the board had prior repair attempted. the board was liquid damaged and was missing an SMC.
if I use charger only, the board always turn on fine.
if I put a charged battery. turn it on, fan spins, use it as normal, it can charge the battery, passed ASD EFI and ASD OSX.
then a couple of hours later the board doesn't turn on. no fan spin. plug MagSafe 2 and it still doesn't turn on.
I'll have to unplug the battery and replugging the battery then the board can turn on.
the keyboard is good, the trackpad is good, MagSafe IO board and flex are good.
same thing without inside the housing.
original MagSafe 2.
I've tried another known working battery.
I've replaced SMC, U7090, D7005. ISL6259 and U7090 so far.
17/18 = 2.7ohms, 27/28 = 20.6ohms on ISL6259.
