MacBook Air power on problem

[lord]

The laptop is dead. Has 3 and 5 V, but that is as much as i can do. I can't recognize the keyboard controller, and i don't have the schematic.
It is a dead end for me.
Any help would be appreciated.

Motherboard model is 820-2179-C, notebook model is A1237.

I have three motherboards, none works, i would be happy if i can manage to power up at least one of them.

i have schematic and board view files but can send them 2 days later(i'm out of the city), if you have a known good keyboard, try connecting it. power switch is on the keyboard and most of the cant power issues wit this model is about keyb.
good luck

OK.
Tnx!

We will wait for your bord view.

I have a known good keyboard, so i ruled that out. It must be the board it self.
