A1278 - 2351: No start

Hello,
I have a MacBook Pro 13.3 "early 2010, A1278, EMC 2351, SN WQ031BPZATM, 820-2879.
He does not want to light up anymore because of the water spilled on the keyboard.
Green LED of the charger that turns on, but nothing, black screen, no noise, no fan.
No visual damage on the motherboard.
Nothing that heats up abnormally.
I suspect Q7030 and Q7035 but not sure, how to test them?
Cordially.

Disconnect keyboard and use R5014/15 pads, instead of power button.
Post exact PPBUS_G3H voltage; keep battery removed.
Also check L7750 voltage and RTC signals.
 
I have 0 ohm.
The tracks are OK, I send pictures of U7000.
