    I am having a weird problem where my MBP won't charge reliably.

    I will plug in the magnetic part to the computer and it will charge for about 10-20 seconds and then it will stop charging. I can then take it out and plug it back in and it might work for a few minutes and then stop or it might not work.

    There then was a period of 2 days where the charger wouldn't work at all, so
    I bought a new 60w power adapter hoping that this was the problem but the problem is still there. I did an SMC reset and it didn't appear to help. Surprisingly, the old charger that didn't work at all is now working but it also has the same 10-20 second problem.

    What do you think the problem is?

    is there any gunk inside the power port on the MBP?

    I looked but it doesn't seem to be dirty. What is the protocol for cleaning it properly. I can try this

    Most probably your power socket (from the wall) is providing less power than it should. Happened to me earlier this days. I was getting a message "Battery Is Not Charging" while appeared "Power Source: Power Adapter".

    Solution: try other sockets, other houses. To me, using another power socket or getting rid of any external power stabilizers solved the issue.

    Q-tip and isopropyl alcohol. Make sure the computer is powered off and remove the battery if possible.

    I would also suggest running Coconut Battery to see the health of your battery. It could be as simple of a problem as the battery being bad, a MagSafe board issue (a relatively inexpensive fix), or as serious as a Logic Board problem.
