I got my magsafe 2 60w is it safe to charge macbook pro retina 15 pouces

    I get my magsafe 2 60w is it safe to charge macbook pro retina  15 pouces

    It's not a good idea to use a lower wattage power supply than what the machine shipped with. The 15" comes with an 85 watt adapter and that's what you should be using. You can go in the other direction with no problem, like using an 85 watt on a machine that came with a 60. If I were you, I go get the correct charger.

  • Only part of my macbook pro keyboard backlight works

    only part of my macbook pro keyboard backlight works , all settings and f6/7 keys work ok but only a triangle in the centre lights up, so the rest of the keyboard is dark.
    Pleqase someone shed some light.
    Bought in May 2012

    It is likely a hardware defect.  If you bought it in May of 2012, it is still under warranty.  Take it back to the store or mail it in to be fixed.

  • Parts unavailable for macbook pro

    Just spoke with apple senior advisor and was told that after five years parts are unavalible for my computer. I never thought I would say this but this may keep me from ever purchasing another apple product. My battery is bad and he said I cannot get one. period. for a 2000.00 investment this really *****. 

    An Apple senior advisor.. what is that? Did you contact a Genius at an Apple Store? Perhaps their is a misunderstanding.. could he have said something like "Apple would charge alot of money for these parts and you can get it cheaper by going to an aftemarket company." 
    Here's a link for the older MBP battery for $129..
    http://store.apple.com/us/product/MA348LL/A/rechargeable-battery-15-inch-macbook -pro?fnode=5a
    Failing that go to OWC at macsales.com and surf their website for upgrade products.. like a HD or memory.
    I just a new baterry from them for my Early 2008 MBP for $79.

  • Battery issue LoadCycle count increases without charging , MacBook Pro Retina 2012?

    Hi
    i have the feeling that i have a battery issue.
    It looks like that  the battery cells are in one region defekt.
    Once i cross about 30% last charge it starts draining very fast within 10-15 Minutes the MacBook switches off.
    In order to proove this i have written a small script in order monitor the battery and some other counters.
    And here is realized anothe interesting topic.
    The Load Cycle Count can increase even if you dont charge !!
    Below you see that the LoadCycle Count increased from 373 to 374 even if i didnt charge.
    Any ideas on that. Or does anyone have the same issue ?

    tesme33,
    have you tried resetting your MacBook Pro’s System Management Controller, to see if that affects its energy consumption?
    When I run
    ioreg -n AppleSmartBattery -r | grep -i CycleCount
    on my MacBook Pro, I get two different output lines. You might want to adjust that part of the CYCLECOUNT assignment to have
    ioreg -n AppleSmartBattery -r | grep '"CycleCount"'
    instead, to ensure that that returns only the intended single line.

  • The thunderbolt display does not charge macbook pro,

    there is a magnetic adapter for the power cord...do I need to find a new cord for the display or is there a problem with the mac book pro?

    The Thunderbolt Display has two cables to connect to the MacBook Pro. 
    The first is the Thunderbolt cable, identified by the lightening bolt on the connection.  This carries data to the display for either passing through to other devices connected to the display (in this way, the display unit also acts as a hub for other devices (USB, Thunderbolt or maybe FireWire), or to the display unit to put on the screen.  This cable does NOT charge the MacBook
    The second is the power cable.  The current version of the display (as of April 2013) contains the power cable to connect to the older type of MagSafe connections on the MacBook, and an adaptor to connect to the newer MacBook's (MacBook Air and MacBook Pro Retina).  You have to (of course) use the the adaptor or not depending on how old the MacBook is.  It is an akward thing, but you have to use the adaptor for the newer Macs and not for the older Macs (sounds backwards, but that is the way it is).
    The older versions of the display (mid 2012) do not come with the adaptor and you have to buy one if you have a newer Mac.  Or you can continue to use the power brick that came with the Mac.
    Soon, (hopefully - but not soon enough IMHO) Apple will release a new version of the display which will (in addition to being thinner, lighter, use less power, etc.) will contain a power cord that will fit right into the newer Macs and you will need an adaptor if you have an older Mac.
    Sounds kind of confusing, but if the power cable from the Thunderbolt does not fit your Mac, you have to use an adaptor.

  • What is the best way to charge MacBook Pro?

    What is the best way to recharge the batter on a MacBook Pro? i was wondering if i can keep the battery charging overnight, or if i should drain it before charging it.

    Plug in the AC adaptor, connect the cable to the MagSafe connector on the computer.

  • Part content of macbook pro

    I want to know what the US part content is of a MacBook Pro.
    Specifically, I want to know where each part is made and where it is assembled. If nothing else, I want to know what parts are made in the USA.
    Thanks in advance!

    Consumer Reports keeps track of the US content of automobiles; they may have something on computers. Worth contacting them.
    I am not aware of any name-brand laptops made in USA. There may be some "assembled" here but I am willing to bet all the components come from offshore. If you want 100 percent American content in a portable computer, you may need to build an abacus!
    As an aside, the last Consumer Reports listing of the US content of cars--parts and labor--the high score was 91 percent. Wanna guess what vehicle? A Toyota Sienna mini-van! Made in Kentucky! Some of those big GMC trucks tough guys like to drive had zero US content.

  • Battery time remaining (how to properly charge macbook pro retina)

    I'm a new macbook user, using a macbook pro 15 inch. I've been plugging in my charger when the battery gets down to around 20% and unplugging it when the light turns green (at 100%). I thought macbooks had a battery life of around 7-8 hours, but at fully charged, my time remaining (when I click on the battery icon the top right) says 5 hours. Can a  more experienced user correct me on as to what I am doing wrong in charging my macbook?

    Two points:  The 'Time' setting is one of the most unreliable pieces of information on your MBP.  I set mine to '%'.  What it tries to show is based on what the MBP is doing at that very instant.  If you open Activity Monitor, you will see that the internal processing is very volatile.
    What Apple advertises as time on a full charge is based on ultra conservative settings and use.  It doe not reflect the 'real' world.  Read the fine print and note the words 'up to', nor will, guaranty or promise.
    Your battery run time will be a reflection of what applications you have open and the respective resources these applications require.
    Here is a link to some good information regarding your MBP battery and its usage.  This will give you something to do for the rest of the afternoon.

  • Tingling Sensation when charging Macbook Pro 13 inch 2015 with Force Touch

    Today, I just got my Macbook Pro 13 inch 2015 with Force Touch.
    When I charge it, there is a VERY STRONG tingling sensation. Almost feel like a strong vibration. I believe this is what they call a "mild electric shock". After testing the new machine with different power outlets (both at my house and other people houses), with same result .... my fingers feel all numb.
    I am going to Apple service next week with this.
    Anyone experiencing the same thing?

    Usually that indicates a bad ground in the source system.  Perhaps a licensed electrician should be employed to check out the wiring.
    Ciao.

  • Problems with charging MacBook Pro with Retina display (15inch)

    Today, I connected my MacBook Pro with Retina display 15inches to my charger and it did not charge but was showing that charger is plugged but battery is not charging. I checked by disconnecting my charger and I had only 2% of charge left. By the way, when I disconnect my charger, laptop works on its battery.

  • When best to charge MacBook Pro?

    Hi, I'm a Mac newbie. Got my first MacBook Pro (2012 release). When is it best to plug the ac power adapter - at what battery percentage or battery time remaining - to maximize the battery life? My practice has been to plug it when there is only about 5-10 minutes remaining on the battery. Is that okay?

    You can leave your Macbook plugged in most of the time - Apple suggest you keep it plugged in when you're close to a power outlet....
    Once in a while, use it under it's own power and once it's down to 75%, charge it back up to keep the battery in optimal condition...
    Never let your macbook battery get to 0%, it will do more harm than good to your battery....
    Optional - once a month, use your macbook under it's own power and when it's down to 25%, charge it back up...
    Good luck

  • Without any charger,Macbook Pro is slow

    My 13 Macbook Pro became slow during a power cut in the electricity.
    The speed goes back to normal only after I plug it to charge.
    I have tried:
    >Canceling "Put Hardrive to sleep when possible" in Energy Saver
    >Checking Activity Monitor;Nothing is slowing down the speed
    >Shutting down,holding (left shift,control,option,and power button)for 10 seconds and then starting the laptop again
    >My Adobe Flash is up to date if it is revellent
    Right now,It's still plugged to the wall.
