Macbook Pro Charging Problem - Charges Erratically.

My Macbook Pro is charging erratically over the last 3 weeks. It charges at certain positions,while it does not charge at other positions. I tried resetting the power chip but it didn't help. I went to genius bar, apple and got it checked. However, they said that there was no problem with the adapter. Any suggestions?

It sounds as though you may have a frayed DC cable leading from the adapter brick to the computer. These cables sometimes fray near the brick or the MagSafe plug due to excessive bending in those locations, and the conductors inside them can break and make only intermittent contact when that happens. In the right position, contacts will be made and maintained and testing will show nothing wrong, but shift the cable slightly, the contact may fail, and charging may stop. When movement of the machine or the cable causes a change in charging behavior or power delivery, a frayed cable is the first suspect.

  • Macbook Pro (Early 2011) charging problems

    Hey Guys,
    The Macbook Pro was bought in July of 2011 which is only a few months old .When I plug in my magsafe to charge the macbook pro it turns green, then orage to show that it is charging. However, after a few mintues of charging the orange LED light goes off and it stops charging, then the orange light comes on to charge for another few mintues then stops charging. I have been aren't to charge the macbook pro
    Is the charger broken? I cant find or see anything tearing in the charging cable or anything broken with the power brick.
    Thanks

    First try resetting the SMC...
    Reset SMC of a MacBook or MacBook Pro’s with an internal battery:
    * Shutdown your MacBook/Pro
    * Connect the power adapter to your Mac
    * On the MacBook/Pro’s keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
    * Release all keys and the power button at the same time
    * Boot your Mac as usual
    Then try resetting the PRAM...
    Resetting the PRAM
    You reset the PRAM by rebooting a Mac and then immediately hold down theCommand+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won’t work.
    If those two tricks fail, take the adapter and the laptop to the applestore. IMO it sounds like a battery issue and not a charger problem.

  • My macbook pro will not charge when I am using it.

    My macbook pro will not charge when I am using it. My battery will say "charged" then "not charging" and it goes back and fourth. It says "Power Source: Power Adapter". But when I use my pro it will loose the power source then reconnect a second later to it. This problem is getting annoying because I have to stop using my macbook pro to charge it.

    Reset SMC.

    If this does not help, contact Apple.

  • My macbook pro won't charge due to an electric shock

    My macbook pro won't charge due to an electric shock that was caused from a charger that was in a bad condition, the computer didn't turn off when it happened but it stopped charging. When the battery died it refused to charge with any charger, I even bought 2 new ones. I sent it to apple and they are asking $650 for fixing it! The problem is that the macbook is only a year and a half old and I live abroad where there is no apple branches or any of that. I had to send it to the USA first. Also, I might lose everything saved on the macbook after fixing it! Any solutions? please help!

  • My macbook pro is not charging ? Why

    MY macbook pro is not charging. the battery percentage sign disappear or shows there is no battery power. I take it to Apple shop and they told me after checking the problem is of the Hard disk . I have many important things on it . What do you think ?

    Perform a SMC reset:

    After you have backed up your data, open System Profiler>Power and post the following from your MBP:

  • MacBook Pro '11 "Stops Charging" as soon as iMovie Exports Video.

    MacBook Pro '11 stops charging as soon as you start exporting video from iMovie. A video demonstration in the link explains the phenomena.
    http://www.youtube.com/watch?v=rnpB5G2pgMI

    Respectfully, I disagree with your claim that nothing is wrong.
    While I understand the behavior is by design, most users - myself included, believe that when the laptop is plugged in, it's charging and can operate indefinitely as long as it's plugged in. Instead, a Macbook will, in certain circumstances, shut down completely if under heavy load for too long. Heavy load isn't just rendering complex 3D designs or transcoding HD video - things many users will never do - but it does include activities as seemingly trivial as playing videogames or watching Netflix where playing for too long when the battery is significantly less than full exposes the user to a very possible shut down.
    Just this evening, my MacBook Pro (2011) nearly died while transcoding video in Final Cut Pro - while it was plugged in. This is a real problem for a pro user on the road. Simply being plugged in is not enough when historically it has been.
    Again, I understand that the MacBooks exhibit this behavior by design, but it is a design that is counter to most people's experience of electronics.
    Rather than have this simply be "the way it's designed," how about Apple consider providing an option that reduces the maximum system load to a lower threshold that will allow for effectively indefinite runtimes (keeping in mind engineering concerns like heat dissipation)? I'd be willing to deal with lower clock speeds (and the resulting lengthier processing times) in certain scenarios of my choosing if it means my project won't be exposed to an unwanted shut down like it nearly did tonight. This is feedback I intend to submit to Apple after tonight's episode.
    While I'm no longer concerned that something's wrong with my MacBook Pro, I don't believe the current "normal" behavior is good enough for a $2,000+ laptop for professionals.

  • My Macbook Pro will not charge. I have tried other charges and nothing. Can the MagSafe port go bad? Is that expensive to repair?

    My Macbook Pro will not charge. I have tried other charges and nothing. Can the MagSafe port go bad? Is that expensive to repair?

    The port can fail. Internal boards can fail. Batteries can fail. All with the result that no charging occurs. 
    You can try Resetting the System Management Controller and you can try Troubleshooting MagSafe adapters. 
    But usually you will have to take the mac in to a service place for testing.  It can get expensive, although occasionally it is not.

    Hi sdennisonta,
    If you are having an issue with charging your MacBook Pro, I would suggest that you troubleshoot using the steps in this article - 
    Mac notebooks: All about batteries - Apple Support
    If the battery appears to be working correctly you may want to see if the issue lies with your power adapter. Use the steps in this article -

    Some basics please, what vintage is your MBP, have you plugged anything else into the wall socket to verify that it is live? which light doesn't turn on, the charger or the MBP?
    Hold the power button down for 15 seconds, wait for 2 then press it normally and see te MBP it turns on

  • 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.
