Hey,
About 3/4 months ago my macbook air early 2015 i7 stopped charging. The light on the charging cable flashes green for a second when i put it in and then after that with very slow intervals flashes amber. On the macbook it said that the battery was not getting charged.
I then bought a new cable and it started charging. So now, 3/4 months later i have the exact same thing with the new charger.
Some background info: i had replaced the battery in 2021
