MacBook A1706 820-00239-A

[ipetro]

Hello. We are repairing a MacBook that has stopped turning on, with the J4900 connector (power button) flooded (oxidized). consumption 20V/0.650A. There is no image on the external or internal monitor. Caps lock does not turn on in green, there is no startup sound. the coolers do not rotate. The board itself has no noticeable signs of flooding!

Did you test the board alone on the desk?
What voltages did you check?

probably dead CPU ?
I have EDP_INT_AUX_N in short circuit

 

[2informaticos]

If J8500 is disconnected and has no short between pins, then yes, bad CPU.

Is the fingerprint on this model linked to T1?

Yes, come paired from the factory.

Google also helps sometime, or not?
