[SOLVED]820-2879 with battery doesnot work

[dukefawks]

SMC_ADAPTER_EN - 0.47V is not right, I guess fucked SMC or bad soldering.

After reflow I lost magsafe
After reball I have magsafe but SMC_ADAPTER_EN at 0V
Do you know of which signals SMC_ADAPTER_EN depend? Only 3.42V is required? This way I can check those signals before replace smc or put old one.

SMC is probably dead.

All macbook pro and air boards PPBUS goes 0.3V less when there is problems with SMBUS?
Ok, tomorrow will replace SMC

I replaced smc and now works. Thanks for help.
Can you affirm if all macbook pro and air boards PPBUS goes 0.3V less when there is problems with SMBUS?

Yes, 0.3V less when SMC is not running or battery data bus is fucked.
