SMC_PM_G2_EN switching on and off every 0.5 sek or so. Clock chip is ok getting the 32Khz and the 25Mhz. What should I look for more ? No signs if water damage on the board. Anyone had this problem before?
On another note had the same problem on an air 820-3437 replaced U7501(U7200 equivalent on 3115 ect.) and it worked so not always the SMC. So its easy to desolder the U7501 and see if the SMC_PM_G2_EN signal becomes stable.
same thing as what i said, u7200 on an a1278 is u7501 on a newer a1466. it can pull down the signal from the smc. i always try the latter before the smc because it is easier to put back on
