i have a macbook air A1465 EMC 2631, when i plug in the charger, it doesn’t light up and macbook air doesn’t turn on, what is the problem?

There are several possible reasons why your MacBook Air A1465 (mid-2013) with EMC 2631 isn’t turning on and the charger indicator light isn’t illuminating. Here are some troubleshooting steps you can try:

1. Check the Power Source:

  • Verify the Connection: Ensure the MagSafe connector (power cable) is firmly plugged into both the MacBook Air and the power outlet. Sometimes a loose connection can prevent charging and powering on.
  • Try a Different Outlet: Plug the charger into a different outlet to rule out a faulty wall socket.
  • Inspect the MagSafe Connector: Look for any physical damage to the MagSafe connector itself, such as fraying wires or a loose tip. A damaged connector might need replacement.

2. Reset the SMC (System Management Controller):

The SMC manages power functions on your Mac. Resetting it can sometimes resolve power-related issues. Here’s how to reset the SMC on your MacBook Air:

  1. Shut down your MacBook Air completely. Ensure it’s not sleeping or hibernating.
  2. Connect the MagSafe charger to your MacBook Air.
  3. Hold down the Shift + Option + Control keys on the left side of the keyboard.
  4. While holding those keys, also press and hold the power button for 10 seconds.
  5. Let go of all the keys at the same time.
  6. Try powering on your MacBook Air normally.

3. Check for Battery Issues:

  • Observe the MagSafe Connector LED: While the MagSafe adapter is plugged in, a green light usually indicates a healthy charge, an orange light signifies charging, and no light typically means no power connection.
    • If there’s no light at all, even after checking the connection, it could be a faulty MagSafe adapter or an issue with the MacBook Air’s charging port.
  • Try a Different MagSafe Charger: If possible, borrow a known-working MagSafe adapter to see if your current one might be faulty.

4. Additional Considerations:

  • Listen for Fan Noise: If you plug in the charger and hear the fan running briefly, it might indicate the battery has some power and the logic board (the main circuit board) might be functioning to some extent.
  • Try booting into Safe Mode: Booting into Safe Mode performs a basic startup using only essential software. If your MacBook Air starts up in Safe Mode, it could indicate a software issue causing the normal boot process to fail. Instructions on entering Safe Mode can be found on Apple’s Support website for your specific macOS version.

If none of these solutions work, your MacBook Air might require further inspection by a qualified technician. Here are some possibilities:

  • Faulty MagSafe Charger: A malfunctioning MagSafe adapter might not be delivering power to your MacBook Air.
  • Logic Board Issue: Problems with the logic board, the core component of your Mac, could prevent it from turning on.
  • Battery Failure: A completely dead or faulty battery might prevent the MacBook Air from functioning even when plugged in.
