So, I've been having an issue on and off for a year or two where my macbook airs magsafe charger wouldn't actually charge my device, and I'd have to reset the SMC 10+ times to get it to recognize my charger.
I've recently gotten access to a second macbook (pro) so I was curious if that charger would work for my macbook air. Lo and behold, it works immediately after plugging it in the first time. So, the other macbook charger works for both that macbook and mine. My charger works for the other macbook, but in mine it takes a bunch of resetting to get it to work.
What could be causing this weirdness?
Not sure if it would help, but here's a pic of my magsafe port (there is no removable debris, it just appears to be discolored and scratched a bit):
