Good afternoon, this Mac came in for repair of the headset not working on one side, I fixed it by changing the U6201. In the final tests the mac stopped turning on, I checked that there was oxidation in the Q7630, I replaced it but with no result.
Sometimes it wouldn't give led in the MagSafe.
I removed the u6201 to eliminate the possibility of it being defective.
Voltage:
PPbus: It oscillates between 12,45V, 12,61 and 12,71V;
pp3v42 3,42V; PP3v3_Sus 0,8V oscillates; PCH_BatLow 3,34V; PLT_RESET_L 30mV;
