Hi.

I have an A2681 820-02536 with 20V on ampmeter, but when it reaches 0,5A powers off.

I can see the Apple logo, but then it powers off imediatly (+-1 second after logo appears).

On thermal cam, I can see U/L8100 getting hot more or less at the same time the mac powers off. Not sure if it is related...

I've removed L8100 and got 0.058 on PPVDD_AWAKE_PCPU, and 0.500 on BUCK0_LX0

Can you help?
