Hello!, have 820-4924A that is missing PP5VS3, mac turns on in SMC Bypass Mode, boots till half and witches off.

PP5VS3_EN 0V
SMC_ADAPTER_EN 3.45v
3V3_S5 3.3V
3V3_SUS 3.3V
S5_PWRGD from 5V GOES TO 3.3v
PM_DSW_PWRGD 3.4V
PM_BATLOW_L 0V Looks like i am using 85W magsafe 2 fake charger (have only this one ATM), if i remember correctly this board was turning on on genuine charger, but was turning off every few minutes.

Think genuine charger can solve issue? as this charger that i have works with same model board.

Did you turn it on with both charger and battery connected?
Some people reported power issues on this board without battery; didn't face with such problem myself.

So check with original Magsafe 2 charger and good battery, then report back.
