Have a board in thats been dry-cleaned (see my post in the business forum), but there's no visible damage to the board: looks absolutely clean.
Have all normal readings on rails below PP3V3_S4, but PP3v3_S4 is missing (0V). Cannot find any trace of corrosion anywhere.
Has a green and then orange light on the magsafeboard, but doesnt power on (i know that the fan spins only at higher cpu-temps)
Have tested with knowngood battery.
PP5V_S5 = 4.97V
measured P5VS4_EN on pin 2 of U8060, but get 0V
I don't fully understand how PP3V3_S4 is created.
any pointers?
