MacBook Air wont turn on unless plugged to charger

So im having this issue with my MacBook Air early 2014.

It won´t turn on unless plugged in to the charger and after booting up, i can unplug the charger and it will work fine.

  • already reset SMC
  • Restore OS via USB
  • Tried new battery

Issue persists.

Any help will be thanked!

That points to a logic board issue at charging/main power circuit. Usually that comes from a liquid damaged Mac or a poor quality aftermarket charger. One way or the other it would need component level repair or a logic board replacement.

obviously i need a component repair, thats why im asking where to start looking. No water damage neither cheap aftermarket charger used...

Both batteries are OEM, replacement was pulled from another MacBook


If there are not obvious related causes you may try with a I/O board and relevant flat cable replacement to start with. If that doesn't help you'd need to start probing U7100 and relevant circuitry, then SMC.
