Q: Macsafe charger won't charge

The MacSafe charger works for a few seconds, then  the lights go out. Sometimes it fully charges, now I have to keep unplugging it and plugging it in again and it charges each time for a few seconds.  Help !

MacBook Pro

    Very Good of you to reply with hep. I sincerely appreciate this and will keep this 'on file'.  Presently the charger IS working without me having to reset it... hmmm. Crazy.  Thank you. xx

    been having similar problems (using a MagSafe to MagSafe 2 adapter). I tried cleaning around the ports and a SMC reset. Didn't really help. Occasionally, when it is working, the connector and that corner of the laptop get very hot.

     

    I noticed that if I flip the MagSafe adapter 180, the charging works every time and the laptop / connector do not get hot. I am starting to suspect the adapter.

    The connection on the magsafe charger wire that connects to the MBP has spring loaded pins.  Make certain that they are moving freely.

    Holy cow -- this actually WORKED for me!! Thanks so much!  I hadn't used my MBP in a few months, and when I turned it on, the battery WOULD NOT CHARGE.  The green LED light was on on the mag safe power adapter, my battery status was NORMAL -- but it would not charge the MBP.  I just did the SMC reset -- and VOILA!  The mag safe adapter light turned amber, and is now charging!  Thank you again!!
