Q: Thunderbolt display does not charge macbook pro

When connecting the MBP 2013 to the thunderbolt display through thunderbolt cable and power cord (magsafe1 plus magsafe2 adapter), the display shows, but the MBP is not charging. Regular Magsafe2 adapter works fine and charges. Checked the connectors on the adapter and it seems to fit perfectly.

 

Any suggestions?

MacBook Pro with Retina display, OS X Mavericks (10.9), less than 1 week old

    Same here; a new MagSafe adaptor resolved the issue.

    And another confirmation from Amsterdam:

     

    - MBP didn't charge anymore with TB

    - sometimes it did, but why? I don't know.  I never could reproduce it, so no logically explination

     

    Bought a new magsafe adapter. And yes, all is working again. Never thought it could become defective.


    Which makes me wonder : do I have warranty on such a simple device?

    I think the answer is: "yes you should"

     

    Apple simply supplied a batch of faulty adaptors which should be exchanged under warranty. (This can happen with any HW vendor, nothing to be ashamed of.) However given Apple's deafening silence in this conversation I don't get the impression they intent to do so.

     

    For many people it's probably just not worth the effort....

    I don't think Apple look at the forums

    IMO that would not only be silly but also a missed opportunity to get firsthand product feedback and manage customer sentiment.

    The Magsafe 2 adapter is not covered under warranty.  It will be considered a DIY repair and you will be charged $19.13 for the new adapter and shipping.

     

    I know this first hand.

    Yes. It's under your own warranty. Walk into store. Buy one. Leave store. Take it out of package. Put defective one in package and then tell them it doesn't work and return it. LOL.

    That's IF you have an Apple store, which I do not.  I contacted Apple because I would never have thought that this wouldn't be covered under warranty.  I had just bought my display 6 months ago.

     

    I should have just gone to Best Buy and bought one for $10 and been done with it.  I'm still waiting for the credit adjustment from Apple on the $19.13 because no one told me this would be billed to me so I raised a stink.

    They probably cost a $0.25 to make. Apple should just hand them out free.

    At least in Australia they would be covered by an implicit warranty.

    I had the same issue today with Thunderbolt display and last generation MBP 17". It was not charging. I have a few peripherals connected and was running two virtual machines. As soon as I disconnected a dual USB connected peripheral that was pulling a bit of power the MacBook started charging. So maybe having too much power draw overall through the various components may just disable the charging. I also checked with the units original power supply and it was acting the same as the thunderbolt display.

     

    This is all without any magsafe adapters in the chain.

    One more piece of data: plugging the same high power draw USB peripheral into the thunderbold connectors/hub rather than the MBP (so pulling power directly from the display instead of through the MBP) also fixed the issue.

     

    So try moving high power draw components to the thunderbolt display directly.

    Ok one last update: it all seems to be thermal. I was monitoring the temperature and based on overall power draw, processor load, etc, the temperature was high, and this disabled the charging. Which was suggested earlier here...
