Greetings,

My MacBook battery is not charging. What could cause this?
A1342

- MacBook works with battery until drained.

- Light on magsafe plug is dim or not lighting.

- Power adapter is new.

- Battery is new.

- Magsafe board is new.

- I reset the SMC.

Can someone with knowledge of the logic board components tell me which could cause this?

It's not necessarily an issue with the logic board. Even though they're new, you could have a faulty battery or charger. Have you tried other chargers? (if you have access to other MagSafe adapters). You can also take it to Apple. They can diagnose the problem quickly.

This should answer most, if not all, of your battery questions:
