#1 APPLE MACBOOK AIR 2011, A1370, EMC2393, 820-2796-A, Missing S0 State (5V and 3.3V)

Hello Everyone,
I have MacBook Air with green light on charger but when I press power button fan spins for short time and stops. Laptop does not start.
After removing motherboard and plugging charger in I get green light but fan does not spin.
Power draw is only 26mA. Both (5V and 3.3V) for state 0 are missing.
PP5V_S0 (0.04V and line resistance is 42kΩ)
PP3V3_S0 (0.02V and line resistance is 8kΩ)
Are both voltages created by single IC ?
Thanking you in advance.
Regards,
Rafal S.
