Battery problema rMBP late 2013

Hello to everyone,

I have a strange problem with my 2013 retina macbook pro. The battery status is normal but the power supply does not charge the battery. The computer powers on without any button pressure when I plug in the power and goes down (immediately) when I remove the power. It does not work without power supply. I tried a reset of SMC and clean reinstall of High Sierra but nothing changed. This problem started a week ago and the battery level was 100%, now it is 13% and very slowly discharging. It seems that the battery behaves as it should do when the computer is in stop mode. Moreover, I noticed that in System Report/Power the value battery Amperage (mA) is 0 even if the voltage is not 0.

Hope I gave enough details to understand the problem. Does anyone have any suggestion? There is the possibility that the battery is in a kind of protection mode and changing the power adapter could solve the problem?

The computer works very well since Nov/Dec 2013 and has around 630 battery cycles, it is out of guarantee here in Italy (2 years).

Thank you very much

Giuseppe
