Power Issues After Spark.

Hi, I am having some issues with the battery and charging on my MacBook Pro. Recently I noticed a spark from the MagSafe port when I connected the charger. Not long after the battery low warning started flashing repeatedly in a way it has never done before. It was as if the charger was being connected and disconnected repeatedly.

I thought the battery was at fault so purchased a OEM replacement but this has not fixed my issue.

My MacBook works perfectly normally except from the fact I can no longer charge the battery. The battery status says Battery Not Charging and Power Source: Power Adapter but the power adapter is not connected and it has no affect when it is. When I do connect I get a very dim green light.

I have tried the SMC reset and NVRAM/PRAM reset but again it has not helped. I am starting to think that perhaps the charging port was damaged and a replacement would solve my issues.

Any help would be appreciated.

thanks

Is an original charger being used or is it an aftermarket one? Also try cleaning the charging port because there is probably some lint / metal foreign pieces stuck to the magnetic part of the MagSafe charger.

Thanks Ben, yes it is a brand new Apple charger. I have also cleaned any debris from the port but again it still won’t charge. What’s confusing is the macbook thinks it is running on the power adaptor when it is not plugged in and is in fact on the battery.

Thanks

Thats a sign of the charging logic on the logic board is damaged. It could be a damaged one-wire comm line from the DC In Board to your SMC.

@danj Does this mean that the whole logic board would need replaced or can it be repaired?

Without deeper inspection and testing its hard to say.
