So I picked up this 2012 MacBook Pro,Upon plugging it in I hear a click every 1/2 second, And the light on the MagSafe charger is going crazy from green to orange within milliseconds over and over,I assume this is a MagSafe Board Issue? @danj - What do you think? Update 9/2/2022:
@beanman56 unfortunately im not @danj but is it doing this on multiple chargers and is the charger all they way in the wall iv see this happen if the charger isn’t in the wall properly:-)
