Hi, guys, this is my first macbook repair, honestly dont thing i would have made it this
far without watching a bunch of louis rossman videos and pouring thru alot of threads.
Ok, so this board was water damaged and had no power when I got it.
after replacing u5110 I got green light
had short on pp5v_s4..which led me to a short on u6410.
after i replaced that i got the fan to spin...then it died again..no green light
after some searching i found smc_bc_acok was missing...replaced U7100..
Now i have a green light that switches from orange to green and just back and forth..
im missing pp5v_s4 and pp5v_s0 is .024v
I was wondering what creates the pp5v_s4 line? is it u8080
thanks
