A1534 820-00244 no power

[hgoncalves]

Hi,

I have an A1534 820-00244 with no power.

I have 20V on ampmeter, but 0A.

No big coil seams to be shorted.

PP3V3_G3H = 3.289V

PP5V_S5 = 5V
PP5V_S0 = 0V

PP3V3R3V0_AON = 3.298V

PP3V3_S5 = 0V and 0.388 on diode reading.
PP3V3_SUS = 0V and 0.398 on diode reading

Can you help?

What is exact PPBUS_G3H voltage, w/ and w/o battery connected?

Did you test in SMC bypass mode?

PPBUS_G3H has 8.69V with, and without battery connected.

SMC bypass has the same result (no power on)
