820-00165 - Battery problem

[Eleways]

Hi

I've a problem on a MacBook Air 13" 2014, motherboard 820-00165-a.

It works fine but don't detect the battery.
It works with battery without power supply plugged but the system don't detect battery (the battery icon had a X inside). If I connect power the magsafe led start green and become amber. the battery will charge and work.

We try to replace ISL and check resistor around, without success.

Any suggestion?

Thanks and best regards

Luke
