Macbook A1398 Will Run on a PSU but on a Charger/Battery

[Instafixx]

Hello,
Macbook A1398 820-3323/ This device came without the ssd . No Response when put on charger or off battery. Magsafe light is there.
When connected to a PSU to check current draw the machine boots and gives the question mark sign.

No Corrosion on the board

PPBUS and PP3V42 all ok

I suppose the board is 820-3332.

The mentioned symptom looks like input lekage problem.
But in such case, original charger shouldn't get light.

What is exact PPBUS_G3H voltage?
Do you get 3V3_S5?

 

[Instafixx]

Original gets light. Knock off doesnt.
PPBUS is 12.56V
PP3v3_S5 is 3.3V checked a C7292/93

Then the problem is not leakage related.

Be aware, this machine requires 85W charger, if battery doesn't hold any charge; or is not properly recognized.
Turns on in SMC bypass mode?

I was using a 60W adapter. Let me ask the customer for a 65W adapter.

85W!

It should turn on in SMC bypass even with 45/60W; tried that?
