The April 2014 update of Apple's 13" MacBook Air features refreshed dual-core i5 and i7 processors, plus slightly increased battery performance.

No light on charger, no battery available, powers on

Hello,

I am working on a 2014 MacBook Air and I have a situation where:

  • No lights are coming on charger
  • Hold power, starts up, chimes, shows apple logo and powers off
  • Disconnect battery, hold power button, fan comes on full speed and laptop boots up.
  • Re-connect battery while on, indicates 'no battery available'.
  • Reset SMC, no change.

I am thinking the I/O board is bad and/or battery but shouldn't the light on the charger come on regardless of the battery status? Any help here would be appreciated.

Hi

How does the logic-board look

Keep an eye out for any corrosion/damage and also have you tried a new battery?

Thanks:-)

I was looking for corrosion but couldn't find anything. I am going to try a new battery to see if that resolves the issue. Thank you!

I replaced the I/O board today and this resolved the issue. Thank you!

That would have been my second guess. Glad it was something relatively easy to sort out!

This could very well be a battery issue. It’s unusual that there’s no light on the charger, but the first thing I would try is a new battery. Fans coming on at max speed is normal when the battery is disconnected due to lack of communication from battery sensors to the SMC.
