Macbook air 2018-2019

Putting voltage tester on
switches from 5-20v
0.00 amps

Cannot seem to find any shorts

when plugging in cpu gets warm but not overally

when using thermal camera nothing really pops out

Any history available?

Is the machine recognized into DFU?
What about PPBUS_G3H and 3V3_G3H_RTC?
T2 gets its SLPS2R and AWAKE voltages?

Well customer states just doesnt turn on anymore
ppbus_g3h no short- voltage 12.2

 

[ohspecial1]

I will put it back together and connect it to an imac see if its DFU mode but would think no amps is odd

 

[ohspecial1]

I know these a prone to cpu failure or short to cpu any direct checks
