U5110 For macbook air (SMC_RESET_L) Damage
Note:
SMC_RESET_L should be 3.42v. 0.5v means shorted SMC, 0v means bad U5110 usually.
1) What does R5100 measure? This resistor pulls up SMC_RESET_L to 3.42v.
2) What voltage do you get for SMC_RESET_L when you remove U5110?
If you remove U5110, R5100 is good, and SMC_RESET_L is still low - the SMC is pulling it down.
If you remove U5110 and SMC_RESET_L goes up to 3.42v, then U5110 was bad.
