When I got this MBPr 13 in it could not charge. It had been lying vertically in a bag together with a rotten banana (or another fruit). Damage was heavily corrosion inside both thunderbolt ports. As there was no green/orange light and it could not charge I cleaned the banana off lightly with a toothbrush and replaced the DC-in board. Now orange light came up and computer ran fine and was charging but it started to smell like fried bananas all over my workshop. So I cleaned it in ultrasonic but after this it is dead.

I got:
- Burned thunderbolt ports (both of them)
- PPBUS_G3H 12.28V
- SMC_ADAPTER_EN 0.2V
- No S5 (3V and 5V)
- SMC_BC_ACOK 3.11V
- No green/orange light (obviously)
- CHGR_DCIN 16.48V
- CHGR_ACIN 3.96V

Did I fry the SMC while burning the banana? It was on for a couple of of minutes before I noticed the smell and then I shut it down normally.

N corrosion there. Only place was where the banana was pushing itself inside the computer aka DC-in board and thunderbolt ports. The thunderbolt ports got really damaged but the rest of the board looks new. I heating the SMC a little with some flux. No dice. Still same...
