A1932 820-01521-A no power

Hi.

I have an A1932 820-01521-A no power with no power.

I have 19V on ampmetter, and reach 1.5A with battery conneted.

With board alone on the bench, only 0A.

On IR cam, only T2 gets hot. Can I replace it?

What other voltages did you check on the board?

Sorry, my bad. I've just assumed T2 was shorted.

My boardview and schematics are not correct. Do you have any to share?

PPBUS_G3H = 12.56V
PP5vG3S = 5.1V
PP3v3_G3S = 3.3V
PP1v8_G3S = 1.8V
PP3v_G3H = 3.0V
PP1V8_SLPS2R =1.8V
PP1V1_SLPS2R = 1.0V
PP0V8_SLPS2R = 0.79V

PP1V2_AWAKE = 1.1V
PP1V8_AWAKE =1.8V
PP3V3_AWAKE = 1.8V

What about Intel side?

Check diode mode on all big coils and SSD power rails.
