Hi guys!
I have this MBA 1,6 A1237 which is dead at the moment and i need some help on a component level.
When i press the power-button nothing obviously happens, though the button is functioning and the Logicboard get the signal, I can say that cause i am able to reset the smc by shift+ctrl+alt+cmd and power.
The only way i get the machine to power up is by short circuiting (see picture here)the 4th and the 2nd jumpers on the topcase when the IPD Board Flex Cable is connected, the machine starts, i get POST and all but when i release those jumpers it shutdown immediately.
I just wonder if anyone here have experienced that and found a fix.
I do have other boards laying here that i can pull out components from.
Btw..I did disconnected all attached cables that might be short circuiting and it seems to be on board, a component issue but which one?? how can I find out of it?

Thanks in advanced!
