Hi, This is liquied damaged and some one has cleaned before. There is no visible corrosion or damaged as I cheked with microscope. board is pretty clean. cheked only with dc in board and fan same out come.
All the power rails present accurately then after 20 sec missing pm_slp_s4. ppvcc_s0 12.1 ohms resistance to ground. smc reset works. doesnt respond to pram reset when it boots. takes 12 secnds to get the chime . u7100/u6100 pretty clean and voltages are accurate. greatly appriciate your help.
