Hello I have a 820-2915-A this macbook charges the battery goes green to orange doesnt power on from the power button or the power pads on the board I try new keyboard still the same. I tested this PP3v42_G3H: 3.48v PPBus_G3H: 12.58V pp18v5_dcin_fuse :17.32V pp5v_S5 3.3V pp3v3_S5 3.3V pp3v3_s4 3.3V I dont see any water damage the customer said it just wont power on . Is there anything else I need to test or any idea whats the culprit?
If you have just 3.3v on pp5v_S5 I’d start from that. All the rest seems in order.
Unplug the battery and mag-safe, Press and hold the power button for 10 seconds, Plug the battery and mag-safe back in and see if you get a spontaneous reboot.
