Pufff, you've injected 12.5V on pin18 of U8900 and to U5310 too (pin 3).
U5310 should be fried now, as is powered from 3.3V only.
Change both chips.
You have luck if SMC is still Ok.

Might want to change C8913 too out of caution, it's only 6V3 rated, seeing 12V+ might have upset it.

U5310 doesn't appear as NO STUFF on schematic.
The surrounded components not solder too, or U5310 was ripped off?
It is the GPU current sensor; a good reason for SMC sensor error...
