Asus K54LY rev 2.1 - no post

Hello
I have this laptop, which came with dc jack broken, and after repair it didn't post anything.
So there it goes - searched schematic and power seq. Untill now what I discovered is PIN 29 from ITE8572E that hasn't any signal or voltage. Rest of them are ok, 3.3v, attached a photo for better understanding.
Do you think is ITE damaged ? Or ME region has problems ?
Tried 2 cpu's, memory, bioses, all voltages are present on the board.
Any ideas ?
