Only charging intermittently - have tried everything - please help
So I my macbook charging port burned up after years of use. I bought a new port, connected it, then bought a new charger (used, but in 100% condition, and is official apple charger). It was working fine for a few hours, charging great, then suddenly stopped charging when I reconnected it. I thought the spare part might be cheap/busted, so bought a new one, having the same issue.
It charges only sometimes when I connect it (lights up green, then orange). Mac charges perfectly, its just when I disconnect then reconnect it stops.
What could be causing this issue? Logic board? Its very frustrating because as far as I can tell there is nothing wrong with it.
Have tried all the various PRAM and SMC resets, to no avail. Also checked battery health which is fine I believe.
Please help me.
Is this a good question?
